PartialWebSocket hibernationA socket stays open while the object sleeps, and a message wakes the object.Orange emulates hibernation, and real hibernation is coming soon. When an object with an open accepted WebSocket is idle, Orange drops the object and its in-memory state and keeps the socket open. The next message builds a new instance of the object. The Rivet actor stays running the whole time, and it sleeps once the last socket closes. A client stays connected, but the actor does not sleep while it does. 16/19 pass

Why

Rivet 3 has paused WebSocket hibernation, so an actor cannot sleep with a socket open. Orange hibernates the object inside the running actor instead.

What to do

Have clients reconnect on any close, and don't depend on one close code. Keep anything that must survive hibernation or a restart in storage. Close sockets you no longer need, so the actor can sleep.

What to plan for

An object with an open socket is always a running actor and does not scale to zero: the actor, its sockets, and their state stay in memory. Before the emulation, an idle awake object cost about 1.1 MB in total, in Orange and the Engine, and each idle socket on one object cost about 0.2 MB. About half of an object's cost stayed after it slept. Measured through orange serve on one machine, with 1,000 idle objects or 1,000 idle sockets on one object, and not measured again with the emulation. It is not a limit.
A deploy closes open sockets. On one cluster, each client reconnected on the first try: 1012 on 4 sockets and 1011 on 1. The object is a new instance, and storage survives. In-memory state and the old sockets do not. Whether the object gets webSocketClose during a rollout is not measured.
Old and new runners overlap for about 100 s during a rollout, and the Engine can place new objects on the old runner then. Those clients get cut off soon after opening.
Under orange dev, a restart closes open sockets with 1012 and a crash with 1006. In both cases a reconnect works and storage survives.
Orange pings every network socket every 30 s, because Cloudflare closes idle sockets on pool URLs at 125 s with 1006. With pings, idle sockets stayed open until a rollout closed them at 695 s. A Worker and its objects never see the pings. wrangler dev kept idle sockets open for 360 s with no pings. Real Cloudflare is not measured: its docs say idle sockets get closed and recommend a heartbeat.
A client whose connection is cut gives the object webSocketClose with 1006 within about 1 s. A client that stays connected but stops answering pings is closed with 1006 at about 90 s. The object sleeps after both.
webSocketClose gets 1001 "gateway disconnected" where a client closed cleanly with 1000. wrangler dev passes the client's code.
The object hibernates, but its actor does not sleep with a socket open. Real projects' steps that wait for every actor to sleep fail with Some actor was still awake. The real-project results show each of those steps again under a sleep check that also accepts the emulation.

SQLite

Durable Object SQL and D1 run on RivetKit's SQLite 3.46. It is a different build from workerd's, so most SQL runs the same and a known set does not. Each row says what to write instead.

Does not workMath functions: cos, sin, sqrt, pow, floor, ceil, and the restAvailable.Fails with no such function: cos, in Durable Object SQL and in D1. 0/5 pass

Why

RivetKit's SQLite is built without the optional math function set.

What to do

Compute in JavaScript after you read the row, or store the computed value in a column. abs() and round() are core SQLite and run.

Results

api-tests--sql-test > main Error: no such function: cos at offset 7: SQLITE_ERROR Fail

Why

RivetKit's SQLite is built without that optional grammar.

What to do

Write DELETE FROM t WHERE rowid IN (SELECT rowid FROM t WHERE ... ORDER BY ... LIMIT n). The same form works for UPDATE, and it runs on Cloudflare too.

Results

synthetic--do-sql-test > deleteWithLimit Error: near "LIMIT": syntax error at offset 19: SQLITE_ERROR Fail

Why

RivetKit returns finished results and has no scan counters. Orange has no per-row billing to match.

What to do

Do not build cost limits or query-plan checks on this number. To check that a query uses an index, run EXPLAIN QUERY PLAN.

Results

Why

It comes from sqlite3_changes(), which does not see those writes.

What to do

Use it to learn how many rows a statement changed. Do not use it as a billing estimate.

Does not workSQL that Cloudflare's authorizer blocksRejects ATTACH, most PRAGMAs, and internal functions, also inside DEFAULT expressions.They run, against the object's own database. Orange blocks only reserved table names and transaction control. 0/6 pass

Why

RivetKit's SQLite has no authorizer hook. An object's code is trusted app code and each object has its own database, so this does not cross a boundary.

What to do

Code that runs on Cloudflare runs the same here. If you may go back to Cloudflare, keep to its allow-list, because Orange will not stop you.

PartialReserved _cf_ tables, such as _cf_KVReading them fails with access to _cf_KV.key is prohibited.Reading them also fails, with not authorized. 1/3 pass

Why

Orange blocks the names with a text check, not a SQLite authorizer, so the message cannot name the column.

What to do

Treat any error here as a refusal. Do not match on its text.

Results

sqlite-surface: reserved names: reading _cf_KV is rejected Pass workerd pass

WorksRivet's _rivet_ tables in sqlite_masterNo such tables. Code can dump every table it finds, apart from _cf_.Orange leaves RivetKit's _rivet_ tables out of sqlite_master, sqlite_schema, and PRAGMA table_list, so code that walks every table and dumps it works. A query that renames the name and tbl_name columns, or only counts or aggregates rows, still sees them, and reading one fails with not authorized. 2/2 pass

Why

RivetKit keeps its internal tables in the object's own database.

What to do

Do not name your tables _rivet_*. If you count or aggregate over sqlite_master, skip names that start with _rivet_ as well as _cf_.

Results

sqlite-surface: reserved names: sqlite_master lists no _rivet_ table Pass workerd pass
sqlite-surface: dump: every table sqlite_master lists can be read Pass workerd pass

PartialMulti-statement exec()Bindings apply to the last statement. Only its rows return.Unbound scripts run and return the last statement's rows. Bindings on a script throw OpenOrange does not yet support bindings on multi-statement SQL. 1/2 pass

Why

RivetKit's script call takes no bindings.

What to do

Send a bound statement on its own. For several together, wrap them in ctx.storage.transactionSync().

Not proven on a cluster: one cluster outage had matching symptoms. 1/2 pass

Why

A RivetKit bug: the envoy client's read loop has no deadline, so nothing notices silence while connected.

What to do

Until the fix ships, watch the node count in /pools/{pool}/nodes and restart a runner that has no node.

Both an EmailMessage and the message object work, with Cc, Bcc, and attachments. A recipient outside the address limits is refused before anything is sent. Without the variable, send() throws an error that names it. 4/4 pass

What to do

Set ORANGE_EMAIL_SMTP_URL to your mail provider's SMTP endpoint.

What to plan for

You bring the SMTP provider. Orange does not check sender domains or verified destinations. Your provider does its own checks.

WorksInbound email: email(), forward(), and reply()Email Routing delivers mail to the email() handler, and message.forward() and message.reply() send it on.A message POSTed to /cdn-cgi/handler/email runs email(): raw MIME, or a SendGrid or Mailgun inbound webhook. forward() and reply() send through ORANGE_EMAIL_SMTP_URL, and setReject() answers 400. With ORANGE_EMAIL_INBOUND_SECRET set, a wrong secret gets 401 and email() does not run. orange serve serves the route only when the secret is set. The evidence here runs on orange dev. 7/7 pass

Why

Email Routing itself, Cloudflare's MX and routing rules, is Cloudflare-only. Orange has no mail server, so something else must receive the mail and POST it.

What to do

Point your mail provider's inbound webhook at /cdn-cgi/handler/email, with the secret.

What to plan for

Email Routing is Cloudflare-only. A provider such as SendGrid or Mailgun must receive the mail.

What to do

Run a headless Chrome that the runner can reach, and set ORANGE_BROWSER_CDP_URL to it.

What to plan for

You run the browser. All sessions share it, so they share cookies and storage.

Changes

Sets POLICY_AUD and TEAM_DOMAIN in wrangler.jsonc vars, with TEAM_DOMAIN pointing at a local JWKS server that the scenario runs The production build refuses every request without Cloudflare Access settings. The scenario signs real Access JWTs, and the Worker verifies them through its own jose code. The Vite build writes build/server/wrangler.json, so .dev.vars written after the build cannot reach it.
A build step removes "legacy_env":true from the generated build/server/wrangler.json Orange's wrangler 4.129.0 refuses the field that the project's Vite plugin 1.29.0 writes, and orange dev exits at boot. Removing it shows what lies behind that error. Repro: repros/generated-legacy-env.

With emulated hibernation, 25 of the 26 steps that fail for lack of hibernation pass, in 23 projects

Orange emulates hibernation. When an object with open accepted WebSockets is idle, Orange drops the object and keeps its sockets open, and the next message or alarm builds the object again. The Rivet actor stays running the whole time, so the memory and the cost of each connected object remain. This is not Cloudflare's hibernation, where a hibernated object uses no memory and is not billed for duration. An emulated result shows what a step does when the sleep check also accepts this state as asleep. It never changes the status of a step or a claim. A project that fails only hibernation steps, and passes them all this way, shows as works, with emulated hibernation, and is counted apart from the projects that work.

26 of 26 steps reran this way, at OpenOrange ee0b731, 2026-11-10.

Worksstarbasedbouterbase/starbasedborange deploy · Free cluster · 2026-11-05A SQL database over HTTP and WebSocket, built on a Durable Object's SQLite. 7/7 pass 1 not applicable

What ran

The API refused a request with no token. A client created a table, inserted rows, ran a transaction, used the REST API and JSON export, and queried over a WebSocket. The table survived an idle wait and a real rollout.

Where it falls short

The cron callback step did not apply: it calls a local server, which a pool can't reach.
The recorded run is the third attempt. The first was stopped because the old build might still have been serving. The second failed on rows the first had left and on a wrong sleep check in the test runner.
The API needs a token, and there is no page to open in a browser.

Steps

a request without a token gets 401 Pass
a client creates a table, inserts rows, and reads them back Pass
the README's $1 query and transaction return their rows Pass
the REST API writes a row, and the JSON export sees it Pass
a WebSocket client queries the same database Pass
a cron task's alarm calls the task's callback host The callback host is a local HTTP server, which a pool cannot reach Not applicable
the table survives the object's sleep Waited 30 s idle with no socket open. Sleep itself is not proven on a pool. Pass
the table survives an orange dev and engine restart Pass

Workstldrawtldraw/tldrawrivet deploy · Free cluster · 2026-11-05The sync backend of tldraw's multiplayer whiteboard, with one Durable Object per room and assets in R2. 6/6 pass

What ran

Assets uploaded to and read from R2 on a Google Cloud Storage bucket, through Orange's S3 settings. Two clients synced pages over WebSockets, a late joiner got them, and a page survived the room emptying and a real rollout.

Where it falls short

This is the backend only, with no editor to open.
The image needed the Worker bundled by hand first, because the Orange it ran on could not install workspace: packages inside the image.
Only the object reads and writes the project uses ran against Cloud Storage.

Steps

an uploaded asset is stored once in R2 and comes back Pass
a page pushed by one client reaches the other client in the room Pass
a client that joins while the room is live gets the page in its hydration Pass
a connected client keeps the room alive through an idle period, and its next push commits Pass
when everyone leaves the room saves to R2 and sleeps, and the page comes back from R2 Waited about 16 s after the sockets closed, past the 10 s sleep timeout. Sleep itself is not proven on a pool. Pass
a page pushed before an orange dev and engine restart is there after it Pass

Workscomputercloudflare/computerrivet deploy · Free cluster · 2026-11-05A workspace in a Durable Object, with a filesystem and a shell that runs in a Dynamic Worker. This was the first Dynamic Worker on a cluster. 6/6 pass

What ran

Files written through the object read back, each workspace stayed separate, and a shell in a Dynamic Worker read and wrote the same files. A bundled skill mounted read-only. Files survived an idle wait and a real rollout.

Where it falls short

The image needed the Worker bundled by hand first, because the project's package comes from its monorepo.
The scenario does not touch the R2 mount. A separate check read and listed a Cloud Storage object through it. The project's mount is read-only.

Steps

the Worker lists its routes, and refuses paths outside the workspace Pass
a file written through the Durable Object reads back, and each workspace is separate Pass
a shell in a Dynamic Worker reads and writes the Durable Object's filesystem Pass
the skill bundled with the Worker is mounted read-only Pass
files survive the Durable Object's sleep, and the shell still runs Waited 30 s idle with no socket open. Sleep itself is not proven on a pool. Pass
files survive a restart, and the shell still runs Pass

What ran

The page and its JSON read from the store. The real cron fired on the pool, and three failing passes opened an incident, which survived an idle wait and a real rollout.

Where it falls short

Its origin points at a host that never answers, so the pool doesn't probe the project's real site. So every component reads down, and that outage comes from this setup.
Two steps did not apply, because they need an origin that answers or recovers.
Operator alert email needs a real credential.
A binding to the project's jobs Worker points at a Worker that isn't deployed. No step called it.

Steps

the status page and its JSON read from the store Pass
the one-minute cron runs a probe pass into the object It asserts a healthy origin. The local scenario serves one on 127.0.0.1, which a pool can't reach, so the origin here is a host that never answers Not applicable
three failing passes open an incident, and the page shows it Pass
the open incident survives the object's sleep Waited 30 s idle with no socket open, and the cron wakes this object each minute. Sleep itself is not proven on a pool. Pass
the open incident survives a restart Pass
after the restart, the cron runs again, and two good passes resolve the incident It needs an origin that recovers, which a pool can't reach Not applicable

Partialpartykitcloudflare/partykitrivet deploy · Free cluster · 2026-11-05A collaborative text editor fixture on PartyServer, with Yjs documents in Durable Objects. 5/6 pass

What ran

Two editors synced edits both ways over WebSockets, and a custom message reached the others. A document was saved when its room emptied, came back after an idle wait, stayed separate from another room's, and survived a real rollout.

Where it falls short

Editors staying connected across a room's hibernation failed, as expected: WebSocket hibernation is not available on Rivet 3, so open sockets keep the object awake.
The editor client isn't in the deployed assets, so there is nothing to open in a browser.

Steps

editors stay connected across the room's hibernation, and an edit wakes it A client socket stayed open or a request ran within the idle window for 90000ms, so the object could not sleep Fail
two editors sync edits in both directions Waited 30 s idle with no socket open. Sleep itself is not proven on a pool. Pass

Workssupermemorysupermemoryai/supermemoryrivet deploy · Free cluster · 2026-11-05Supermemory's MCP server, which gives AI clients a memory, with a Durable Object for each user's active space and for upload sessions. 4/4 pass

What ran

The server described itself and its OAuth metadata, refused a client with no token, and refused an unknown upload token. With a real Supermemory sign-in, a token was accepted on the pool, an upload session worked once and refused a second use, and the active space carried across connections.

Where it falls short

Uploads don't work for a real client on a pool URL. The Worker builds its upload URL from MCP_RESOURCE, which stays on Supermemory's production host so that tokens match, so a client following it gets a 401 from production. The passing step posted the same path to the pool by hand.
The image needed build.command removed after running it by hand, because the Orange it ran on refused a custom build.
The sign-in step ran by a separate script, after two attempts stopped on that script's own checks.

Steps

serves the server description and the OAuth resource metadata Pass
an MCP client without a token gets 401 with the resource metadata Pass
SpaceState refuses an upload token with no session Pass
the active space is stored in SpaceState and an upload session is consumed once Ran once with a real Supermemory sign-in, by a separate script through the project's public MCP API. The upload went to the pool by hand, because the Worker advertises Supermemory's production host for uploads. Pass

How these runs were set up

Each scenario ran on one shared Free cluster, recorded as Engine 3.0.0 when it was created, the day before these runs. That version comes from the creation record, and was not read during the runs. Each project then got its own Free cluster, where one real request proved it. Those clusters report Engine 3.0.0.
Only starbasedb used orange deploy's upload and rollout. The others used the image orange deploy --dry-run writes, uploaded and rolled out with the Rivet CLI.
Sleep isn't proven on a pool. The Engine API's actor timestamps are null, and these images log no lifecycle lines, so sleep steps wait past the idle window and read state afterward. A restart step is a real rollout to a newly built image.
A deploy reports done before the new build serves, so each scenario waited for the old node to leave and a project-specific request to succeed.
The Orange under test was a local merge of the CLI and Durable Object branches, before they landed.

Feature matrix

624 items: every binding, handler, API, module, flag, config key and limit. A red dot is a cited test that fails in the latest run.

Supported.: OpenOrange implements the Cloudflare API.
Alternative.: The same API, on an OpenOrange backend such as Rivet Actors.
Partial.: Works with a known difference. The row says which.
Stub.: The binding loads; every call throws an error that names it.
Rejected.: Fails at config load or Worker load with a clear error.
Unsupported.: Missing, ignored, or wrong without a clear error.
N/A.: Deploy-only, workerd-only, or experimental. Not scored.

Bindings

Supportedvars (string values)Each string in vars appears on env as a string.Wrangler converts each string var to a plain_text binding, and Orange puts the string on env. 4 files

Notes: Named environments follow Wrangler's rules, because Orange reads the config with Wrangler's unstable_readConfig.

Supportedvars (JSON values)Each non-string value in vars appears on env as a parsed JSON value.Wrangler converts each non-string var to a json binding, and Orange puts the value on env. 3 files

Notes: A .dev.vars or .env key with the same name replaces the JSON value with a string.

Supported.dev.vars secretswrangler dev loads keys from .dev.vars (or .dev.vars.<env>) into env as secret text.Orange calls Wrangler's unstable_getVarsForDev, so .dev.vars keys reach env as strings, like wrangler dev. 3 files

Notes: A .dev.vars key replaces a var with the same name. It does not replace a binding of another type, such as a Secrets Store secret. When the config has secrets.required, only listed keys and keys that are also vars load, and a missing required key prints a warning.
Source: src/config/load-wrangler.ts:889-919 src/config/load-wrangler.ts:1435-1460 src/runtime/bindings.test.ts:138-148

Supported.env secretsWhen no .dev.vars file exists, wrangler dev loads .env files into env as secret text.Orange gets the same behavior from Wrangler's unstable_getVarsForDev. A .env key reaches env as a string. 2 files

Notes: Orange passes no custom env file list, so Wrangler reads its default .env files. CLOUDFLARE_LOAD_DEV_VARS_FROM_DOT_ENV and CLOUDFLARE_INCLUDE_PROCESS_ENV apply as in Wrangler. Verified by loading a config with a .env file and no .dev.vars.
Not verified by a test: Not covered by a repository test. Verified once by a manual config load on the devbox.
Source: src/config/load-wrangler.ts:893-906 src/config/load-wrangler.ts:1435-1460

Partialsecrets_store_secretsget() returns the secret value from the account Secrets Store.get() reads the value from .dev.vars in the project root, then from the host process.env. 4 files

Notes: Orange does not call the Secrets Store API and does not read .env files for this binding. A missing value rejects with Secrets Store binding "<NAME>" is not configured locally.

Partialversion_metadataenv binding with the Worker version id (a UUID), the version tag, and the version timestamp.id is a SHA-256 hex digest of the bundle and the normalized config. tag is always "dev". timestamp is the build time. 4 files

Notes: The id changes only when code or config changes. Code that parses id as a UUID fails.

Partialunsafe.bindings unsafe_evalThe unsafe_eval binding has eval(), newFunction(), newAsyncFunction(), and newWasmModule().Wrangler emits unsafe_unsafe_eval, and Orange maps it to an UnsafeEval object built on node:vm. 3/4 pass · 3 files

Notes

unsafe-test passes 4 of 5. basics fails because a plain eval('') does not throw in Orange. Workerd forbids code generation outside the binding.

Stubunsafe.bindings of a type other than unsafe_evalPasses a binding of any type through to the Workers runtime without Wrangler validation.Wrangler emits unsafe_<type>. Orange loads it as a stub that throws unsafe_<type> binding "<NAME>" is not supported by OpenOrange. See the OpenOrange bindings documentation for supported bindings. 6 files

Notes: Config load prints a [config-warning] line. Any member read returns a function that throws the message synchronously when called. Code that never calls the binding keeps working. The unsafe key is accepted only when it holds bindings and nothing else.

Alternativekv_namespaces (Workers KV)Binds a Workers KV namespace: a global, eventually consistent key-value store with edge caching.Each namespace id is an Orange-internal SQLite Durable Object on Rivet Actors. Data persists under .open-orange/rivetkit across orange dev restarts. 0/1 pass · 7 files

Notes

Reads see writes at once. Cloudflare can take 60 seconds or more to show a write in other locations. Orange has no edge cache. The local id is preview_id, then id, then the binding name, like wrangler dev. Upstream kv-test fails 0 of 5 because the conformance runner drops workerd kvNamespace bindings, not because of Orange's KV.

Notes

max_concurrency is ignored. After an idle period, the first batch waits the whole max_batch_timeout. A queue is shared by name across the orange dev session, so a consumer in another Worker of the session receives the messages. orange dev fails at startup when two Workers declare a consumer for one queue. queue-metadata-test fails because the conformance runner drops its queue binding.

Notes: Email Routing is Cloudflare-only, so mail reaches the Worker only when your email provider's inbound webhook, or a script, POSTs it to the route. orange serve serves the route only when ORANGE_EMAIL_INBOUND_SECRET is set, and a wrong or missing secret gets 401. orange dev serves it without the secret, and checks the secret when it is set. forward() and reply() throw when ORANGE_EMAIL_SMTP_URL is not set.

PartialWebSocket hibernationAn object with only hibernatable sockets is evicted from memory. Sockets stay open, and the next frame wakes a new instance.Emulated inside a running Rivet Actor. After 10 seconds with no event, Orange drops the object's instance and keeps the actor and its accepted sockets open. The next message, close, or error on a socket builds a new instance, which gets the sockets with their tags, attachments, and auto-response timestamps before its constructor runs. 2/2 pass · 11 files

Notes

Rivet has paused its WebSocket hibernation, so the actor stays awake while an accepted socket is open, and it sleeps only after its last accepted socket closes and 10 more seconds pass with no event. A connected object keeps its actor, sockets, and their state in memory. An auto-response frame is answered without building an instance or restarting the idle timer.

Partialnode:fsA virtual file system. /bundle holds the Worker's modules, /tmp is per request, and /dev has null, zero, full, and random.Stock Node.js node:fs on the host disk.

Outside every event /tmp is one writable directory for the process, and files have no size limit, as in Node.js. 2/3 pass · 5 files

Notes

workerd makes /tmp read-only during module evaluation and stops a file at 128 MiB; Orange follows Node.js for both. The /tmp files are on disk, not in memory.

How this is scored

The suite is workerd's own tests at v1.20260903.1, run on OpenOrange unchanged, plus 77 Durable Object tests OpenOrange adds. A Node.js test counts only when plain Node.js passes it, so 399 tests of workerd-specific behaviour are left out of every score. 19 tests the runner could not host are also left out.

A claim's status is set from its recorded results, never by hand. Probes run the same step on workerd and OpenOrange, so a row can show both. Real projects run at a pinned commit through orange dev, with changes listed on the row.

The matrix is maintained by hand and checked by tests: every source path it cites must exist and every test it cites must be in the latest run. Data and runner: cloudflare-conformance.

What each Cloudflare product runs on, its status and how to configure it: Bindings.

new-module-registry-test Tests the opt-in new_module_registry flag: unbundled modules resolved as URLs at runtime. Orange always bundles the worker.
ts-webfs-writable-test Tests the Web File System API, which workerd only enables with the experimental enable_web_file_system flag. Cloudflare does not deploy experimental flags.
webfs-test Tests the Web File System API, which workerd only enables with the experimental enable_web_file_system flag. Cloudflare does not deploy experimental flags.
webfs-ts-test Tests the Web File System API, which workerd only enables with the experimental enable_web_file_system flag. Cloudflare does not deploy experimental flags.
