We've added bursty concurrency for Pro and above accounts. When steps need more concurrency than your account limit, Inngest raises that limit to 3x for up to 60 minutes a month.

Size

Each burst starts at 3x your account concurrency limit.

Counting

The budget is 60 minutes. Each minute in which steps run above your limit spends one minute, however many steps start.

Refill

The budget resets every month, at a time unique to your account.

Notifications

Admins receive an email at 25%, 50%, 75%, and 100% of the budget.

Billing

Bursts are not charged. Add concurrency on your billing page if you use the full hour.

Function-level concurrency you set overrides a burst, so a function with its own limit does not burst.

Sandboxes are now in public beta for Pro and higher accounts on the TypeScript SDK.

step.sandbox starts an isolated microVM from inside a function, in under a second, and runs commands in it. Create, commands, and destroy are durable steps on the run trace.

Add sandboxMiddleware() from inngest/experimental on a client at inngest 4.21.1 or newer:

const sandbox = await step.sandbox.create("create-sandbox", {
  name: `job-${event.data.jobId}`,
  vcpu: 1,
  memoryMb: 1024,
});
const result = await sandbox.commands.run("run-tests", "npm test");
await sandbox.destroy("destroy-sandbox");

A Sandbox is one of three sizes: 1 vCPU with 1 GB of RAM, 2 with 2 GB, or 4 with 4 GB. CPU is $0.000011 per second and RAM is $0.000003 per GB per second, charged while the Sandbox is running. Each Sandbox has one hour of active runtime, and paused time does not count. Destroy the Sandbox when you are done with it.

MCP, the CLI, and API keys now support read and write permissions.

For Cloud MCP and the CLI, sign in with OAuth and approve the account, environment access, permissions, and session duration. Read permissions allow inspection. Write permissions allow changes. A call must also be allowed by your account role. OAuth sessions cannot read event keys or signing keys. Run

inngest login --force

to sign in again with different permissions.

API keys are for CI and unattended jobs. Organization admins create them in the dashboard with the same permissions, and can limit a key to one environment. INNGEST_API_KEY overrides a stored OAuth login.

A call without the required permission returns

403

or

insufficient_scope

.

#4780 feat(auth): add cli oauth login

Adds cloud login support to the Inngest CLI. OAuth credentials are stored in the operating system’s credential store and refreshed automatically.

log in

inngest login

check the current session

inngest auth status

start a new login and replace the current session

inngest login --force

revoke the session and remove local credentials

inngest logout

#4781 feat(auth): add mcp oauth support

Inngest Cloud MCP clients can now authenticate via OAuth. Users can now select the account, permissions, environment access, etc. in the Inngest Dashboard.

#4788 fix(debounce): handle removed config during execution

Prevent debounce timeout execution from crashing after debounce configuration is removed from a function.

#4789 fix(api): serialize sandbox bytes written as a number

Sandbox file upload responses now serialize bytesWritten as a number instead of a string.

#4813 fix(api): normalize unknown REST v2 body field errors

REST v2 now returns a clear invalid_request error when a JSON request body contains a field unsupported by the server.

#4816 feat(api): reject unmapped v2 request fields via grpc-gateway fork

API V2 now rejects unknown query parameters and request bodies on endpoints that do not define a body.

#4818 fix(semaphores): improve semaphore iteration, breaking early, etc

improves speed of queue when workers are at their concurrency cap

#4832 fix(cel): Improve certain classes of cel filter errors

CEL run searches now return an explicit error for unsupported fields or operators instead of silently ignoring the filter and returning unfiltered runs.

Blank lines in CEL expressions are now safely ignored.

#4849 fix(queue): close migration requeue routing window

Fixed a queue migration race that could lose a requeue schedule update.

#4855 fix(api): return error when event run status lookup fails

REST API event run lookups now return HTTP 500 when querying run status fails instead of HTTP 200 with an empty response.

#4857 fix(api): REST v1 GET requests should keep their error codes

REST v1 endpoints now preserve non-200 HTTP statuses through the response cache, and only successful HTTP 200 responses are cached.

#4858 feat(api): support CEL queries in REST run lists

REST v2 run-list endpoints now support CEL filtering through the optional query parameter and return additional run metadata.

#4863 fix(debounce): finish source cleanup before execution

Fixed duplicate debounce execution after a crash during queue-shard migration.

#4870 feat(api): define sandbox lifecycle contract

Adds REST V2 API contract definitions for pausing and resuming sandboxes and managing sandbox snapshots.

runs API can optionally return the deferring parent function slug and name

Migration Notes

#4816 feat(api): reject unmapped v2 request fields via grpc-gateway fork

Clients using API V2 must remove unsupported query parameters and must not send request bodies to endpoints without body mappings. Such requests now return HTTP 400 instead of silently ignoring the unsupported input.

Original source

We've added AI Overview, a dashboard that turns the OpenTelemetry-derived gen_ai.* metadata Inngest already captures from your AI calls into a live view of usage, cost, and performance across your environment.

Filter by time range or function to see:

• Usage — AI runs and token counts over time, plus your top functions and models by usage.
• Cost — Estimated cost over time, cost per run, and cost broken down by model and function, alongside your most expensive runs, steps, and sessions. Every cost chart explains that estimates are based on uncached token usage.
• Performance — Call latency by function and model, and your slowest runs, viewable as charts or sortable tables.

Every chart and table links back to the runs, functions, and sessions behind it, so you can go from a spike in cost or latency straight to the run that caused it.

AI Overview is available now and appears under the new AI section in the dashboard sidebar. It reads the same gen_ai.* metadata used elsewhere in the product, so make sure OpenTelemetry is set up to capture AI calls made with the OpenAI, Anthropic, Google Generative AI, or Vercel AI SDKs.

Read the AI Overview docs for the full breakdown of what each section shows.

#4688 fix(queue): isolate unavailable shards

Queue operations spanning multiple shards now tolerate unavailable shards and continue returning results from healthy shards. Shard-group workers also continue trying healthy lease candidates when another shard is unavailable.

None

Validation

#4665 refactor(queue): add scanner runtime

Out-of-tree queue scanner implementations must update Run(ctx, dispatch) to Run(ctx, runtime), use runtime.Dispatch to submit leased work, and may inspect runtime.WorkerSemaphore before scanning. Implementations that call DispatchFunc must handle the returned DispatchedItem; callers may ignore it, or wait on Done() with context cancellation or a timeout.

Callers of LeaseItem must stop passing queue partitions and instead provide item metadata on LeaseItemRequest. Callers of ProcessItem must handle the new (ProcessItemResult, error) return shape.
