Inngest Rate Limits

Rate limit definitions for the Inngest API surface. Inngest's primary consumer-facing limits are execution volume and concurrent steps per plan tier, plus a 512 KB event ingestion payload ceiling and platform-level fair-share scheduling. Function-level concurrency, throttling, batching, debounce, and rate limiting are configured per function via the SDK.

Inngest Rate Limits is the machine-readable rate-limit profile for Inngest on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 8 rate-limit definitions, across the platform, hobby, pro, and enterprise tiers, measuring payload_bytes, executions_per_second, executions_per_month, and concurrent_steps.

The profile also includes 4 backoff/retry policies defined and response codes documented for payloadTooLarge, throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include AI Agents, Background Jobs, Cron Jobs, Durable Execution, and Event-Driven.

Policies

Multitenant Fair Queue
The Inngest runner uses a multitenant-aware, multitier queue designed for fairness so noisy neighbors cannot starve other tenants.
Backoff Strategy
Clients should implement exponential backoff with jitter, honoring the Retry-After header when present.
Quota Reset
Monthly execution quotas reset at the start of each calendar month in UTC.
Fair Use
Even on uncapped Enterprise contracts, sustained usage that materially impacts shared infrastructure may be subject to fair-use throttling.
