Instantdb Rate Limits

InstantDB advertises unlimited API requests on every plan, so the primary hard limits are storage-based (1GB Free, 10GB Pro, 250GB Startup) rather than per-minute request quotas. Instant operates platform-level abuse and fair-use protections on the Admin HTTP API and the realtime sync WebSocket; specific numeric throttles are not published. Per-tier and per-endpoint values are not reconciled in this artifact.

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

It captures 5 rate-limit definitions, measuring requests, storage, connections, and seats.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Database, Realtime, Sync, Backend, and Local First.

Ceilings scale with plan storage allotment rather than request-rate quotas.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429.
