Fauna Rate Limits

Fauna announced End-of-Service in March 2025 and fully shut down its hosted service on May 30, 2025. Historically Fauna throttled by Transactional Operations (TROs / TWOs / TCOs) on a per-database basis with per-plan ceilings, and exposed standard 429 responses. The service is no longer accepting traffic; this artifact preserves the historical rate-limiting shape for archival purposes.

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

It captures 4 rate-limit definitions, measuring operations and GB.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, serverError, and serviceUnavailable.

Tagged areas include Database, Document Database, Serverless, Rate Limiting, and End of Service.

Policies

End of Service
Fauna service was decommissioned on 2025-05-30. New signups closed in March 2025; existing tenants were given a migration window. This rate-limit artifact is archival.
Historical retry pattern
When operational, Fauna returned 429 with Retry-After on quota exhaustion; clients should have used exponential backoff with jitter.
Historical idempotency
Fauna FQL transactions were ACID and idempotent within a single transaction; retries of the same FQL were safe.
