Apple Safari Rate Limits

Published throttling and flow-control limits for the Safari developer surface. This file replaces a 2026-05-04 bulk-sweep scaffold that asserted free/professional/ enterprise tiers with 10/100/1000 requests-per-minute quotas — Apple publishes no such tiers and never did. What Apple actually publishes is protocol-level flow control and an overload status code on the Web Push service; there are no numeric per-key request quotas and no rate-limit response headers anywhere on this surface.

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

It captures 6 rate-limit definitions, measuring unacknowledged_requests, concurrent_streams, consecutive_requests, jwt_refresh, and payload_bytes.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled, throttledReason, payloadTooLarge, serviceUnavailable, and shuttingDown.

Tagged areas include Apple, Browser, Web Push, Rate Limiting, and Throttling.

Policies

Backoff on 429/500/503
HTTP 429 (TooManyRequests), 500 (InternalServerError) and 503 (ServiceUnavailable / Shutdown) are the documented retryable conditions. No Retry-After header is sent, so a client must choose its own backoff.
Persistent connections
"Your service should maintain TLS encrypted connections to APNs." Reconnect churn, not request volume, is the main documented failure mode.
