Relay Features

Automatic rate limiting

Per-key, per-IP, and per-endpoint rate limits configured in one line. Relay enforces them transparently — your upstream services never see a flood.

Per-key and per-IP rate limits enforced transparently.

Response caching

Intelligent cache with TTL and tag-based invalidation. Serve identical responses from cache and reduce upstream load by up to 90% on read-heavy routes.

Tag-based cache invalidation reduces upstream load significantly.

Request tracing

Every request through Relay gets a trace ID and a structured log entry. View latency waterfalls, identify slow upstreams, and export traces to your observability stack.

Structured trace IDs and latency waterfalls for every request.

OpenAPI integration

Point Relay at your OpenAPI spec and it automatically validates request/response schemas, generates mock endpoints for dev, and surfaces contract violations in CI.
