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.
Traffic under control
Per-key and per-IP rate limits enforced transparently.
Fewer round trips
Tag-based cache invalidation reduces upstream load significantly.
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.
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.
Full visibility
Structured trace IDs and latency waterfalls for every request.
Contract-first
Automatic request/response schema validation from your OpenAPI spec.
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.
