Limiter.io is the high-performance distributed rate limiting layer for APIs. Sub-millisecond latency. Global token buckets. Full operational control.

Rate limiting built for
brutal throughput
Limiter.io sits at your API edge and decides — atomically — whether each request passes. Rules are evaluated inside Redis via Lua scripts, so there are no race conditions and no round-trips. Five algorithms: token bucket, fixed & sliding window, sliding log, and leaky bucket.
Every decision streams to a Kafka pipeline and lands in your live dashboard over WebSockets. Drop in the Go SDK and your Gin server is protected in three lines — and if the gateway ever blinks, the SDK fails open so your traffic never stops.
Choose your throughput tier
Every tier includes the Go SDK, atomic Redis evaluation, real-time analytics, and the full Limiter.io gateway API.
Personal and sandbox use. Rate-limited to 100 req/min.
