A Redis module written in Rust that adds a single CL.THROTTLE command implementing the generic cell rate algorithm (GCRA) for distributed rate limiting. It provides a language-agnostic, rolling-window rate limiter that plugs into any Redis deployment without background drip processes.

Use cases

• rate limit API requests per user or IP in Redis
• replace hand-rolled Lua rate limiting scripts
• implement distributed throttling across microservices
• throttle actions globally across an entire system
• add rolling-window rate limiting with a single Redis command

When to choose

• you already run Redis and want a fast, battle-tested rate limiter as a module
• you need GCRA semantics with a rolling window and no background jobs
• you want language-agnostic rate limiting shared across services

When to avoid

• you cannot load custom modules into your Redis instance (e.g. some managed services)
• you need a standalone rate limiter outside Redis
• you need actively developed features - the project is in best-effort maintenance mode
