It offers three implementations: a basic Limiter that accounts for CPU delays, a LeakyBucketLimiter following the leaky bucket algorithm with burst capacity, and a StrictLimiter that enforces a hard rate floor without bursts. The package has no external runtime dependencies and supports Python 3.9 and later.\n\nYou use it by instantiating a limiter with a rate (requests per second), then calling `await limiter.wait()` before executing rate-limited work. It integrates directly into async functions and plays well with `asyncio.gather()` and other concurrency patterns. The library is stable and typed, making it suitable for production async applications that need to throttle API calls, database queries, or other I/O-bound operations.","worth_installing":"Yes, with a note on maintenance. The package is stable, has no dependencies, and solves a common async concurrency problem cleanly. However, it has not been released in over five months despite an active repository, so check whether your use case aligns with the three limiter flavors offered before committing to it.
