An Elixir OTP GenServer that implements a token bucket algorithm for rate limiting calls to external APIs or services.
What is ex_rated?
ExRated is an Elixir library that provides fast, efficient rate limiting for services and API calls. It implements a token bucket algorithm as an OTP GenServer, allowing developers to prevent excessive requests and manage resource usage. The library supports multiple named buckets, high-performance operations, and optional persistence to disk.
Elixir developers building applications that need to enforce rate limits on external API calls or internal services, particularly those using the Phoenix framework who require a plug for API rate limiting.
Developers choose ExRated for its high performance (benchmarked under 1 microsecond per operation), simplicity, and adherence to Elixir/OTP conventions for reliability in concurrent environments. It offers a minimal yet powerful interface without unnecessary complexity.
Overview
ExRated, the Elixir OTP GenServer with the naughty name that allows you to rate-limit calls to any service that requires it.
