Tollbooth
A Go middleware for rate-limiting HTTP requests using token bucket algorithm with flexible key selection.
What is Tollbooth?
Tollbooth is a generic HTTP rate-limiting middleware for Go applications. It helps protect web services from excessive traffic by enforcing request limits based on various criteria like IP address, headers, HTTP methods, and basic auth usernames. It uses Go's embedded `time/rate` library with a token bucket algorithm for efficient, storage-free rate limiting.
Go developers building HTTP servers or web services that need to protect against traffic spikes, abuse, or ensure fair usage, particularly those using standard Go HTTP or frameworks like Gin, Chi, and Echo.
Developers choose Tollbooth for its simplicity, thread safety, and explicit configuration without external storage dependencies. Its unique selling point is flexible rate limiting by multiple request attributes (IP, headers, methods, basic auth) with customizable rejection handling and standard compliance headers.
