A collection of rate limiting implementations in Go, demonstrating different approaches to throttling HTTP requests.

This repository showcases three different rate limiting strategies for HTTP APIs:

1. tollbooth - Third-party library implementation using didip/tollbooth
2. tokenbucket - Custom fixed-window rate limiter implementation
3. clientlim - Per-client IP-based rate limiter with automatic cleanup

• Simple HTTP server examples with /ping endpoint
• JSON response formatting
• Configurable rate limits and time windows
• HTTP 429 (Too Many Requests) responses when limits exceeded

• Go 1.24.4 or later

git clone https://github.com/senutpal/snailtrail.git
cd snailtrail
go mod download

cd tollbooth
go run .

cd tokenbucket
go run .

cd clientlim
go run .

Each server runs on http://localhost:8080. Test the /ping endpoint:

curl http://localhost:8080/ping

• tokenbucket: 2 requests per second
• clientlim: 2 requests per second per IP address
• tollbooth: 1 request per second
