Gin

A high-performance HTTP web framework for Go featuring a Martini-like API with speeds up to 40 times faster.

Gin utilizes a custom version of HttpRouter to manage routing with a zero-allocation strategy, making it one of the fastest frameworks in the Go ecosystem. It provides essential middleware support, crash recovery, and JSON validation out of the box. Developers use its grouped routing and recovery features to build scalable microservices that handle massive traffic loads without the overhead of bulkier frameworks.
