Awesome Go

Awesome

A curated list of awesome libraries, tools, and resources for the Go programming language.

Contents

Web Frameworks

  • Gin - Arguably the most popular and widely used Go web framework. Although it has a Martini-like API, it is extremely fast thanks to its Radix tree-based routing. It has a large community and a rich ecosystem of middleware. It is one of the safest starting points for new projects.
  • Fiber - A framework that is extremely easy and enjoyable to use, strongly inspired by Express.js from the Node.js world. It is built on top of fasthttp instead of Go's standard net/http package, making it one of the fastest web frameworks available. It is very easy to adapt for developers with Express experience.
  • Echo - Another popular high-performance, minimalist, and extensible framework. It features a powerful router, a rich set of middleware, and built-in support for template rendering. It is often mentioned alongside Gin and Fiber as one of the best minimalist frameworks.
  • Chi - Stands out for being lightweight, idiomatic, and composable. The biggest advantage of chi is its full compatibility with Go's standard net/http package. This means you can use existing net/http-compatible middleware without any changes. It is one of the frameworks most faithful to Go's philosophy.
  • Gorilla/Mux - One of the oldest and most established routers in Go. It is more of a powerful router and dispatcher than a full-fledged framework. It forms the basis of many large and legacy projects. It is known for its flexible routing rules and robustness. Although it is now community-managed, it is still very common.
