Fiber is a web framework for Go that brings Express-inspired patterns to the language while prioritizing performance.
Fiber addresses the need for rapid web development in Go without sacrificing speed or resource efficiency. It builds on Fasthttp, Go's fastest HTTP engine, and emphasizes zero memory allocation to minimize garbage collection overhead. The framework adopts Express conventions and syntax patterns that Node.js developers find familiar, lowering the learning curve for teams transitioning to Go or working across both ecosystems. This approach lets developers write idiomatic Go code using a mental model they may already know.
Teams should choose Fiber when they need a performant REST API or web service in Go and value developer ergonomics alongside runtime efficiency. It suits projects where Express-like routing and middleware patterns feel natural, and where the performance characteristics of Fasthttp matter—whether for high-throughput services or resource-constrained environments. The framework is particularly relevant for teams with Node.js experience looking to leverage Go's concurrency and compilation benefits without relearning web framework conventions from scratch.
The project maintains active test coverage and passes its test suite consistently. Benchmarking data is tracked and published to document performance characteristics. Documentation is comprehensive and actively maintained. The codebase receives regular updates and refinements across its core functionality.
