Fiber Overview

Fiber is a high-performance Go framework built on fasthttp and inspired by Express. It provides a minimal API and excellent throughput to help developers quickly build low-latency backend services.

Core features and highlights

• Simple and flexible routing with route groups
• Extensive middleware support (logging, CORS, JWT, etc.)
• Static file serving, template engine integration, and error-handling middleware
• Native support for WebSocket, file uploads, and streaming responses

Use cases and target users

Suitable for building high-performance APIs, microservices, real-time applications, and low-latency backends; target users are backend engineers familiar with Go, teams focused on performance and development efficiency, or developers looking to transfer their Express experience to Go.

Key advantages

• Blazing performance: Built on fasthttp for lower latency and higher throughput
• Easy to pick up: Intuitive API design with a gentle learning curve
• Highly extensible: Rich middleware ecosystem and solid plugin architecture
• Active documentation and community: Facilitates rapid development and long-term maintenance

Overall, Fiber is a good fit for developers and teams wanting to build high-performance, maintainable backends in the Go ecosystem with minimal overhead.
