Fiber

Fiber is an Express.js inspired framework for Go, running on fasthttp (the fastest HTTP engine for Go). v3 brings generic support and better middleware.

When to Use

• Extreme-Performance Go Web Services: Developing HTTP APIs on top of fasthttp with zero memory allocation goals.
• Express-like Ergonomics in Go: Writing web handlers with an intuitive, familiar API similar to Express.js.
• High-Concurrency Low-Latency Microservices: Handling tens of thousands of concurrent connections with minimal CPU overhead.
• Real-Time WebSockets & Streaming: Building low-latency chat, game servers, and IoT ingestion gateways.
