## What it is
Fiber is an Express-inspired web framework for Go built on top of Fasthttp, focused on zero memory allocation and high performance. It provides Express-style routing, middleware, JSON APIs, static file serving, and a batteries-included ecosystem of middleware, storage drivers, and template engines.

## Use cases
- build a rest api in go
- create a high-performance http server
- serve json endpoints with routing and middleware
- migrate from express to go
- build a web application with templates and static files
- add rate limiting and logging middleware to a go server

## When to choose
- you want an Express-like developer experience in Go
- raw HTTP throughput and low memory allocation matter
- you need batteries-included middleware, storage, and template support

## When to avoid
- you need net/http ecosystem compatibility, since Fiber is built on Fasthttp
- you rely on libraries requiring standard http.Handler interfaces
- you need HTTP/2 or HTTP/3 support out of the box

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, http-server, routing, middleware, templating, rate-limiting, websocket
- domain: web-development, backend, apis, developer-tools
