## What it is
Bandit is a pure Elixir HTTP server for Plug and WebSock applications, supporting HTTP/1.x, HTTP/2, and WebSockets over HTTP and HTTPS. It is the default HTTP server for Phoenix since 1.7.11 and emphasizes correctness, clarity, and performance.

## Use cases
- serve a Phoenix or Plug web application in Elixir
- replace Cowboy with a faster HTTP server for Elixir apps
- serve WebSocket connections from an Elixir backend
- host an HTTP/2-compliant API server
- run an HTTPS server with strong RFC conformance
- build a lightweight Elixir web server without Erlang Cowboy

## When to choose
- you are building a Plug or Phoenix application in Elixir
- you need HTTP/1.x, HTTP/2, and WebSocket support with high conformance
- you want better HTTP performance than Cowboy in benchmarks
- you value an approachable, well-tested codebase

## When to avoid
- you need a general-purpose HTTP server outside the Plug/WebSock ecosystem
- your stack is not Elixir/Erlang
- you require extensive HTTP-level configuration or proxy features

## Facets
- artifact type: library
- maturity: stable
- function: http-server, websocket, routing
- domain: web-development, backend, apis
- platform: elixir
- tags: plug, phoenix, http2, http1, cowboy-alternative, thousand-island, web-server
