## What it is
Armor is a modern HTTP server and reverse proxy written in Go, supporting HTTP/2, automatic Let's Encrypt TLS certificates, WebSocket proxying, and virtual hosts with path-level routing. Its functionality is built on a plugin interface, making custom extensions straightforward.

## Use cases
- serve a website with automatic https certificates
- reverse proxy http and websocket requests
- host multiple sites on one server with virtual hosts
- redirect http to https and handle www redirects
- serve static files with gzip compression
- add security headers like hsts and csp to responses

## When to choose
- you want a simple Go-based web server with automatic Let's Encrypt TLS
- you need lightweight reverse proxying with virtual host routing
- you want an extensible plugin-based HTTP server

## When to avoid
- you need an actively maintained project - the last release was in 2020
- you need battle-tested production proxying - Caddy or nginx are safer choices
- you need advanced load balancing or service mesh features

## Facets
- artifact type: service
- maturity: abandoned
- function: http-server, proxy, routing, middleware
- domain: web-development, backend, networking, self-hosted
- platform: windows, go, cross-platform
- tags: http2, letsencrypt, reverse-proxy, tls, websocket, gzip, cors, virtual-hosts, load-balancing, linux, macos
