devproxy

Local HTTPS dev subdomains for Docker Compose projects. One label, one command, real TLS.

# docker-compose.yml
services:
  web:
    build: .
    labels:
      - devproxy.port=3000

devproxy up
# → https://swift-penguin-myapp.mysite.dev

devproxy up --slug my-app
# → https://my-app-myapp.mysite.dev

Features

• Zero config — one Docker label is all you need
• Real HTTPS — auto-generated CA + wildcard cert via rcgen (no mkcert)
• Self-healing — watches Docker events, no manual cleanup
• No external proxy — single Rust binary, no Caddy/Traefik/nginx
• Human-readable slugs — random adjective-animal subdomains
