Acknowledgments
PatchPanel is built on top of HAProxy plus a long list of excellent open-source projects. We are grateful to the developers and communities behind them.
The thing PatchPanel manages
HAProxy - High-performance TCP/HTTP load balancer and reverse proxy
- Website: haproxy.org
- License: GPL-2.0
- Usage: The reverse proxy PatchPanel renders configuration for, validates, and reloads via the master CLI socket. PatchPanel is, fundamentally, a state-driven UI on top of HAProxy.
certbot - ACME client for Let’s Encrypt and other certificate authorities
- Website: certbot.eff.org
- License: Apache 2.0
- Usage: Issues and renews TLS certificates via DNS-01 / HTTP-01 challenges. PatchPanel wraps it with a state-driven configuration and renewal scheduler.
Backend dependencies
Express.js - Fast, unopinionated, minimalist web framework for Node.js
- Website: expressjs.com
- License: MIT
- Usage: Serves the management API and the SPA shell.
zod - TypeScript-first schema validation with static type inference
- Repository: github.com/colinhacks/zod
- License: MIT
- Usage: Validates every state document on save and surfaces precise field-level errors back to the UI.
better-sqlite3 - Fast, simple, synchronous SQLite3 bindings for Node.js
- Repository: github.com/WiseLibs/better-sqlite3
- License: MIT
- Usage: Audit log storage.
croner - Cron job scheduler for Node.js
- Repository: github.com/Hexagon/croner
- License: MIT

@maxmind/geoip2-node - MaxMind GeoIP2 database reader
- Repository: github.com/maxmind/GeoIP2-node
- License: Apache 2.0
- Usage: Resolves client IPs to country/city/ASN for the dashboard origin panels. Optional — PatchPanel runs without it.
ws - Simple to use WebSocket client and server library
- Repository: github.com/websockets/ws
- License: MIT
- Usage: Real-time log streaming and stats push.
multer - Node.js middleware for handling multipart/form-data
- Repository: github.com/expressjs/multer
