Flock is a community alternative to Laravel Herd — a native desktop app that manages local vhosts, SSL certificates, PHP runtimes, database services, and more. Built with Go + Wails + Caddy, it runs on macOS, Linux, and Windows.

Features

• Automatic SSL — Local HTTPS via mkcert, zero configuration
• PHP Management — Multiple PHP versions with per-site FPM pools
• Database Services — MySQL, PostgreSQL, and Redis managed from the GUI
• Node.js Support — Per-site Node version selection
• Plugin Architecture — Extensible to any language stack via a plugin API
• Cross-Platform — Native desktop app for macOS, Linux, and Windows
• System Tray — Runs quietly in the background, always accessible

Core layers:

1. Plugin Host — discovers, loads, and manages plugin lifecycle
2. Caddy Manager — embeds Caddy as a Go library; manages vhosts and TLS
3. Site Registry — persists local sites to ~/.config/flock/sites.json
4. Wails GUI — native webview with Svelte frontend
