LunarWerxs/DevWebUI

bun install && bun run dev
Download devwebui-windows-x64.exe from Releases (Windows prebuilt)

Usage

• •First launch scans once for .devwebui files; afterward add projects via 'Add project', dropping a folder/.devwebui file on the Windows launcher, or `devwebui open <path>`.
• •Define one .devwebui file per repo listing processes (id, name, command, cwd, port, env, autostart, links, companion); processes can also be edited in the GUI.
• •Register the MCP server in your client with DEVWEBUI_URL=http://localhost:4000 to drive the same daemon the GUI uses.
• •Use the CLI (devwebui start/stop/status/list/start-all/mcp) or DEVWEBUI_PORT to point at another daemon.

Key features

• ✓31 MCP tools covering projects, processes, logs and the de-duplicated error log.
• ✓Port-conflict rescue: detects a taken port, tells you which process holds it, and frees it on request.
• ✓Runtime-aware launches that follow each project's lockfile; Windows desktop shortcuts and tray app.
• ✓Full i18n (English base) with light/dark themes; local-first, open source, no account required for core use.

Best for

Developers who run many local dev servers and want a clickable dashboard plus agent automation over one shared daemon.

Caveats

• ⚠Prebuilt tray/desktop experience is Windows-focused; macOS/Linux tray is on the roadmap.
• ⚠Optional settings sync requires a LunarWerx Connections account and is off by default.
• ⚠Sends an anonymous install ping (opt-out via DEVWEBUI_NO_PING=1); core functionality needs no cloud.
• ⚠MIT licensed.
