Every local project, one place to run it. For macOS, Linux and Windows.

localhost app (getlocalhost.app) is a free, open-source desktop process manager for local development: it starts, stops and watches all your dev servers, workers and databases from one window instead of terminal tabs. It runs your own commands, such as npm run dev, uv run or cargo run, with no Docker or containers required; Compose services can be one of them. Native on macOS, built with Tauri for Windows and Linux. A GUI alternative to pm2, foreman and tmux for local dev. It also has an MCP server, localhost mcp, so AI coding agents (Claude Code, Cursor, Codex) run the same Services.

localhost remembers how each of your local development projects runs, and lets you start, stop and watch all of its Services from one place, instead of a row of terminal tabs.

A Project is a folder. A Service is one long-running command in it: pnpm dev, uv run fastapi dev, docker compose up postgres, cargo run. localhost doesn't care what the command is: it runs it in your shell, keeps its output, knows when it is up, and stops its whole process tree when you ask.

• One place for every project: Start All / Stop All, Dependencies between Services (the API waits for the database), one merged log of every Service.
• Ports that make sense: a Service counts as Running once its Port accepts connections. If the Port is taken, localhost says by whom and can start the Service on the next free one. The Ports view lists everything listening on your machine, whoever started it.
• Environment without .env juggling: variables on the Project, on each Service and in Environment Profiles (Development, Testing, …). Any variable can be a Secret, kept in your system's secret store.
• Set up in seconds: point it at a folder and it suggests Services from package.json scripts, Compose files, Python apps and Cargo binaries. You review every suggestion; nothing is applied silently.
• Keyboard first: a command palette, a shortcut for every action, arrow keys across the window. Screen readers, light and dark, reduced motion.
• Coding agents included: Claude Code, Cursor, Codex and other MCP clients start, stop and inspect your Services through localhost mcp instead of a hidden shell. The agent and the app share one background core, so what the agent starts shows in the app, with its logs. See Coding agents (MCP).
• Updates that ask first: a check at launch and every 6 hours, a notice in the sidebar, and Restart to Update stops your running Services only after asking. See Updates.
• Your other computers too: a dev box you rea
