localhost:

localhost vs tmux, tmuxinator

tmux keeps terminal sessions alive, on any server. localhost shows every dev server’s state, Port and log in one window, and stops whole process trees.

A terminal multiplexer: panes and windows in one terminal, in sessions that outlive it. tmuxinator describes a project’s panes in a YAML file.

Where tmux, tmuxinator win

  • Sessions survive closing the terminal and dropped SSH connections, on any server.
  • Each process gets a real terminal, so interactive prompts and full-screen tools work. localhost uses pipes, not a terminal.
  • Everything stays in the terminal, with no app to switch to.

Where localhost fits better

  • Every Service’s state at a glance (Running, Failed with a reason) instead of reading panes.
  • Stop ends the Service’s whole process tree, every time.
  • Native on Windows, with Projects on Windows itself or inside WSL.

localhost is a free, open-source desktop app that runs your own commands, no Docker required, and isn’t a production or remote-server dashboard. Install it, start with the quick start, or read the guides.

Install localhost for macOS

Two quick steps, usually under a minute.

  1. Drag it to Applications

    Open localhost-0.3.0.dmg and drag localhost to Applications.

    Download localhost-0.3.0.dmg

    Or install it with Homebrew, which also puts the localhost command in your terminal:

    brew install --cask marcellosso/tap/localhost

    Or download it from Terminal, which macOS doesn’t block, so you can skip step 2:

    curl -fLO https://github.com/marcellosso/localhost/releases/download/v0.3.0/localhost-0.3.0.dmg && open localhost-0.3.0.dmg
  2. Open it the first time

    localhost isn’t notarized by Apple yet, so macOS blocks the first launch once:

    1. Click Done in the warning.
    2. Open System Settings › Privacy & Security and scroll to Security.
    3. Click Open Anyway, and confirm with your password or Touch ID.

    Or run this in Terminal, then open localhost:

    xattr -dr com.apple.quarantine /Applications/localhost.app

macOS 15 or later · Apple silicon or Intel

  1. Run the installer

    Open localhost_0.3.0_x64-setup.exe. It installs for your user only, no administrator rights needed.

    Download localhost_0.3.0_x64-setup.exe
  2. Get past SmartScreen

    The installer isn’t signed by a known publisher yet, so Windows says “Windows protected your PC”:

    1. Click More info.
    2. Check that the file is localhost_0.3.0_x64-setup.exe.
    3. Click Run anyway.

Windows 10 or 11 · x64 · WSL 2 for Projects in WSL

  1. Download your package

  2. Install it

    From the folder you downloaded it to:

    sudo apt install ./localhost-app_0.3.0_amd64.deb
    sudo dnf install ./localhost-app-0.3.0-1.x86_64.rpm
    chmod +x localhost-app_0.3.0_amd64.AppImage && ./localhost-app_0.3.0_amd64.AppImage

    Secrets need a Secret Service (GNOME Keyring, KWallet). On stock GNOME the tray icon needs the AppIndicator extension.
