Dumpio

Dumpio is a desktop app for macOS, Windows, and Linux. You can download a prebuilt binary or run the app from source.

Download a build

Download the installer for your platform and run it:

• macOS – a .dmg file
• Windows – an .exe installer
• Linux – an AppImage

After installing, launch the app like any other program. No further configuration is needed — a default server is created on first launch.

Run from source

You need Node.js 18 or newer.

1npm install
2npm run dev

npm run dev starts the app in development mode with hot reload. For a production build of your platform, use:

1npm run build:mac
2npm run build:win
3npm run build:linux

First launch

When no server is configured at startup, Dumpio automatically creates a default one:

So the app accepts dumps immediately after startup. In the window you'll see an empty list with a short guide.

Verify the server is running

1curl http://127.0.0.1:21234/health

The response confirms it's running and reports the version:

1{ "ok": true, "version": "0.4.1" }

Alternatively, in Settings → Servers each row shows live status (running · N conn or stopped) and a Send test dump button that sends a sample log dump to the server.
