  Free and open source. A Mac app, or in your browser on Linux with npx agentbox-app,

Vitest and the Tiptap editor that only a new major version of each would clear.
The install worked if it exits without an error.

It starts on your machine and opens a tab. On Linux that open goes through xdg-open. Nothing is hosted: it listens only on 127.0.0.1, and the address carries a key that is new every run. Add --help to see the options. --no-open prints the address and leaves the browser to you.

The terminal is the one piece that is compiled while it installs, and on Linux that needs make and a C++ compiler. Without them the install leaves the terminal out, everything else works, and the command says so each time it starts. On Debian or Ubuntu, sudo apt install build-essential and install again.

From a checkout, build the screen once, then start it the same way. The install links the checkout's own command, so npx runs this copy rather than looking for agentbox on your PATH:

On Linux, npm install puts…
