Overview & launch

For the complete documentation index, see llms.txt

The viewer is your home base: browse scenarios, run them, watch each step live, and debug failures — all locally.

Launch

Terminal window
npx @unotest/web viewer

It starts a localhost HTTP + WebSocket server and opens your browser. Set UNOTEST_VIEWER_NO_OPEN=1 to start without opening a tab. Your agent can also launch it via the open_viewer MCP tool.

What it is

  • Local-only. No cloud, no account. It reads run artifacts from unotest/.runs/ and your scenarios/helpers/collections from disk.
  • Read + run. Browse and run; results stream live over WebSocket.
  • Single source of truth. Breakpoints and variables are files on disk, so the CLI, the agent and the viewer all agree.
