Browse — Browser QA Tool

Overview

browse is a CLI tool for AI-agent-driven browser automation. It wraps Playwright behind a persistent daemon that listens on a Unix socket, so every command after the first cold-start (~3s) runs in sub-200ms. Session state (cookies, localStorage, auth tokens) persists across commands. Use it for QA verification, visual checks, form interaction, auth testing, and automated healthchecks.

Quick start

Just run any command — the daemon cold-starts automatically if it isn't already running.

browse goto https://staging.example.com    # navigate
browse snapshot                            # see page structure with refs
browse screenshot                          # capture the page
browse quit                                # shut down the daemon

First useful sequence: browse goto <url> → browse snapshot → browse screenshot.
