SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Running browser automation in headless mode hides every action from the user, making it hard to trust or debug what the AI is doing. This Skill launches a visible Chromium window with a live sidebar activity feed so you can watch every command in real time. ## Core Features & Use Cases - Visible Browser Launch: Starts GStack Browser (rebranded Chromium) in headed mode on port 34567 with anti-bot stealth patches so sites like Google work without captchas. - Sidebar Extension: Auto-loads a side panel showing a live activity feed and a chat tab where a sidebar agent executes natural-language browser commands. - Pre-flight Recovery: Kills stale browse servers and clears Chromium profile locks before connecting to avoid false "already connected" errors. - Use Case: Ask the AI to open the browser, then run a QA or design-review skill and watch every page load, click, and screenshot happen in the visible window. ## Quick Start Ask the AI to open the gstack browser and show you the side panel so you can watch its actions live.

Frequently Asked Questions about open-gstack-browser

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I open a visible browser that the AI controls?▼

Invoke the open-gstack-browser skill, which runs a setup check, cleans stale processes, and connects a headed Chromium instance on port 34567. You see every navigation, click, and snapshot happen in the visible window.

How do I watch AI browser automation in real time?▼

The skill auto-loads a sidebar extension into the launched Chromium. Pin the gstack extension from the puzzle-piece menu and open the side panel to see a live activity feed of every command the AI runs.

Does this affect my regular Chrome installation?▼

No. The skill launches Playwright's Chromium with its own profile under ~/.gstack/chromium-profile, leaving your regular Chrome untouched. It uses a persistent context with custom branding and stealth patches.

Why does the browser connection fail with an already-connected error?▼

Stale browse servers or leftover Chromium profile locks from a crash cause false connection conflicts. The skill's pre-flight step kills the old PID from .gstack/browse.json and removes SingletonLock, SingletonSocket, and SingletonCookie files.

What can I do from the sidebar chat tab?▼

The sidebar chat runs a child agent that executes natural-language requests in the browser, such as navigating pages, clicking buttons, filling forms, and reading content. Each task runs up to 5 minutes in an isolated session.
