SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Persistent, reliable browser automation for AI QA work: gstack provides a fast, persistent headless browser daemon that Claude Code can drive, enabling deterministic browser-based testing and dogfooding.

Core Features & Use Cases

Persistent headless browser: a long-lived Chromium daemon that preserves cookies, tabs, and session state across commands for repeatable testing.
Browser tooling suite: navigation, content extraction, interactions (click, fill, type, etc.), snapshot with refs, diff, annotate, and dialog handling.
Local QA + design dogfooding: verify flows, gather evidence (screenshots, diffs), and produce test artifacts across projects/workspaces.

Quick Start

Run the gstack browser daemon once, then drive it with browse commands to test a page or workflow.

FAQPage Schema

How do I run persistent headless browser automation for AI QA testing?▼

Persistent headless browser automation uses a long-lived Chromium daemon to preserve cookies and session state across commands, enabling repeatable QA testing and site dogfooding without losing context between interactions.

Does gstack work with Playwright for headless browser testing?▼

Yes, gstack uses a Playwright-backed server to drive a persistent headless Chromium daemon, providing reliable browser automation, content extraction, and interaction testing for multi-workspace projects.

Can I take screenshots and diffs during headless browser testing?▼

Yes, the browser tooling suite supports snapshot with refs, diff, and annotate functions, allowing you to gather visual evidence and produce test artifacts during QA validation workflows.

What is the best way to maintain session state across browser automation commands?▼

Using a persistent headless browser daemon maintains session state, cookies, and tabs across multiple commands, ensuring deterministic browser-based testing without needing to re-authenticate or reload context.

Do I need Bun installed to run the gstack browser daemon?▼

gstack implements a Bun-compiled binary for its Playwright-backed server, so the appropriate Bun runtime environment is required to execute the daemon and drive browser automation commands locally.
