Gstack
Skill Verified ActiveFast headless browser for QA testing and site dogfooding. Navigate pages, interact with elements, verify state, diff before/after, take annotated screenshots, test responsive layouts, forms, uploads, dialogs, and capture bug evidence. Use when asked to open or test a site, verify a deployment, dogfood a user flow, or file a bug with screenshots. (gstack)
To provide AI agents with robust, low-latency browser automation capabilities for testing, QA, and development workflows.
Features
- Fast headless browser automation
- Interactive element navigation and manipulation
- State verification and diffing
- Annotated screenshots and responsive layout testing
- Form testing, file uploads, and dialog handling
- Cross-browser cookie import and authenticated session testing
Use Cases
- Testing user flows like login, signup, and checkout
- Verifying deployments and checking production sites
- Dogfooding new features end-to-end
- Filing bug reports with visual evidence and console logs
Non-Goals
- Replacing the agent's judgment with automated decisions
