SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Fast, reliable QA checks and bug evidence collection are tedious to do manually. gstack provides a fast headless browser to automate site opening, interaction, diffing, and screenshot capture for QA cycles.

Core Features & Use Cases

  • Traverse pages, interact with elements, verify state, and diff before/after to spot regressions.
  • Take annotated screenshots and test responsive layouts, forms, uploads, and dialogs to capture evidence for bugs.
  • Use in workflows like opening deployments, dogfooding user flows, or filing bug reports with visual evidence.

Quick Start

Launch a QA session by opening a site and running a basic gstack QA task.
