visual regression

Autonomous QA tool that takes a URL, explores the app like a user, generates end-to-end tests, and files bug reports with screenshots and repro steps.

LayoutLens is an AI-assisted UI testing tool that combines natural-language visual checks with deterministic WCAG audits using axe-core and Playwright. It supports keyless accessibility scans, hybrid LLM-grounded checks, a Python API, and a CLI for running tests in CI.

SightDiff is a local visual proof tool for checking what an AI coding agent changed before you commit. It captures baseline screenshots, re-renders your app after changes, and shows a before/after diff sheet with changed and unchanged surfaces flagged.
