Percy
AI-powered visual testing that catches UI regressions on every commit.
About
Percy by BrowserStack is a visual testing and review platform that captures screenshots of web apps across browsers and viewports, compares them against baselines, and flags visual changes so UI bugs are caught before production. It plugs into CI/CD pipelines with integrations for GitHub, GitLab, Bitbucket, Jenkins, Storybook, and Figma.
In October 2025 Percy launched an AI-powered Visual Review Agent that the vendor says speeds review by 3x and filters out 40% of false positives like anti-aliasing and sub-pixel noise. A permanent free tier covers 5,000 screenshots per month, with paid plans from $199 per month.
What it can do
- Automated screenshot capture and comparison
- Visual AI Engine noise and false-positive filtering
- Visual Review Agent with change summaries
- Storybook and Figma integrations
- No-code visual monitoring via Visual Scanner
