Autonomous AI-powered software testing that eliminates maintenance and accelerates release cycles.

The visual testing and review platform for high-velocity software teams.

Percy, acquired by BrowserStack, is the industry-standard visual regression testing platform that automates the process of identifying UI changes across web and mobile applications. Unlike traditional pixel-by-pixel comparison tools, Percy utilizes a sophisticated DOM-snapshotting architecture. It captures the DOM and CSS assets of a page, then reconstructs and renders those assets in its own controlled cloud environment across multiple browsers and screen resolutions. This methodology eliminates 'flakiness' caused by local font rendering or GPU variations. In the 2026 landscape, Percy has integrated AI-powered 'Smart Diffing' which distinguishes between intentional design changes and layout breakage, significantly reducing manual review time. Its positioning is focused on the 'Shift-Left' testing movement, allowing developers to catch UI bugs at the Pull Request level before they reach production. The platform scales from individual developers to global enterprises, providing a centralized hub for designers, developers, and QA engineers to collaborate on visual quality through integrated workflows with GitHub, GitLab, and Bitbucket.

Explore all tools that specialize in ui/ux qa. This domain focus ensures Percy delivers optimized results for this specific requirement.
Captures the actual DOM and CSS instead of just a screenshot, allowing for flexible rendering in Percy's cloud browsers.
A proprietary rendering pipeline that ensures 100% consistent browser environments for every build.
Distributes snapshot rendering across thousands of concurrent browser instances in the Percy cloud.
Native mobile app visual testing supporting iOS and Android via Appium.
Automatically ignores dynamic content like dates, video players, or scrolling elements.
Tracks visual baselines across different Git branches and merges baseline updates automatically.
Direct integration with Storybook and other component libraries for isolated testing.
Create a Percy account and project via the BrowserStack dashboard.
Install the Percy CLI and relevant SDK (e.g., @percy/cypress, @percy/playwright) via npm/yarn.
Configure your PERCY_TOKEN as an environment variable in your local machine or CI server.
Integrate the 'percySnapshot' command into existing test scripts.
Run your test suite using 'percy exec -- [test command]' to capture initial baseline snapshots.
Link your repository (GitHub/GitLab) to Percy to enable PR status checks.
Push a code change that affects the UI to trigger a new Percy build.
Access the Percy dashboard to review visual diffs generated between the baseline and current build.
Approve or reject changes within the Percy UI to update the baseline for future tests.
Configure Slack or Microsoft Teams notifications for real-time build status updates.
