Percy by BrowserStack is a visual regression testing tool for catching UI bugs. Compare its free and paid plans, features and top alternatives.
Percy is a visual review and visual regression testing platform that captures screenshots of an application's UI during automated test runs and compares them against an approved baseline to catch unintended visual changes. It was originally built by Perceptual Inc., founded in San Francisco in 2015, and has been owned and operated by BrowserStack since its acquisition in July 2020.
Rather than relying on developers or QA testers to manually eyeball UI changes across browsers and screen sizes, Percy automates the comparison and surfaces only meaningful visual diffs for a human to review and approve, integrating directly into CI/CD pipelines.
Percy supports cross-browser and responsive visual testing, capturing screenshots across multiple browsers and viewport sizes to catch layout issues specific to certain devices or resolutions. It integrates with popular frameworks and CI tools including Cypress, Playwright, Selenium and Storybook.
The platform provides a visual review workflow where teams approve or reject detected diffs directly in pull requests, along with build history, team collaboration features, and, as part of BrowserStack, access to real browser and device infrastructure for more accurate rendering.
Percy's Free plan includes 5,000 screenshots per month with unlimited users and projects, making it accessible for small teams or side projects to start visual testing at no cost.
The Professional plan, priced around $149 per month billed annually (or $199 billed monthly), includes about 25,000 screenshots per month and a year of build history, while the Enterprise plan offers custom pricing with SLAs, compliance documentation and dedicated support for larger organizations.
