Detailed overview

BrowserStack Percy is a visual testing platform for detecting unintended user interface changes. It captures screenshots during automated test runs, compares them with approved baselines, and presents visual differences for review in pull requests or the Percy dashboard. Because Percy works with common browser automation and component testing workflows, teams can add visual checks alongside functional suites rather than maintaining a separate manual screenshot process. BrowserStack's broader platform can extend testing across browsers and devices, while Percy focuses on visual diffs, approvals, and reviewable build results. The service is useful for web applications, design systems, and component libraries where a small styling or layout change can affect many screens. Visual snapshots still require thoughtful coverage and human judgment about intentional changes. Available parallelism, retention, integrations, and browser or device access depend on the current BrowserStack plan.
