About

Percy is an all-in-one visual testing and review platform that automates visual quality assurance by capturing screenshots of your web, mobile, or component UI, comparing each snapshot against a baseline, and highlighting any unintended visual changes to ensure pixel-perfect consistency. The platform supports integration with popular test frameworks, CI/CD pipelines, and component libraries, enabling teams to capture snapshots at each commit, review diff overlays, approve changes, suppress noise from dynamic elements, and maintain stable visual approval workflows. Percy works across multiple resolutions, browsers, devices, and viewports, and offers features like cross-browser testing, full-page capture, branch-aware baseline selection, intelligent diff filtering, and built-in collaboration tools (approve, request changes, comment). With support for SDKs in major languages and frameworks (e.g., Playwright, Cypress, Storybook), teams can embed Percy into their existing test suites.

About

Stably is an AI-assisted browser and end-to-end testing platform for software teams. Users describe customer workflows in plain language or record them, then create reviewable Playwright tests and run them in Stably Cloud or their existing CI pipeline. The platform provides test planning, browser execution, screenshots, video replays, and trace data to help teams inspect results and investigate failures. It can identify test drift and propose repairs as web interfaces change, with updates reviewed through Git pull requests rather than applied silently. Stably supports QA professionals, product managers, and engineers who need to create, execute, and maintain browser-based checks for web applications, including release regression, checkout, authentication, forms, and other multi-step user journeys. Teams can connect test coverage to repositories, Jira tickets, and product documentation, and use Playwright code within familiar development workflows.
