SmartUI
By TestMu AI. Category: Visual AI testing. Homepage
TestMu AI's documentation describes SmartUI as a visual regression testing service for web and native mobile apps. It adds snapshot calls to existing Selenium, Playwright, Puppeteer, Cypress, WebdriverIO, Appium, Espresso and XCUI suites through SDKs or a CLI, and compares screenshots against baselines. Setup is documented for GitHub Actions, GitLab and Travis CI. A SmartUI agent skill works with Claude Code, GitHub Copilot, Cursor, Gemini CLI and Codex CLI. The vendor, formerly LambdaTest, renamed itself TestMu AI on 12 January 2026, and SmartUI kept its name.
