Describe your idea in chat and Lovable turns it into a working app or website
Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.

No-code AI regression and UI testing for web apps, straight from your browser
Capture clicks, typing, drag-and-drop, uploads, form submissions and navigation, then replay the whole scenario instantly without writing scripts.
AI-driven visual comparison detects subtle differences in layout, styling and rendered content between expected and actual UI states.
When element IDs or properties change, scripts fall back to alternate locators such as XPath, relative paths or element position to stay green.
Connect Sauce Labs, BrowserStack, LambdaTest or Testing Bot accounts to run the same recorded test on multiple browsers and platforms.
