Google Stitch
Hard to argue with free: Stitch produces usable first-draft UI screens and working frontend code with a straight path into Figma. It remains a Labs experiment - quotas, no support guarantees, and the standalone Galileo AI product it grew from was already shut down once.
Pros
- Free, with a real Figma handoff path
- Multimodal input: text, sketches and screenshots
- Gemini 2.5 Pro backs the higher-quality mode
- No install - runs on a Google account in the browser
Cons
- Monthly generation caps per mode
- Experiment status means features and limits can change without notice
- No API for automation
