At Google I/O 2025, the company unveiled Stitch — an AI-powered design assistant that lets developers generate frontend code and user interfaces with just a few words or an image. It’s Google’s latest play in the rapidly expanding world of AI-assisted, or “vibe,” coding.

According to Google, Stitch is an AI-powered tool to help application builders generate high-quality user interfaces for mobile and web apps, and easily export them to Figma, or directly access the frontend code. It uses some of the latest AI models from Google DeepMind.

Stitch is available for free of charge with certain usage limits. Each user receives a monthly allowance of 350 generations using Flash mode and 50 generations using Experimental mode. “Please note that these limits are subject to change,” says Google.

Stitch is designed to streamline the early stages of app and web design. Prompt it with a phrase like “photo-sharing app” or upload a rough sketch, and Stitch will spit out HTML and CSS code to match. Users can pick between Google’s Gemini 2.5 Pro or the faster, more lightweight Gemini 2.5 Flash model to power their workflows.
