What is Stitch?
Stitch is a Google Labs experiment that designs user interfaces from plain language. You describe an app, a mood or a business goal, or drop in a sketch, screenshot or URL, and it produces mobile or web screens you can refine by chatting or by voice. It began as Galileo AI, which Google brought in, and was announced at Google I/O in May 2025.
On 18 March 2026 Google rebuilt it as an AI design canvas: an infinite board that holds images, text and code, a design agent that keeps track of the whole project, an agent manager for exploring several directions at once, linked screens you can play as a prototype, and DESIGN.md, a markdown file that carries a design system between Stitch and coding tools. It can also pull a design system from any website.
Designs export to Google AI Studio and Antigravity, and Stitch has an official MCP server, SDK and skills so coding agents can use it directly. It is free, for users 18 and over wherever Gemini is available.
Is Stitch worth it?
Before an app exists, someone has to draw it. If you are a founder or developer without a designer, that usually means a blank Figma file, an afternoon of nudging rectangles and a result that still looks homemade.
Stitch does the first draft for you. Type "a calm budgeting app for students, three screens" or paste a screenshot of something you like, and you get polished screens you can adjust by chatting with it. Link the screens and press Play and you have a clickable prototype; Stitch will even guess the next screen from where you click.
The March 2026 rebuild made it more than a toy. A design agent now remembers the whole project, you can explore several directions side by side, and DESIGN.md lets you hand the same colours, type and spacing to a coding agent. The MCP server means Antigravity or any other coding agent that speaks MCP can ask Stitch for screens without you copying anything. Investors took it seriously enough that Figma's share price fell 12% over two days after the announcement, according to press coverage.
The catch: it is a free experiment, and it behaves like one. Google does not publish the limits. Reviewers report daily credits, about 400 design and 15 redesign credits as of April 2026, with a simple screen costing around 3 credits and a five-screen flow 11, but there is no way to pay for more and the allowance has changed several times. Two people cannot edit the same canvas at once. Google's developer forum filled with reports in October 2026 of projects that would not load, credits stuck at zero and designs rendering as unstyled HTML.
The privacy terms deserve a look before you upload a client's work. Stitch does not have a plain-language data page of its own that we could find, and Google's other Labs tools let human reviewers read a sample of what you submit and keep reviewed items for up to 18 months.
Our take: Stitch is the sketchbook, not the studio; use the free credits to find a direction in an hour, then finish the work somewhere with version history, comments and a contract.
Where it earns its place
A solo founder preparing a seed pitch
Show what the app will look like before hiring a designer
Describe the product and its users, explore two or three directions in the agent manager, and link five screens into a clickable prototype for the deck, within one day's free credits.
A front-end developer on a small agency team
Turn a client's brand website into consistent app screens
Point Stitch at the client's site to pull its design system, generate screens, then export the DESIGN.md file so the coding agent building the React app uses the same tokens.
A product manager at a 200-person SaaS company
Explain a new onboarding flow to engineers before design capacity frees up
Sketch the flow on paper, upload a photo, and refine the generated screens by voice. Keep it to non-confidential features, since Google's Labs terms allow human review.
Before you commit
- Setup
- Sign in at stitch.withgoogle.com with a Google account (18 or older); the first screens arrive within minutes and need no install.
- Integrations
- Export to Google AI Studio and Antigravity, React or HTML and Tailwind code and Figma according to third-party reviews, plus an official MCP server, SDK and skills repository for coding agents.
- Data and privacy
- Not published as a Stitch-specific policy we could find; Google's Labs tools such as Flow allow human reviewers to read sampled interactions and keep reviewed items for up to 18 months.
- Limits
- Daily credits reset at midnight UTC, with costs shown only after generation; no simultaneous multi-user editing; Labs status means features and quotas can change or end without notice.
What’s good
- Free, with roughly 400 daily design credits reported
- Prompts, screenshots, URLs and voice all work as starting points
- Clickable prototypes and DESIGN.md hand-off to coding agents
- Official MCP server and SDK for Antigravity, AI Studio and other agents
What’s not
- Google does not publish limits, and you cannot buy more credits
- No real-time collaboration on one canvas
- Frequent outages and rendering bugs reported in October 2026
- No Stitch-specific data policy; Labs tools allow human review
Best for
Founders, developers and product managers who need believable app screens or a prototype quickly and have no designer yet.
Stitch alternatives
Stitch: common questions
- Is Stitch worth it?
- Stitch is the best free way to get a first draft of an app's screens, and nobody should mistake it for a design tool you can run a team on. We rate it 3.8 out of 5.
- How much does Stitch cost?
- Free during the Labs beta, with daily credit limits that Google does not publish; third-party guides report 400 design credits and 15 redesign credits a day as of April 2026, resetting at midnight UTC. No paid plan and no way to buy more.
- What are the downsides of Stitch?
- Google does not publish limits, and you cannot buy more credits; no real-time collaboration on one canvas; frequent outages and rendering bugs reported in October 2026; no Stitch-specific data policy; Labs tools allow human review.
- Who is Stitch best for?
- Founders, developers and product managers who need believable app screens or a prototype quickly and have no designer yet.
- Is Stitch safe for company data?
- Not published as a Stitch-specific policy we could find; Google's Labs tools such as Flow allow human reviewers to read sampled interactions and keep reviewed items for up to 18 months.
- What are the best Stitch alternatives?
- The closest alternatives we have reviewed are Figma, v0 and Canva.
