SStitch by Google

Stitch is the only design agent on this list that costs nothing. Google Labs gives it away with a standard Google account, and an April 2026 review of its limits counted 400 design credits a day, where a five-screen app used about 11. The tool comes from Galileo AI, a UI generation startup Google acquired in 2025, and when Google turned it into an AI-native design canvas in March 2026, Figma’s stock was down about 4% on the day Fast Company covered the news.

It is best for founders, product managers and designers who want to explore many interface ideas quickly and then carry the best ones into Figma or code. It is still a Labs product, so daily caps cannot yet be raised by paying, limits have changed several times, and it runs on standard Google accounts rather than a managed team plan. We rate it 8.5/10 on our scale. We have not used Stitch ourselves; this review is based on Google’s announcements, news coverage and a published review of its credit limits.

Origin, I/O 2026 Updates and the Credit System in Facts

The facts below come from news coverage of its origin and updates, Google’s I/O 2026 press materials and a detailed review of its credit system.

Two numbers matter most for a buyer. The first is zero: no seat fee, no card, no contract. The second is the daily cap. At about 3 credits for a simple edit, 400 credits cover roughly 133 small changes a day, and at 11 credits per five-screen app, about 36 full app drafts. That is more than most people need for exploration, but it is a hard ceiling with no paid overflow.

The stock move is a sign of how seriously the market takes free AI design tools, not proof that Stitch replaces Figma. Fast Company noted that Figma still dominates professional design workflows, and Stitch’s own export path runs into Figma.

An Infinite Canvas in the Browser Since March 2026

Stitch runs in the browser. Since March 2026 it has been built around an infinite canvas, similar in feel to Figma, where every iteration of a project stays in one space instead of a chat history.

Starting a Design

• Give it context: type a prompt, or add images, sketches or code to the canvas as reference.
• Pick a model: faster Gemini 3 Flash or the more capable Gemini 3.1 Pro, which uses more credits, according to an April 2026 review.
• Generate flows: Stitch builds complete user flows, such as onboarding or checkout, rather than isolated screens, an approach carried over from Galileo AI.
• Refine: edit by prompt, select specific screens to change, or ask the agent for alternatives such as another color palette or menu layout.

The Design Agent

The March 2026 update added a design agent built for design reasoning. According to Fast Company, it can give real-time critiques, interview a user to design a landing page and make live changes on request. Users can talk to it by voice and use it as a sounding board. An agent manager organizes tasks when agents work on several ideas at once, so a user can compare directions side by side. At Google I/O on May 19, 2026, Google went further with real-time design, where users guide and reflow layouts while the Stitch Agent builds them.

Design Systems, Prototypes and Export

Design rules can be imported and exported, including as DESIGN.md, a markdown file written so that other AI agents can read a product’s design system. Google Labs product manager Rustin Banks said designs can be reused across Stitch projects. An instant prototype mode turns a project into an interactive app preview. When a design is ready, it exports to Figma with organized layers and Auto Layout, to React, to HTML and CSS with Tailwind, or through MCP for coding agents.

Designers Still Decide What the Product Should Be

Stitch drafts and iterates; it does not decide what the product should be. Galileo’s founders framed the approach as automating 60% to 70% of UI creation with designers finishing the screens. In practice, someone still needs to check accessibility, align components with a production design system, write final copy and hand off to engineers.

No Paid Tier, Just Daily Limits on a Google Account

Stitch has no paid plans. It is free with a standard Google account and no credit card. The limits below are from Banani’s April 2026 review of Stitch’s credit system; Banani makes a competing design tool.

Credits reset at midnight UTC and cannot be purchased. Usage is visible under Profile and Stitch Settings. The chosen model affects how many credits each action uses, and the reviewer found that redesign actions drew from standard daily credits rather than the separate redesign allowance. Click-and-drag prototyping did not consume credits in that review.

Time Spent and the Tools You Still Need Around Stitch

Because Stitch is free, the real cost is time and the tools around it. The usage figures below come from the April 2026 review; the scenarios are our own illustrations.

• A founder sketching an MVP: at about 11 credits per five-screen app, 400 daily credits allow around 36 full drafts a day at no cost, far more than a single product needs.
• A designer iterating on one flow: at about 3 credits per edit, the daily allowance covers roughly 133 small changes before the midnight UTC reset.
• A product team handing off to Figma: Stitch is free, but a team that finishes work in Figma pays for Figma seats, reported at $16 per full seat a month on annual Professional billing.

Over a 30-day month, 400 daily credits add up to 12,000, though unused credits do not carry over. The main constraint is the cap itself: on a deadline day there is no way to buy more.

Stitch Compared With v0, Figma Design Agent and Lovable

Stitch sits between design and code tools. It produces design screens first and exports both ways, while v0 and Lovable produce working apps and Figma’s agent edits design files directly.

Use Stitch to explore and decide, then move the chosen direction into Figma or a code agent. v0 and Lovable are the better picks when the deliverable must run, and Figma’s agent when a team’s design system already lives in Figma. See our AI agents for design guide and the free AI agents list for more.

Founders Without Designers and PMs Testing Ideas

• Founders without a designer: complete flows from a prompt give a credible first version of an app at no cost.
• Product managers: quick, clickable prototypes help test an idea with users before design or engineering time is spent.
• Designers exploring directions: the agent manager and infinite canvas make it easy to compare several concepts at once.
• Developers using coding agents: DESIGN.md and MCP export give coding agents a design system and screens to build from.
• Students and freelancers on a budget: the free allowance covers a lot of practice and client concept work.

Enterprises Needing SSO, Access Controls and Contracts

• Enterprises that need governance: Stitch is a Labs experiment on standard Google accounts; teams that need SSO, role-based access and contracts are better served by paid tools such as v0 Enterprise or Figma.
• Teams with heavy daily volume: the daily cap cannot be raised by paying, which can block work on deadline days.
• Brand and marketing designers: Stitch designs software interfaces, not social posts, print or brand assets; Canva AI or Lovart fit better.
• Teams that need production code: exports give a starting point, but v0 or Lovable produce apps that run and deploy.
• Designers who want full control inside Figma: Figma’s own agent edits files and components directly.

Changing Limits and No Paid Credit Top-Ups Yet

• Changing limits: Stitch moved from 550 monthly generations to daily credits within a year. Treat current limits as temporary.
• No paid overflow: when the daily allowance runs out, work stops until midnight UTC.
• Model choice affects credits: Gemini 3.1 Pro uses more credits per action than Gemini 3 Flash.
• Labs status: Google Labs products are experiments; plan for features to change, and keep exported copies of important work in Figma or code.
• Data and account type: Stitch runs on a standard Google account, so companies should check their own policies before uploading unreleased product designs.
• Human finishing: generated screens need accessibility checks, real content and alignment with production components.

Real-Time Design With the Stitch Agent at I/O 2026

• On May 19, 2026, at the Google I/O developer keynote, Google introduced real-time design with Stitch, letting users guide and reflow layouts as the Stitch Agent builds.
• In April 2026, a review of Stitch 2.0 limits reported 400 daily design credits and 15 daily redesign credits, replacing the earlier 550 monthly generations.
• On March 18, 2026, Google Labs turned Stitch into an AI-native design canvas with a design agent, agent manager, voice and DESIGN.md, Fast Company reported.
• In May 2025, Google acquired Galileo AI and relaunched it as Stitch, giving Galileo users 30 days to move over.

An Easy First Step for Exploring App Interfaces

For exploring app and website interfaces, yes, and the price makes it an easy first step. Stitch scores 8.5/10 on our scale: excellent on cost and setup, solid on autonomy for a design tool, with room to grow on team governance and public ratings. Its design agent, agent manager and Figma and code export cover the jump from idea to a concept a team can discuss.

Treat it as the front of the funnel. Use Stitch to generate and compare directions, then finish the chosen one in Figma or hand it to a code agent such as v0. Teams that need guaranteed capacity, admin controls or contractual data terms should look at paid tools, and everyone should keep exported copies of work they care about. The good news is that trying it costs only time: a team can run a week of real design questions through Stitch, export the best results to Figma and judge whether the drafts saved more time than they took to clean up.

Galileo AI’s Fate, Figma Export and DESIGN.md

Is Google Stitch Really Free?

Yes. Stitch has no paid plans and needs only a standard Google account and no credit card. As of April 2026, reported limits were 400 design credits and 15 redesign credits a day.

What Happened to Galileo AI?

Google acquired Galileo AI in 2025 and relaunched it as Stitch by Google. Galileo users were given 30 days to move to Stitch.

Can Stitch Export Designs to Figma?

Yes. Designs export to Figma with organized layers and Auto Layout preserved, according to an April 2026 review. They can also export to React, to HTML and CSS with Tailwind, or through MCP.

What Is DESIGN.md in Stitch?

DESIGN.md is a markdown file that describes a design system in a form AI agents can read. Stitch can import and export design rules in this format, so a coding agent can follow the same colors, type and styles.

What Is Outside Stitch’s Scope Today?

It does not produce deployable apps, and it designs software interfaces rather than brand or print assets. Daily credits cannot be topped up, and it runs as a Labs experiment on standard Google accounts.
