Google has just dropped a combo that no one saw coming. On one side, Stitch, the UI design tool powered by Gemini that transforms a simple prompt into a complete interface. On the other, AntiGravity, the agent-based IDE capable of coding, debugging, and deploying autonomously.

Connect the two via the MCP (Model Context Protocol), and you get an application production pipeline that practically runs itself.

Free, accessible with a Google account, and already functional as of February 2026. The Stitch + AntiGravity team-up allows you to go from a rough idea to a deployed application in under 30 minutes, without writing a single line of code by hand.

This isn’t science fiction. Developers and creators are already using this workflow to launch landing pages, dashboards, and fully-fledged mobile apps.

The question is no longer “is this possible?” but rather “how do we get the most out of it?”

Google Stitch: The Design Agent That Generates Interfaces in 60 Seconds

Stitch was quietly launched during Google I/O 2025 on May 20th, flying under most creators’ radar. Originally called Galileo AI in Google Labs, the tool has been rebranded and supercharged with the latest versions of Gemini.

The concept is simple: describe the interface you want in natural language, and Stitch generates a full design with ready-to-use frontend code.

Two modes are available. Standard mode uses Gemini 2.5 Flash for fast generations (up to 350 per month). Experimental mode runs on Gemini 2.5 Pro or even Gemini 3.1 Pro for more detailed results (50 generations per month).

Both are completely free; all you need is a Google account to access stitch.withgoogle.com.

What Stitch Can Do

The list of capabilities goes way beyond a simple mockup generator. Stitch produces HTML/CSS, React/Tailwind, and can export directly to Figma in a click.

The tool integrates Nano Banana, Google’s image generation model, which means every generated interface can include custom visuals without leaving the platform.

  • 3x Mode: generates three simultaneous variants of the same design for quick comparison
  • Multi-page generation: create several pages in one go (homepage, pricing, checkout, etc.)
  • Visual identity extraction: upload an image or paste a competitor’s site URL and Stitch extracts the style to apply it to your own creations
  • Annotation and targeted editing: select a specific canvas section to request precise changes
  • Customizable themes: change colors, corner radius, fonts directly from a dedicated panel

If you’re interested in the role of AI in UX design, Stitch is the most tangible example to date.

The tool doesn’t replace a senior designer, but it cuts out 80% of the repetitive work in layout and prototyping.

The December 2025 Gemini 3 Update

In December 2025, Google integrated Gemini 3 directly into Stitch. The result: higher quality UI generations and a new feature called “Prototypes”.

You can now link your various screens on the canvas to create a complete interactive prototype, with transitions and functional user flows.

No more Figma needed to test a flow—everything happens in the browser.

In early 2026, Stitch also introduced Hatter, an agent capable of handling multi-step design tasks, as well as an asset generator for the App Store (screenshots, descriptions, icons), and native MCP export to Cursor, Claude Code, and Gemini CLI.

Google AntiGravity: The Agent-Based IDE That Codes for You

AntiGravity was announced on November 18, 2025, alongside Gemini 3. It’s a heavily modified fork of Visual Studio Code, but with a radically different philosophy: here, AI isn’t just an assistant suggesting code.

It’s an autonomous agent that plans, executes, validates, and iterates on complex development tasks.

Google calls this the “Agent-First” approach. You give a directive like, “Refactor the login flow to support OAuth and check it against these design specs.” The agent does the rest.

Key Point: AntiGravity reached 76.2% on SWE-bench Verified, a benchmark measuring an AI’s ability to resolve actual GitHub tickets on production codebases. This is one of the highest scores on the market as of 2026.

The Two Workspaces

AntiGravity offers two complementary work modes. Editor View works like a classic IDE with code completion and inline commands—perfect for developers who want to stay in control.

Manager View (also called Mission Control) is the real innovation: a dedicated interface to launch and monitor multiple AI agents working in parallel on different parts of your project.

One agent handles design, another manages functionality, a third checks for bugs—and they don’t interfere with each other.

Each operates in its own workspace with automatic coordination. This is real multi-agent development, not a whitepaper concept.

The Browser Sub-Agent

AntiGravity includes a browser sub-agent capable of launching a Chromium instance. Thanks to the multimodal vision abilities of Gemini 3, the agent can literally “see” your web application as a user would.

It detects visual errors, responsive issues, and can even take screenshots to diagnose display bugs.

If you’ve ever worked with tools like Cursor AI, imagine the same thing—supercharged.

How to Connect Stitch and AntiGravity via MCP

The Model Context Protocol (MCP) is the bridge that connects Stitch to AntiGravity. Think of it as a universal remote: on one side, your designs in Stitch; on the other, your development environment in AntiGravity; and MCP as the thing that makes them communicate.

5-Minute Setup

Setup is now trivial thanks to the latest updates. Here’s how it works:

  1. Go to stitch.withgoogle.com/settings and create an API key
  2. In AntiGravity, click the three dots in the Agent panel, then “MCP Servers”
  3. Search for “Stitch” in the integrated MCP store and install it
  4. Paste your API key and save

Stitch is also available directly in the AntiGravity native MCP Store. One search, one click, and the connection is established—no JSON file setup required.

The Six Stitch Skills

Beyond MCP connection, there’s a set of skills you can install to supercharge the integration. These skills are hosted on an official GitHub repo and follow the open Agent Skills standard, compatible with AntiGravity, Gemini CLI, Claude Code, and Cursor.

  • Design MD: converts your ideas into a design file documenting layout, colors, and structure
  • React Components: generates modular React/TypeScript components from Stitch screens
  • Stitch Loop: the star feature; creates an autonomous loop where the agent generates, evaluates, and iterates on multiple pages automatically
  • Enhanced Prompt: refines your design prompts for more accurate results
  • Project Analysis: analyzes an entire Stitch project to extract patterns and recommendations
  • Video Walkthrough: generates video presentations of your Stitch creations

Installing is a one-command job: copy the GitHub repo URL, paste it into AntiGravity, and the agent automatically imports all the skills.

The Full Workflow: From Prompt to Deployment

Here’s what the process looks like in practice, as creators are already using it daily.

Step 1: Design in Stitch

You start with a descriptive prompt. For example: “Create a mobile ecommerce app for premium South African coffee, with a homepage, a product selection page, and a checkout.”

Stitch generates all three pages at once, with realistic images made by Nano Banana and a coherent design.

You then refine each page with targeted edit mode. Select the section you’re not happy with, request a change, and Stitch regenerates just that part. It’s quick and iterative—rarely more than 30 seconds per change.

Step 2: Transfer to AntiGravity

There are two options. Export as .zip (HTML + images), which you open directly as a folder in AntiGravity.

Or, the recommended method: transfer via MCP, where the AntiGravity agent connects directly to your Stitch account, retrieves the projects, and starts working.

The MCP command “list projects” shows all your recent Stitch projects with thumbnails. You pick the one to develop, and the agent takes it from there.

Step 3: Code and Deploy

AntiGravity transforms the Stitch designs into a functional application. The agent creates the file structure, codes the components, sets up routing, and even generates a design system document with the color palette, typography, and components used.

For deployment, the agent can push the code to GitHub and then connect it to Vercel for instant production rollout.

Every later change in AntiGravity syncs automatically to the live site. For those interested in AI-assisted website design, this pipeline is a major leap forward.

The Autonomous Loop: The Game-Changing Stitch Loop

The most spectacular feature of this integration is the Stitch Loop. This skill lets AntiGravity autonomously create multiple Stitch projects in parallel, each with its own pages and style, all running in the background while you do something else.

In practice, you can give a prompt like: “Create two projects in Stitch, one coffee shop site and one premium jacket site, each with three pages, using the visual style from this site.”

The agent fires up MCP creations, generates screens in Stitch, and codes the apps in AntiGravity. All this without using your credits, since generations go through Stitch (which is free).

One user built a habit-tracking app with authentication, a database, and deployment in 23 minutes thanks to this combined workflow.

While the agent works, you can open Manager View to monitor progress in real time—or just go grab a coffee.

The agent handles errors, retries failed attempts, and notifies you when everything is ready.

New MCP Tools: The Two-Way Feedback Loop

The latest Stitch MCP update added two tools that change the workflow dynamic.

Tool 1 – Edit Screens: Your AntiGravity agent can now request changes directly in Stitch. It’s no longer a one-way flow (design → code).

If the agent spots a design element that doesn’t work in code, it flags the needed change on the design side. This creates an automatic feedback loop between design and development.

Tool 2 – Generate Variants: The agent can generate multiple screen variants in Stitch automatically. Instead of creating five versions of a landing page by hand, prompt: “Generate three versions of the hero section—one focused on community, one on results, one on tools.”

The agent produces all three in Stitch, visible to the whole team. Designers, developers, marketers—everyone sees the same thing.

Stitch Alone vs. Stitch + AntiGravity: What’s the Difference?

Using Stitch on its own means a quick mockup in your browser—great for validating an idea in 30 seconds. But the exported code remains a static prototype.

With the Stitch + AntiGravity combo via MCP, you move from prototype to product. The agent codes the backend, integrates a database, adds authentication, and keeps iterating without copy-pasting files between tools. It’s the difference between a napkin sketch and a live production app.

For web agencies and freelancers already using AI plugins for Figma, the Stitch-AntiGravity integration offers a complementary pipeline that dramatically speeds up functional prototyping.

Pricing and Accessibility

Both tools are free as of February 2026. Stitch is part of Google Labs with monthly generation limits (350 standard, 50 experimental).

AntiGravity is in public preview with generous Gemini 3 Pro usage limits. No credit card required; a Google account is all you need.

AntiGravity is available on macOS, Windows, and Linux. It also supports third-party models like Claude Sonnet 4.6, Claude Opus 4.6, and open-source variants.

FAQ

What exactly is Google Stitch?

Stitch is an AI-powered UI design tool developed by Google Labs. It generates full user interfaces and frontend code (HTML/CSS, React/Tailwind) from natural language prompts. Launched at Google I/O in May 2025, it uses Gemini models for its generations.

Is Google AntiGravity just a code editor?

No. AntiGravity is an “Agent-First” IDE based on VS Code. Unlike a standard editor, it lets you launch autonomous AI agents that plan, code, test, and deploy applications. Its Manager View (Mission Control) allows you to supervise multiple agents working in parallel.

Is the Stitch + AntiGravity combo really free?

Yes, both tools are free as of February 2026. Stitch offers 350 generations per month in standard mode and 50 monthly in experimental mode. AntiGravity is in public preview with generous limits. Just a Google account required.

What is the MCP protocol and why is it important?

The Model Context Protocol (MCP) is an open standard that lets AI agents communicate with external tools. In Stitch + AntiGravity’s case, MCP acts as a bridge: the code agent can access Stitch designs, modify them, and create new variants right from the IDE.

Do you need to know how to code to use this workflow?

No. One of the major benefits of this combo is it’s completely prompt-based and works in natural language. Stitch designs, AntiGravity codes the app, and deployment can happen via Vercel in a few clicks. Creators with no technical background are already using it.

What types of projects can you create with Stitch and AntiGravity?

Virtually any type of web or mobile application: landing pages, e-commerce sites, analytics dashboards, SaaS applications, portfolios, productivity apps. Stitch Loop even lets you create multiple projects at once in different styles.

How does Stitch Loop work in practice?

Stitch Loop is a skill that automates creation in a loop. You give a brief (project type, page count, reference style), and the AntiGravity agent creates the projects in Stitch via MCP, generates the screens, and then codes the applications—all with no manual involvement.

Can you use AntiGravity with models other than Gemini?

Yes. AntiGravity natively supports Gemini 3.1 Pro and Gemini 3 Flash, but also Claude Sonnet 4.6, Claude Opus 4.6, and open-source models. You can switch models for different tasks.

Is the code generated by this workflow production quality?

The code produced is functional and deployable, but like with any AI generation, it may need adjustments. AntiGravity makes debugging easier with its Browser Sub-Agent, which detects errors automatically. The iterative process (prompt → error → correction) is normal and part of the standard workflow.

What’s the difference between exporting as .zip and using MCP?

Exporting as .zip downloads the HTML and image files to your computer to open in AntiGravity manually. MCP connects the two tools directly: the agent accesses your Stitch projects, pulls the designs, and iterates without any manual export. MCP is the recommended way for a seamless, continuous workflow.
