Google AntiGravity vs Google Stitch

Desktop IDE vs web design tool. Antigravity installs on your machine and gives you a full coding environment: file explorer, terminal, debugger, extensions, the works. Stitch runs in your browser and gives you an infinite canvas for UI generation. You don't write code in Stitch (though you can export some). You don't design mockups in Antigravity.

Code vs mockups. Antigravity produces working software. You edit TypeScript, Python, React, whatever your stack is. The AI agents assist with implementation. Stitch produces visual designs: screens, layouts, component mockups. Its output is a starting point for design conversations, not production code.

Multi-model vs Gemini-only. Antigravity gives you model choice: Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS 120B. Switch models depending on the task. Stitch uses Gemini 2.5 Flash and Gemini 2.5 Pro under the hood. You don't choose or swap models; the tool handles it.

Multi-agent orchestration vs single-purpose generation. Antigravity runs parallel agents across editor, terminal, and browser surfaces. Its Manager/Editor architecture lets you plan at a high level and then execute across files. Stitch has a simpler interaction model: describe what you want, get variants, pick one, iterate. No agents, no orchestration, just prompt-to-design.

Deployment vs export. Antigravity doesn't have built-in deployment (you handle that yourself), but it produces deployable code. Stitch doesn't deploy anything either, but its output is design assets, not applications. Stitch exports to Figma for refinement and can generate starter front-end code, but that code is a beginning, not a finished product.

Audience. Antigravity is for developers who write code daily and want AI assistance in their editor. Stitch is for designers, product managers, and non-technical stakeholders who want to visualize ideas quickly without waiting for a developer to build a prototype.

Google Antigravity and Google Stitch are both AI tools from Google, but they serve completely different roles in the development workflow. One is for building software. The other is for designing interfaces.

Antigravity is a full desktop IDE (a VS Code fork) with multi-agent orchestration. You write real code in it, run terminal commands, test in a built-in browser, and manage complex projects with multiple AI agents working in parallel. It supports Gemini, Claude, and GPT models, and it's aimed at developers who want agentic coding capabilities in a familiar editor.

Stitch is a web-based UI design and prototyping tool. You describe a screen in natural language or upload a wireframe, and it generates UI mockups. You can iterate with variants, connect screens into prototypes, export to Figma, and grab starter front-end code. It's built for designers and non-coders who want to visualize ideas before anyone writes a line of code.

They're complementary products in Google's AI portfolio. Antigravity is where you build. Stitch is where you design.

Both tools offer genuinely useful free tiers, which makes sense since they're both still in relatively early stages of Google's AI product push.

Antigravity's Individual plan is free with unlimited tab completions, access to all models (including Claude and GPT alongside Gemini), and generous weekly rate limits. The AI Pro plan at $20/mo resets limits faster. Ultra at $250/mo removes the weekly cap. You can also buy $25 credit packs for burst usage.

Stitch is completely free right now. You get 350 standard generations and 200 pro generations per month. There are no paid plans yet. Google hasn't announced pricing tiers, which suggests it's still in the experimental/growth phase.

For budget-conscious teams, you can use both tools at zero cost. A designer prototypes screens in Stitch for free, hands off to a developer who codes in Antigravity for free. That's a complete design-to-code workflow with no subscription fees.

If you're a developer who writes code, Antigravity. It's a proper IDE with AI assistance. Stitch won't help you implement features, debug issues, or refactor existing code.

If you're a designer who creates interfaces, Stitch. It generates UI mockups from descriptions and images, supports rapid iteration with variants, and exports to Figma for your existing design workflow. You don't need to know how to code.

If you want to prototype an app idea fast, start with Stitch. Sketch out the screens, get the layout right, export to Figma or grab the starter code. Then move to Antigravity (or another IDE) to build the real thing.

If you need multi-model AI coding, Antigravity. Stitch doesn't let you choose models, and it's not a coding tool anyway.

If you're a product manager who needs to communicate ideas, Stitch. Turn your feature descriptions into visual mockups that your team can react to, without waiting for a developer to build a throwaway prototype.

If you need agents that can control a browser, terminal, and editor together, Antigravity. Its multi-agent architecture coordinates across surfaces in a way that's unique among IDEs. Stitch has no agent capabilities beyond basic prompt-to-design generation.
