|---|---|---|---|
| What it is | Generates real React Native (Expo) projects — actual component files and navigation stacks, not a webview wrapper — with Convex or Supabase for data plus built-in AI inference and image-generation APIs. It runs the build, creates your App Store Connect listing, and uploads it for you. | Browser IDE built on Code OSS with an App Prototyping agent that turns a prompt into a Next.js or React app wired to Firebase. Supports Flutter and React Native workspaces plus full Git access to the generated code. Google announced its sunset on 19 March 2026. | Rebranded from Create.xyz. Generates React and Tailwind web apps deployable to Vercel or Netlify, with 40+ prebuilt integrations and code export on every plan. Max adds parallel agents, a 1M-token context window, and visual QA driven by a computer-use agent that clicks through your app. |

| Pricing | Free (limited messages, 1 project) · Pro $20/mo (100 messages/day) · $50 / $100 / $200 and up | Free · 3 workspaces (10 with Google Developer Program, 30 Premium) · Blaze billing for App Hosting | Free tier · Pro $19/mo (20K credits) · Max $199/mo (220K credits) |
| Why builders pick it | The shortest distance from prompt to an app sitting in review on both stores, because it owns the build and submission step that normally eats a week. Source export unlocks at Pro. | Was the cheapest way to get a Gemini-built app sitting directly on Firestore and Firebase Auth with no credit meter anywhere. Only relevant now for finishing and migrating workspaces you already have. | The integration catalogue is the draw — Stripe, auth and third-party APIs land pre-wired instead of as prompts you babysit. Max's automated visual QA is rare at any price on this list. |
| Watch out for | The free plan caps you at one project and cannot export code — you need Pro to get the source out. Message caps, not compute, are the binding constraint on real work. | Shutting down. New workspaces and signups were disabled 22 June 2026, and the service shuts off 22 March 2027 with remaining data deleted. Google directs users to AI Studio or Antigravity; Firestore and Auth are unaffected. | Rebranded from create.xyz to anything.com, so older tutorials and links are stale. Credits do not roll over month to month, and it targets React web only — no React Native or Expo export. |
| How to wire it up | Apple Developer Program ($99/yr) and Google Play ($25 one-time) accounts are still required. | not logged | not logged |
