Antigravity: from product concept to a real app that saves data
Cofounder Live now uses the Google Antigravity SDK so Theo can take a live product concept and turn it into a real, deployable app — not just a prettier preview.
What’s new
- Antigravity coding worker — Theo launches coding agents that generate a working app (API + UI + Dockerfile)
- Live build view — watch agents write files in real time, then reopen the build anytime from Real app builder
- Open live app — preview the generated app directly inside Cofounder Live
- Durable memory — preview apps save through Firestore-backed
/api/memory, so entries survive refresh - Save/load verification — after each build, we POST then GET to confirm persistence before calling it done
- GitHub delivery — when ready, the real app can ship as a PR to the deliveries repo
Why it matters
Before, Cofounder Live could go from idea → landing page → product concept.
Now it can go one step further: idea → working app with real storage.
Try it
- Open Cofounder Live
- Build a product concept
- Hit Antigravity in Real app builder
- Save an entry in the live app, refresh, and confirm it’s still there
Built with Gemini, Vertex AI, the Antigravity SDK, Cloud Run, and Firestore.
