Describe what you want in plain English. AppNGen generates website designs you can preview and refine in seconds — free. When you're ready, it plans the architecture, builds it with an autonomous coding agent, and hands you a live preview.

How it works
Three steps from prompt to production.
You stay in the conversation. The pipeline does the rest.
02
Plan & build
The architect designs the system and batches work into sprints. An autonomous coding agent implements each one and gates it with tests.
03
Preview & ship
Every build gets a live preview URL backed by real git history. Iterate by chatting — changes rebuild and redeploy on the spot.
Capabilities
Everything between "what if" and "it's live."
💬
Conversational spec
Refine scope by talking. The analyst captures user stories and acceptance criteria so the build matches your intent.
🧭
Architecture & planning
C4 design, contracts, and a dependency-aware sprint plan generated before a line of code is written.
🤖
Autonomous agent
A coding agent implements each sprint, runs your gate command, and retries until it's green.
⚡
Live previews
Each project ships to a real, shareable preview environment the moment a build passes.
🔐
Config & secrets
Per-project environment and secrets, stored in a vault and injected at build and preview time.
🌿
Git-backed
Every project is a real repository with commit history — inspect, branch, and take the code with you.
