Use the best AI coding agents

Claude Code and Codex are among the most powerful ways to build software with AI. Infusion lets you use them in a simple app-building experience, without needing to manage terminals, files, environments or deployment yourself.

FrontendBackendDatabaseAuthFunctionsDeploy

Backend, database and auth included

Infusion gives your app the pieces it needs to actually work: frontend, backend, database, auth, backend functions and publish. You describe what you want, the agent builds, and the app is created inside a ready-to-use full-stack environment.

No credits to buy0

Bring your own subscription

Use the Claude or Codex subscription you already pay for. Instead of buying credits just to test ideas, you can keep building with the AI agent you trust most.

Publish like magic

Go from idea to live app in one flow. Describe your app, let Claude Code or Codex build it, refine it by chatting, and publish it to the web without leaving Infusion.

How it works

From idea to published app in one flow.

Nothing to install, no server to configure, no one to depend on. You connect your agent, describe your idea and the rest happens.
