Infusion uses Claude Code and Codex to power a simple prompt-to-app experience, with backend, database, auth, and one-click publishing included.
Lovable made app building magical. Infusion brings that same magic to Claude Code and Codex, so you can build with the world's best AI coding agents using your own subscription, without dealing with terminals, setup, infrastructure or deployment.
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.
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.
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.
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.
Nothing to install, no server to configure, no one to depend on. You connect your agent, describe your idea and the rest happens.
Bring your own account and choose the AI coding agent you want to build with.
Connect your account. Your subscription, your models.
Start with a prompt, a product idea, or a rough concept of what you want to create.
Claude Code or Codex creates the app inside Infusion, with backend, database, auth and deploy already part of the environment.
Ask for new pages, features, fixes, backend logic, auth rules, data transformation and improvements.
Deploy the app from the same place, without managing infrastructure or deployment setup.
Iterate using your own AI subscription, without constantly worrying about app-builder credits.
Replit's billing shifted to 'effort-based' and, with Agent 3, bills spiked. One user reported spending in a week what used to last nearly a whole month.
Cursor swapped the flat plan for a usage budget and many users burned their quota in just a few prompts. The CEO admitted they hadn't handled it well and apologized. The company refunded affected users.
On paid plans, leftover tokens expire within two months. On the free plan they don't even roll over: the cap is 300K a day. Bought but didn't use them? Gone.
Every message burns a different number of credits, and hosting arrives on a separate invoice. The surprise comes at month's end.
Reviews repeat the pattern: the agent fixes one thing, breaks another and revisits a bug it had already solved, draining credits along the way.
Usage billing can exceed your subscription with no preset limit. You're the one who has to pull the brake.

Most AI app builders make you think about credits while you are still exploring. Infusion lets you build with your own Claude or Codex subscription, so you can focus on the product instead of counting generations.
Illustrative credit-billing scenario. Real, sourced cases in the section below.
Use the models you already pay for. Build more. Worry less.
Building is always free and you use your own AI subscription. Pro unlocks unlimited apps and workspaces, team collaboration and a custom domain.
What everyone asks before building their first app.
Infusion is a prompt-to-app platform that turns Claude Code and Codex into a single place to build serious full-stack software. You describe what you want, the AI agent builds the app inside Infusion, and the whole workflow comes built in: frontend, backend, database, auth, versions, deploy and one-click publishing.
Everything from MVPs and startup products to robust business software: SaaS, internal tools, client portals, dashboards, AI tools, marketplaces, operational systems and even products that could grow into entire companies. The point isn't toy demos; it's one place to build serious full-stack software with AI.
It's one flow: connect your Claude or Codex access, describe the app, let the agent build it in a ready full-stack environment, refine it by chatting, manage versions and deploys, and publish with one click, all from the same place. No jumping between agent, terminal, repo, hosting, database, auth and deployment.
Because you build with the AI agent you already trust and pay for. The agent's work runs through your own subscription, while Infusion handles the app-building, the workflow and publishing around it. That way you're not spending builder credits just to keep exploring ideas.
No. You describe what you want in plain language and the AI agent builds the interface, backend and logic. Infusion is designed to make powerful coding agents easy for nontechnical builders. Technical users get a faster loop and can open the code whenever they want.
Lovable made prompt-to-app building simple and accessible. Claude Code and Codex are powerful coding agents. Infusion sits between the two: it keeps the simple builder experience but lets you build with Claude and Codex power, on your own subscription, inside a real full-stack workflow.
Yes. Every app is born on its own .infusion.cloud URL and, on the Pro plan, you point a domain you already own with a simple CNAME. The app goes live under your brand.
Yes. Infusion is meant for serious, production-oriented software: startup products, internal systems, enterprise workflows and mission-critical tools. Whether a specific app is production-ready still depends on its complexity, security, compliance, data model, integrations and testing.
Infusion is the easiest way to turn Claude Code and Codex into full-stack web apps.
