About Infusion
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.
Founders, startups, enterprises, internal teams, software houses, agencies, operators, marketers, students and vibe-coders who want to build serious software with AI without becoming full-time infrastructure managers. It's just as useful for technical teams who love Claude and Codex power but want a faster loop to build, version, deploy and publish.
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.
Everything from MVPs and startup products to robust business software: SaaS, internal tools, client portals, dashboards, AI tools, 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.
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.
No. Infusion gives more people a practical way to build software with AI and gives technical users a faster path from idea to a working app. Developers use it to prototype, iterate, review and ship faster, not to be replaced.
How it works
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.
The whole app-building layer: frontend, backend, database, auth, backend functions, project structure, versions and deploys, preview, refinement and one-click publishing. So you focus on what the product should do, not on wiring up infrastructure first.
No. Infusion is built for full-stack apps, with frontend, backend, database, auth, backend functions and publishing, because genuinely useful software needs much more than generated UI screens.
Usually not. Frontend, backend, database, auth, versions, deploys and one-click publishing are already included, so most people never touch GitHub, Vercel, Supabase or environment variables. Advanced teams can still plug in external tools when they want custom infrastructure.
Yes. Infusion is built for iteration, not just first drafts. After the first version, you keep asking for new pages, UI changes, backend logic, auth rules, database changes, integrations, fixes and improvements through the same conversation.
You can, especially if you enjoy managing repos, environments, hosting, database, auth, secrets, logs and deploys. Infusion is for builders who want the power of a coding agent but prefer all of that to already be part of the builder, instead of wiring it up by hand every time.
Infusion focuses on full-stack web apps, but they're responsive from the start, so they run great on phones and tablets straight from the browser. Native App Store or Play Store builds aren't the focus today.
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.
By standardizing the prompt-to-app workflow around Claude and Codex, agencies, software houses and repeat builders go from idea to working software much faster. Instead of rebuilding the same setup for every client or internal project, the team focuses on what matters: requirements, iteration, versions, delivery and operations.
Yes, on the paid plans. The app can have AI agents that run tasks inside it. The Free plan doesn't include agents. How many agents run at the same time depends on the app's machine: Lite 1, Starter 10, Scale 50.
Credits and AI subscription
You get credits included in your plan. On Free they renew every day, up to the monthly limit; on Pro you get 100 per month, to use at your own pace. When they run out, you can keep building with your own Claude or Codex subscription.
On Free they come back the next day, up to the monthly limit. On Pro they come back when the month turns. If you don't want to wait, connect your Codex or Claude Max subscription: from then on its limits apply, not ours.
No. The app stays live and your customers keep using it normally. Credits are what the AI uses to build or change the app. Using the finished app doesn't use credits. When credits run out, only building and editing stop, until your credits come back or you connect your AI subscription.
No. You get credits on us, and you can also connect your own subscriptions.
Codex from the entry plan up. For Claude, you need the Max plan: the smaller plans run out after a few requests.
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.
Pricing, plans and publishing
You can start for free. The Pro plan is $20 per month and includes 100 monthly credits, plus the infrastructure your apps use. For teams, the Teams plan has custom pricing: everything in Pro, a shared workspace, CX + Support and security scans. Your AI subscription is separate: you connect the one you already use, such as Claude Max or ChatGPT (Codex), and keep paying your AI provider directly.
No. For now, all plans are monthly.
No. To create a Free plan account, you only need an email address.
Credit card.
Anyone who logs in to the app counts as a registered user. Visitors to public pages, like a booking page that doesn't require login, don't count toward the limit.
Because the user limit is set by the app's machine, not by the plan. On the Free machine, each app allows 2 registered users, including you (the owner), and Pro doesn't change that. To get more, switch the app's machine: Lite ($3.99 per month) for 10 registered users, Starter for 1,000, Scale for 50,000.
The app stops accepting new sign-ups. To get more users, switch the app to a bigger machine.
Yes. On the Free plan, up to 3 apps. On Pro, up to 50.
You pay for one Pro plan, not one per app, plus the machine price of each app on a paid machine. Example: Pro with 2 apps on the Lite machine costs $27.98 per month ($20 for Pro plus $3.99 for each Lite). An app on the Free machine adds nothing.
Yes, on Pro, as many as you want. The Free plan has 1 workspace.
Yes. On Pro, you choose the machine for each app and change it as the app grows.
If you move the app to a bigger machine, the change takes effect right away and you pay only the difference for the days left until your next invoice, as a separate charge. If you move to a smaller machine, the change takes effect on your next invoice. All paid machines are on the same monthly invoice, which runs from the day you subscribed to Pro.
It starts the moment you switch the app to a paid machine, whether the app is published or not. While the app stays on the Free machine, there is no machine charge.
Yes, on the Pro plan.
Yes. Every app is born on its own .infusion.cloud URL and, on the Pro plan with a Lite machine or higher, you point a domain you already own with a simple CNAME. The app goes live under your brand.
No. You register the domain with any provider you like and point it to Infusion.
By email, at [email protected]. Email support is part of the Pro plan.
On the Pro plan, support is by email and prioritized: you get a first reply from a person on our team within 1 business day. Support hours are Monday to Friday, 9 a.m. to 6 p.m. Brasília time.
Shared workspaces are part of the Teams plan. Teams includes everything in Pro, plus a shared workspace, CX + Support, security scans and optional consulting. Teams has custom pricing: talk to us.
