How much Infusion costs. Start for free.
You build your app without paying anything. When you want to publish on your own domain, get more users or build more apps, you subscribe to Pro and choose the size of each app. All prices in US dollars.
Start free.

Pick the size of each app.
There are two layers: your plan sets how many apps you create and which features you get; the machine sets how big each app can get. On Free, every app runs on the Free machine; on Pro, you pick each app's machine and move up as it grows.

The user limit and the custom domain depend on the machine, not the plan. With Pro, an app on the Free machine still allows 2 registered users, including you, and has no custom domain.
What it costs in practice
Three common cases, with plan and machine already added up.
Your full app, with backend, database and login, running on its .infusion.cloud address. Up to 3 apps, no credit card.
Your site or app live with a custom domain and up to 10 registered users.
App with a custom domain, up to 1,000 registered users and a 10 GB database.
Prices in US dollars, per month. Visitors to public pages don't count as users.
An AI subscription is optional.
Every plan already comes with credits to build. If you already pay for an AI subscription, you can connect it and keep building without depending on credits.
Use the models you already pay for.
Build more.
Worry less.
Pricing questions
What people ask most before subscribing.
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.
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.
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.
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.
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.
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.
No. For now, all plans are monthly.
No. To create a Free plan account, you only need an email address.
Credit card.
