Building with the agent is pay as you go.
Every account starts with $10 of credit, no card needed, and gets $29 more, once, when the first month of a paid plan is paid. What Claude does for you, in Effortless Loops and on a project's Rules tab, is charged to it by usage as each turn finishes, and you see each one on your account page; credit also pays for hosting beyond what your plan includes. Add credit any time from $10 or set it to top itself up. On any paid plan, you can bring your own Anthropic key instead and pay nothing here for Claude.
Open Loops →What you pay for, and what you never do.
- Do I need a card to start?
- No. It is free to try: build, export and preview a project without one.
- What do the paid plans change?
- The Loops Runner, the machine that builds your project with the agent: how many hours a week it runs for you, how big it is and how long it waits before it sleeps. Starter, $29 a month: 20 hours a week, 1 core · 3 GiB; Builder, $59 a month: 30 hours a week, 1.5 cores · 4 GiB; Pro, $89 a month: 40 hours a week, 2 cores · 6 GiB. Need more in a month? 10 more hours are $8. Run as many projects at once as you like: each runner counts its own time. Every paid plan also runs Loops on your own machine and can use your own Anthropic key. You upgrade from inside the app, whenever you want.
- What happens when the month's hours run out?
- Your runners stop until you buy more hours (10 for $8) or the next month starts. Nothing is charged by surprise, and your projects stay exactly as they were.
- What happens if I go back to Free?
- Your projects, rulebooks and everything they generated stay yours. Your Loops Runner's hours and Claude come from your credit again.
- What do paid seeds cost?
- Each seed shows its own price and license before you add it. Browse them on Seeds.
- Can I take everything with me?
- Yes. Download any project, or your whole account as a spreadsheet, at any time. A license governs future runs of a tool, never what it already made.
