Cloud credits

Cloud credits pay for the cloud computers your cloud threads run on. They are the only usage limit on every plan. Your AI usage stays on your own Claude or ChatGPT plan, or your own API key, with no markup, and local threads never use credits.

What uses credits

One thing uses credits: a cloud computer while it's awake. That's your agent working (reading code, running commands, installing, building, testing), plus the few minutes it stays awake after the agent finishes, before it pauses itself. A build or dev server that's still running keeps it awake too.

Every time a cloud computer starts, it uses at least 1 credit.

Everything else is free:

Credits per hour

Credits follow how long a cloud computer is awake, at a rate set by its size.

Cloud computer Credits
Paused 0
Standard (1 CPU, 2 GB memory) 100 an hour
Larger (2 CPUs, 4 GB memory, Zest and up) 200 an hour

Credits are counted by the second. A computer pauses itself after 5 quiet minutes, so a thread you've stopped looking at soon stops using credits.

Tip: the larger computer uses credits twice as fast. Keep it for big builds and long test runs, and use the standard one for everything else.

When credits refill

Plan credits refill in full once a month, all at once. Monthly plans refill when your next payment goes through. Yearly plans refill on the same day each month as the day you subscribed. Unused plan credits don't carry over to the next month.

Plans and credit packs

Need more? Buy 5,000 credits for $10 on any plan. Bought credits are used only after your plan's credits run out. They don't refill, and they last 12 months. See pricing.

What happens at 0

Your cloud threads pause until your credits refill or you buy more. Running out deletes nothing: each thread keeps its history and its computer, and carries on where it stopped. Local threads keep working.

We let you know before that: a note in the app when a fifth of your plan's credits are left, a warning at a twentieth, and an email at each step.

Questions

Do subagents use extra credits? No. Subagents run inside their thread's cloud computer, so they only use the credits that computer uses while it's awake.

Do automations use credits? Each cloud run uses credits like any other thread. An automation with a check script skips runs when there's nothing to do, and a skipped run starts no computer and uses none.

Why did my credits go fast? Usually one of these: several agents running at once (each has its own computer), the larger computer (twice the rate), or a dev server or watcher keeping a computer awake.

Does storage use credits? No. Files, history and paused computers are free.
