Why
Why both tiers are $0
We are doing one thing right now: making the product worth using daily.
The public pool is subsidised by us and deliberately small (20,000 tokens/day): enough for a real task, not enough for heavy use. Heavy users bring their own key, so the cost sits with the model provider and we just provide the runtime. When the product earns a price, we will add a subscription for higher concurrency and longer history — no pre-sales and no announced prices before that.
Over quota
What happens when the pool runs out
It degrades, it does not stop: you get a prompt to add a key, and nothing is lost.
Once the daily quota is spent, new runs are refused with a clear message. Existing sessions, messages and sandbox files are untouched. Adding your own key restores service immediately, no need to wait for the next day.

Where the numbers come from
The numbers on this page match platform settings; changing the quota changes this page.
Quota, concurrency and retention are read from live platform settings, not marketing copy. These are the free limits as of November 2026 and may change; changes land in the changelog first.
Run one real task first. Then decide whether it is worth paying for.
No credit card to sign up, and bringing your own key costs nothing extra.
