Start free.
Scale predictably.

Free includes $5, Pay as you go includes $10, and Pro includes $300 of shared usage each month. Tool calls, builds, evals, publishing checks, bandwidth and managed-chat output draw from one pool. Allowances reset on your organization's monthly cycle and do not roll over.

Free won’t incur overage charges. If metered activity pauses, wait for the next monthly reset or enable paid usage in Billing to keep running within a budget you choose. Your previous usage carries forward; adding a card alone does not create a charge.

Yes. In Billing, add a card, review the usage rates and choose an additional-usage budget, including $0. Paid usage has no subscription fee and includes Free features, higher project and team limits, adjustable spending limits, and $10 of monthly usage. Usage above the allowance is billed at the published rates within your budget.

Owners and admins can set an additional-usage budget in Billing. A $0 budget is valid. Metered activity pauses when the allowance and budget are used; plan features remain available. In-flight usage can slightly exceed the budget. Platform fees are separate.

Rates are graduated per organization and monthly usage cycle. Only usage inside each band receives that band's rate; earlier usage is not repriced. Tool calls count, while discovery requests such as listing tools do not. Bandwidth and other meters are charged separately.

Free, Pay as you go, Pro and Enterprise include external MCP connections. Each connected MCP counts as one project. Connecting it does not create hosting or build charges; services you use, such as evals and publishing checks, remain metered.

Existing packages remain available to their current customers with their attached pricing, allowances and terms. Billing identifies them as legacy plans. You can choose Pro through checkout; Enterprise plans are arranged with our team.
