A cap on your API bill.
Capped watches what you spend on OpenAI and Anthropic. It tells you at 80%, 100%, and 150% of your monthly cap — quietly, once, before the invoice does.
Made in Stockholm · No. 01
A read-only admin key. OpenAI and Anthropic both publish an organization key that can only read usage — it can't make calls, can't see prompts, can't spend money. Paste it once. Nothing else leaves your browser.
One number, one month. Set your cap in dollars. Capped runs quietly in the background. No dashboards. No tabs. No daily emails summarising what you already know.
A nudge before the bill does. One desktop notification at 80%, one at 100%, one at 150%. Pro now links a paid Stripe subscription to this browser, and browser-closed alerts are the next layer we're shipping.
