Capped — AI Budget Alerts
Extension Actions
- Live on Store
Set a monthly cap for OpenAI and Anthropic spend. Get local alerts before the invoice surprises you.
HOW IT WORKS
1. Paste a read-only admin key from OpenAI or Anthropic. These keys can only read usage — they can't make API calls, can't see prompts, can't spend money.
2. Set a monthly cap in dollars.
3. Capped syncs hourly and fires a single desktop notification when you cross 80%, 100%, and 150% of your cap.
Free plan runs entirely in your browser. Your keys are stored in chrome.storage.local and never sent to our servers. Nothing reaches us unless you subscribe to Pro.
PRO ($9 / month) — optional
Cloud polling plus alerts via Slack, email, and SMS, so the nudge reaches you even when Chrome is closed.
PROVIDERS SUPPORTED
- OpenAI (/v1/organization/costs — requires an organization admin key)
- Anthropic (/v1/organizations/cost_report — requires an organization admin key)
Gemini and AWS Bedrock are on the roadmap.
WHAT CAPPED IS NOT
- Not an observability platform. No prompt logging, no trace viewer, no eval suite.
- Not a request proxy. It never touches your API calls.
- Not a replacement for your provider's own spend limits.
It is one simple thing: a cap, a cap line, and a nudge when you cross it.
