Capped — AI Budget Alerts

About

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.
