The free spending cap checklist

Pick a provider and tick off each step. Every step links to the provider's own settings or docs. Progress is saved in this browser only, so there is no account to make.

  Create a spend cap budget for Gemini API, Agent Platform (formerly Vertex AI), Cloud Run or Cloud Run functions, and set budget alerts for the rest.

  Set a monthly hard spend limit for your OpenAI organization or project, check auto-reload on prepaid credits, and see what each control does not stop.
• Anthropic 9 steps
  Set a monthly spend limit in the Claude Console for your organization or a workspace, check auto-reload on prepaid credits, and see what happens at the limit.

Some providers can only send alerts, not stop spending. The CapBrake relay can send those alerts to your browser or Slack. It is free in early access.
