LLM Killswitch & Spend Guard

LLM Killswitch & Spend Guard is a self-hosted spending protection layer for OpenAI API applications. It sits between your app and OpenAI, reserves worst-case request cost before forwarding, reconciles actual usage afterward, and blocks requests when your budget can't safely accommodate them.

What you receive: Source code, deployment guide, and documentation. You deploy it into your own Cloudflare account — we never see, store, or access your requests, prompts, API keys, or usage data.

• Hard spending limits — requests blocked before reaching OpenAI when budget is exhausted
• Worst-case cost reservation before each request is forwarded
• Actual usage reconciliation after each call
• Streaming support
• Discord & Telegram threshold alerts
• Status endpoint — inspect budget state without a dashboard
• Self-hosted, zero data shared — runs entirely in your Cloudflare account

One-time purchase. You deploy it — we don't host or touch your data.
