llm-cost-guard
Stop runaway LLM API spend before it happens
Wrap your Anthropic, OpenAI, or Gemini client with guard() — it tracks token spend on every request and throws a hard stop before you breach your budget. Unlike billing alerts (delayed, non-blocking), llm-cost-guard sits in your code and kills the request before money is spent. Supports per-user limits, Slack/Discord webhooks, pre-flight cost estimation, Redis storage, and full TypeScript types.
Hey PH! Advik here, maker of llm-cost-guard 🛡️
Built this after accidentally running a Claude API loop on 847 items overnight with no limit set. Woke up to a ₹4,000 bill.
Anthropic's billing alerts are delayed and don't stop the request — they just email you after damage is done. So I built middleware that sits in your code and kills the request before it fires.
Would love feedback on:
- Which storage adapter to build next (Redis is planned)
- Whether LangChain integration would be useful for your stack
- Any providers missing from the pricing table
