LLMCap
Hard dollar caps on LLM API calls. When you hit ...,it stops
A reverse proxy that enforces hard dollar caps on LLM API calls. Change one line (base_url), set a cap — when you hit it, the next request returns 429 before the token reaches the provider. Money never spent. → Anthropic, OpenAI, Gemini, Mistral, Cohere → <35ms added latency → Live spend dashboard, audit logs Starter $19/mo · Pro $49/mo · 3-day trial.
Hey PH! I built LLMCap after seeing a $37,901 AWS Bedrock bill from a single misconfiguration posted on GitHub.
The problem with existing tools (Helicone, AWS Budgets) is they alert you AFTER the money is spent. LLMCap is a reverse proxy — when you hit your cap, the request returns 429 before the token ever reaches the provider.
The interesting engineering challenge: enforcing caps mid-stream without buffering the entire response. Happy to answer questions about the architecture!
