LLMCap is described as 'Reverse proxy that enforces real-time, dollar-based spending caps on LLM API calls. When you hit your cap, the next request returns 429 — the token is never consumed and money is never spent' and is an app in the ai tools & services category. There are more than 10 alternatives to LLMCap for Web-based, SaaS, Docker, Self-Hosted and Kubernetes. The best LLMCap alternative is Langfuse, which is free. Other great apps like LLMCap are Helicone, AI Security Gateway, RapidClaw and Spanlens.
