{"slug":"best-llm-cost-tracking-tool","title":"Best LLM cost tracking tool","question":"What are the best tools for tracking and controlling LLM API costs and token spend across providers?","verdict":"As of 2026-07-14, ChatGPT, Claude, Gemini and Grok collectively rank LiteLLM #1 for llm cost tracking tool on ModelsAgree — a unanimous pick. The models' case: Best overall value: one OpenAI-compatible gateway across 100+ providers with self-hosting, detailed spend attribution by key/user/team/tag, virtual keys, per-tenant. The models' main caveat: Operating the proxy, database, pricing metadata, and access controls is real infrastructure work. The strongest alternative is Helicone — Simple proxy/gateway with excellent real-time cost dashboards, per-user/key attribution, caching for savings, and accurate pricing across major.
