Tokenwise: An LLM proxy tool that helps developers track and reduce API spending
By

More flour than flavour. There's a bagel in here, just not much of one.
Summary
Tokenwise is a lightweight LLM proxy tool designed for makers and small teams to monitor and optimize their API spending on large language models. The creator, Theo, shares his personal frustration with rising LLM costs across multiple SaaS projects and tools like Claude Code, Cursor, and Codex. Tokenwise acts as an OpenAI-compatible baseURL that learns from real requests, identifies where users are overpaying, applies fixes with one click, and verifies savings in real dollars using quality checks on actual traffic rather than public benchmarks.
