Tokenwise

Tokenwise is a drop-in proxy that gives you full visibility and control over your LLM spending. Connect your app or coding agents (Claude Code, Cursor, Codex) by swapping a single base URL. Tokenwise then logs every call — cost, tokens, latency — and surfaces exactly where your money is going. The dashboard lets you slice data by model, app, or agent, so you can see which endpoints are burning cash.

What makes Tokenwise stand out is its optimization engine. Instead of just showing you numbers, it identifies specific leaks: oversized system prompts loaded on every call, cache misses on repeated queries, or expensive models handling work a cheaper one could do. Each recommendation comes with a one-click fix, a quality replay check against your own baseline, and a projected savings figure. You can apply the change, preview it on live traffic, or ignore it. Nothing changes silently. Tokenwise also supports multiple providers through a single proxy endpoint — you can route calls to OpenAI, Anthropic, Google Gemini, Groq, DeepSeek, and more without changing your SDK.

This tool is built for engineering teams and product teams running AI features at scale. If you're spending hundreds or thousands a month on API calls and suspect you're overpaying, Tokenwise gives you proof and a fix. It's especially useful for teams using AI coding agents, where uncontrolled call volume can quietly balloon costs. The setup takes minutes, and the first savings often appear within the first week.
