The Problem
The Claude API bills by token. That's obvious. What isn't obvious is how fast costs accumulate across parallel sessions, long conversations, and cached prompts — until you open the invoice at the end of the month and do the math backwards.
The Solution
ClawCost is a lightweight dashboard that tracks API usage in real time, breaks down costs by session and model, and gives solo developers and small teams the visibility they need to build responsibly. Free tier for individuals, Pro tier for teams, fully self-hostable.
ClawCost shows you what your Claude API usage is actually costing — by session, by feature, by model — before the bill surprises you.
Open source. MIT license. Can be deployed in under five minutes on any Node.js host.
