burn0-dev/burn0
Lightweight cost observability for every API call in your stack. Track LLM tokens, database ops, and external services from your terminal.
This tool helps developers understand and control the costs associated with their applications' API calls, including LLMs, databases, and other external services. It takes your existing codebase, monitors all outgoing API requests automatically, and then shows you in real-time what each call costs directly in your terminal. This is ideal for software engineers, engineering managers, or startup founders who need to keep their infrastructure expenses in check.
Use this if you are developing or managing an application that uses many third-party APIs and you need to clearly see where your money is being spent.
Not ideal if you need a comprehensive, enterprise-level observability platform that tracks more than just API costs, or if you don't use external APIs extensively.
