TOKENOMY

Tokenomy is an advanced AI token calculator and cost estimator built for developers working with LLMs like GPT-4o and Claude. Before you make a single API call, it predicts your token usage and dollar costs down to the cent. Available as a VS Code sidebar, CLI tool, and LangChain callback, Tokenomy helps development teams ship confidently by catching expensive prompts early, optimizing token efficiency, and keeping your OpenAI and Anthropic spend under control. Because nobody should be surprised by a four-figure API bill at the end of the month.
