Helicone is in maintenance mode. So I built the lightweight alternative I wanted.
A new open-source tool called TokenWatch has been developed as a lightweight alternative for tracking LLM costs, particularly for solo developers and small teams. The tool addresses the gap left by services like Helicone and Langfuse, which are either in maintenance mode or require complex self-hosting. TokenWatch offers features such as direct API calls to providers like OpenAI and Anthropic, local data storage using SQLite, an automated budget kill-switch, and cost attribution by feature and customer.
