Category: infrastructure

Tags: llm, api-proxy, billing

Score: 6.7/10 (Innovation: 7, Technical: 6, Documentation: 5, Utility: 7)

Wattfare is a billing proxy for LLM APIs where end users pay for their own inference costs, shifting the financial burden from developers to consumers. It offers OAuth-like consent, per-app spending caps, and no provider key exposure, making it an innovative take on API monetization. The project is interesting for its potential to eliminate developer cost risk and enable freemium models without upfront funding.

Target audience: backend devs
