New API

open sourceexplicit relation

New API is an open-source multi-tenant AI gateway that aggregates and distributes LLM API requests across providers like OpenAI, Claude, and Gemini through a unified proxy interface. It cross-converts requests into OpenAI-compatible, Claude-compatible, or Gemini-compatible formats, with built-in channel management, quota control, token-based authentication, and billing capabilities. Deploy via Docker with SQLite or MySQL for centralized model management.

New API is a free and open-source self-hosted AI API gateway and management system licensed under GNU AGPLv3. Users deploy it on their own servers to aggregate upstream LLM providers (OpenAI, Claude, Gemini), manage token quotas, and route API calls with zero software licensing costs.
