New APIOpen-source LLM gateway unifying multiple AI provider APIs with routing, billing, and analytics

New API is an open-source LLM gateway that provides a unified interface for connecting to multiple AI model providers, including OpenAI, Anthropic Claude, and Google Gemini-style APIs. It acts as a central management layer that lets teams route requests across providers, control access, and track usage from one place. The project is aimed at developers, platform teams, and organizations that consume AI APIs at scale and want a single gateway rather than integrating each provider separately. By exposing OpenAI-compatible endpoints, it allows existing applications and SDKs to work with many backends without rewriting client code. Beyond basic proxying, New API focuses on operational concerns such as token-based quotas, billing and credit management, request auditing, and usage analytics. These features make it suitable for building internal AI platforms or reselling/metering access to multiple users or teams. As an open-source, self-hostable tool, it gives operators control over deployment and data flow, which can be important for cost management and compliance. It positions itself in the same space as other API gateways and aggregators like LiteLLM and One API, from which it derives. As with most self-hosted gateways, adopting New API requires infrastructure setup and ongoing maintenance, and the breadth of provider support and stability depend on community contributions.
