Plexus is a unified API gateway that lets developers switch between AI providers like OpenAI, Anthropic, and Gemini without rewriting client code, while offering OAuth, quota tracking, and OpenAI-compatible endpoints. It’s built for engineering teams who need to manage multiple AI models efficiently, avoid vendor lock-in, and simplify integration. Its appeal lies in abstracting provider complexity into a single, drop-in interface that also handles authentication and usage monitoring.
