OneAPI Pro
An enterprise-grade AI API gateway, built as an extended fork of one-api, that adds subscription plans, active-active clustering, and precise billing for reselling or managing access to multiple model providers.
OneAPI Pro is a self-hosted gateway that sits in front of multiple AI model providers and exposes them through one API, aimed at organizations rather than the smaller relay-station deployments the original one-api is often used for. It rebuilds one-api's architecture to add subscription plans, active-active cluster deployment, and precise, per-request billing.
It ships a Go backend and a Vue 3 admin console, is distributed as prebuilt statically linked binaries for Linux, Windows, and macOS or built from source, and includes multi-host and decentralized cluster deployment options alongside a single-host manual deployment.
It is written in Go.
