JustSong

JustSong is a Chinese indie publisher whose single public offering, One API, addresses the fragmented landscape of large-language-model services by acting as a lightweight, self-hosted gateway. Written in Go and distributed as a single binary or Docker image, the program lets developers consolidate API keys from OpenAI, Azure, Anthropic, Google Gemini, and a dozen domestic Chinese providers into one standardized endpoint. Typical use cases include SaaS startups that need to switch or load-balance between vendors without touching client code, academic labs that pool limited free credits from multiple accounts, and on-premise enterprises that want to meter, cache, or throttle employee access to generative AI. Administrators create channels, assign token budgets, set per-model rate limits, and monitor live usage through a built-in dashboard; end users consume a unified OpenAI-compatible interface, so existing libraries or front-ends require only a base-URL change. The system supports channel weighting, automatic failover, request/response logging, and user groups, making it equally suitable for internal prototyping and external commercial redistribution. One API is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always pulling the latest release and allowing silent batch installation alongside other tools.
