one-api and fastapi-sdk
These are **competitors** — both provide unified API management and distribution systems for multiple LLM providers, with overlapping model support (OpenAI, Azure, Baichuan, Spark, Qwen, etc.) and similar deployment options, so users would typically choose one or the other rather than use them together.
