I built Lunar to make my day to day work on our AI gateway easier: basic testing of different providers, advanced testing of features like complexity router, and so on. Lunar allows you to easily switch across providers, gives you debugging tools (`/debug` to dump provider response headers, `/request` to dump the current prompt as a curl request, easy configuration with Lua, and more...).
You can use your OpenAI or xAI subscription on it (Anthropic also supported, but use it at your own risk, as it's against Anthropic's terms - I developed it as an experimente). API keys also supported.
Eager to know your thoughts! :)
