Vanszs/VansRouter ? reverse-engineered prompt

Build me a local AI router app called VansRouter that I can run on my machine and use with tools like Claude Code, Cursor, Codex, Cline, and Copilot.

I want a simple dashboard where I can add and manage AI providers, copy an API key, and point my coding tool to a local OpenAI compatible endpoint like http://localhost:20128/v1. The app should automatically route requests to the best available model, fall back when one provider hits a limit, and let me use free or cheap options when my main subscription runs out. It should also save tokens by shortening or compressing tool output when possible, so I don’t burn through limits so fast.

Please make it easy to start locally, and if you need to check any current provider docs or setup details, look them up online. Keep it lightweight, reliable, and focused on helping me keep coding without interruptions.
