After a couple of months and volumes of ChatGPT queries, I released Mididash - a cross-platform, open source MIDI router with Lua scripting and a node based interface.

Features:
- Open source and cross-platform
- Hot plugging and replacement of MIDI devices
- MIDI monitoring and other pre-configured nodes
- Lua scripting
- Node based dashboard
- Performant and lightweight (built with tauri/rust)

Thanks for any help testing during this beta stage, I don´t expect many users (who uses MIDI routers anyway), still any help more than welcome.
Best,
