I recently started using my panel at home and felt lost without having such API’s. 

So I decided to change that:

✅ I built a lightweight REST and a GraphQL server for WinCC Unified.

✅ Implemented in Rust, they’re native, lightweight, single executables.

✅ Low memory and CPU footprint – thanks to Rust!

✅ With GraphQL, there is also support for tag & alarm subscriptions! 🔄

I always prefer using GraphQL — I find it tedious to constantly refer to separate REST documentation. But for some simple use cases, REST is perfectly fine.
