My project is a flow based programming editor with a flowrunner library. It can be run standalone but I am also working on a web variant which could evolve in a saas model. Currently I have flowrunner implementations in various languages: javascript/typescript, php, rust/wasm , c#. It can be used for learning, building webapps and native mobile apps, data exploration/charting, realtime debugging. I still have to choose my main focus area. It is in active development but fare from completion.
