Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.
It's an open source and we are working on its customization for the proprietary use. The other parts are ready. Since our developer is not available these days, we are in need of hiring a developer who is able to add the user management part. It's not so complicated. Please feel free to ask me if you have questions.
