I have been successfully using Node-RED for quite some time now (https://nodered.org/) :) really like it so far, great tool to quickly add simple and complex health checks to your systems and automate various tasks that no necessarily deserve to have their own services. Kinda like your own FaaS platform (mine runs on an Intel NUC).

Luna looks great and I actually think I initially saw it and then I was looking for it but couldn't find it, ending up with Node-RED. I might give it a try, however I didn't see any mentions of how it integrates with Git :/
