Node-RED is also fairly popular in home automation circles, but it's a generic tool that can be used for different purposes.

For example, it can also be used to build chatbots.

Nodered is really awesome. I work in the Salesforce ecosystem where flow based programming is being pushed and adopted and always wish they would have adopted the nodered way of doing things.

+1 suprised it wasnt mentioned. Use it heavily in home assistant to connect up devices that were never designed to talk to each other to do some interesting things.
