Like the author of that article, I had never heard about Huginn until just now, but when IFTTT went down the shitter for me (around 2018) was about the same time I started using Home Assistant. I found that HA had every one of the service connections available that I used to use through IFTTT, so I naturally just re-implemented all of my flows as automations. HA has only added capabilities since those earlier days. It's not just for "home" automation.
If you're interested in more graphical representations of your automations, HA can have NodeRed as a plug-in.
