No, that's just a well-curated list. I am thinking along the lines of https://diskprices.com/ where you have all the characteristics/features mapped and can filter down using a faceted search (e.g. implemented using datasette) by what you need. For example, I know that if I need iOS Reminders integration, IFTTT has support for that but not n8n/make/zapier. And I think Make does not support Github integration with webhooks, only API calls. If you have a set of things in mind you'd like to integrate, picking the tool that supports a full combo OOB is a pain in the spreadsheet.
I have been running Huginn on an Ubuntu VM since Yahoo Pipes shut down almost 10 years ago.
I've tried out NodeRed and n8n over the years but they've been a huge let down in ease of manipulating multiple RSS feeds and web scraping -- my primary use case for Huginn. I tried Zapier and IFTTT as well, but the free tier didn't allow for what I wanted to do. Since I could do it just as well with Huginn, I decided to stick the more complex flows there also.
Once you figure out the workflow (setting up agents, and which agents suit which task), then it's fairly straightforward.
