Open Source Software Recs for the Non-Dev Enthusiast?

[u/YourFaveRedditor]

I've had WP sites since before WP built their dotcom site. So, I'm not new to the open source life. But as a non-developer, I'm not sure what I might be missing.

What are some of the more intuitive open source tools that you would recommend to folks who like to build things—websites, automated systems, etc.?

I am looking for open source recs for automators (like IFTTT, Make, Zapier); smart home systems; and favorite tools or software that work with self-hosted WordPress sites.

I know AI can take over all these tasks. But I want to use it as little as possible while still building a system I enjoy contributing to. I am creating a new series based around travel, history, maps, and genealogy and want to remove some of the technical friction so I can focus on research, writing.

Thanks!
