https://mermaid.live/, makes you learn a new syntax that works like a markdown, but it’s pretty good. Especially, if you don’t like working with GUI applications.

Biggest difference is being able to execute INSTCMD commands, at least that was the main reason why I developed my own tool. Another less important differences are: older ARM support and since it’s written in Rust, it’s much more efficient in terms of resource usage. TBH, being that efficient only makes sense for very low-power devices.

Besides that, I don’t think you can go wrong with either project.
