@hyperlunk I'm not sure it really matters which engine you use if it doesn't process the markdown in the same way and understand the obsidian plugins.
@vertis @hyperlunk It's fiddly, but there's a variety of markdown parser plugins that try to replicate Obsidian behaviour.
I haven't tried, but 11ty seems like it has the advantage that it supports the very large number of markdown-it plugins, whereas Jekyll by default uses kramdown.
