Con No mobile app
You can port Roam to Hermit, but there is no offline capacity.
Con No established pricing model, this could get expensive later
Rumored to be upwards of $30/month
Con No offline mode
The information can be accessed on the browser offline, but you cannot edit it.
Con Very expensive pricing model, no 'free' tier
For what still feels like beta-software, it's pricing model is very expensive in comparison with competitors that generally offer free tiers for example.
Con Forces you to edit with markdown, rather than wysiwyg
This issue is made worse by super basic formatting bugs, like if you want to for example unbold some text with control/cmd-b, it rather double-bolds it (e.g. it becomes bolded text), making the non-wysiwygness even more messy.
Con No vim mode
Con Database storage rather than files
This makes it a little less simple to work with (also has benefits).
Con Interface can be confusing
There is a fair amount of flexibility to the interface but it can also become confusing, especially when some parts are not necessarily simple to use. Most of the basic features nevertheless are intuitive.
Con Not markdown
It will import and export markdown but it does not store content as markdown. This isn't necessarily a problem if you don't need it.
Con Synchronization requires use of Trilium's sync server
This can be problematic to set up unless you have a web server that will support the requirements of this.
