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.
