Pros
Pro Works online and offline

Cons
Con Saves files in browser's local storage
Local storage is limited and if the browser crashes the text can be lost.
Con Cannot be accessed while being offline
Even though the editor itself works offline, you need internet access to open the website and the editor.
Con Lacks a good integrated spell checker
Uses the built-in browser spell checker which may not be as good as spell checkers other editors have. Depending on the browser, of course.
Con Publishing to GitHub requires giving write access to repos
In order to publish documents to GitHub, StackEdit requires writing access to your repos, something which many people may not be comfortable with.
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.
