Pros
Pro Outline-style hierarchy with zoom

Cons
Con Doesn't work well in mobile browsers
The functionality of the mobile version of the site is a bit limited, while new features have been added such as the ability to move lines of text, even that is limited on Android to only being functional on Chrome.
Con Offline desktop app requires Chrome
The offline desktop requires installing Google Chrome first before the WorkFlowy app can be installed. This is not good news for non-Chrome users especially users who frequently uses Firefox or Safari as their default browsers, in which Chrome app also suffers memory leak and battery issues.
Con Inconvenient interface
Notes automatically collapse, making them unreadable without user interaction. You cannot view multiple long notes at once.
Con No public API
Con Cannot use link-text
You cannot have text link to a URL. When you link to a website you have to post the full URL instead. Instead of having the name of the website or article like, Slant, you instead have to post http://slant.co
. It's especially annoying if you have a long URL that takes up a lot of space in the document.
Con No support for Right-To-Left languages
Mixed text is scrambled, and text-alignment is wrong.
Con Doesn't work on all mobile phones
Not compatible with Android OS version 4.1 and 4.2.
Con Infrequent updates and new features
WorkFlowy works well but it is hardly ever updated, in comparison to Dynalist, which works in a very similar way but has more features and is updated weekly.
Con Only supports one big text file
Although with Workflowy's focus feature this can work, you might prefer managing separate text files.
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
