Pro Capturing (screen, video, a window, etc.) with annotation + automation
Capturing (screen, video, a window, etc.) with annotation + automation makes for some powerful workflows.
Annotation is key for research on any project size. Capturing screenshots, editing them ("annotating"), converting to a PNG, removing the background to make a transparent version, saving to google drive, creating large+med+sm sizes, uploading thumbnails, is an example of a workflow you could create. The list goes on...
You'll find the same strength & depth in features for image handling also for text, videos, other files by type, and on and on..
Pro Can capture video too
Apart from still images, ShareX allows the user to record unlimited video with all the options available for normal image capture.
Pro Has an editor
It has its own screen editing tool.
Pro Freezes screen when you capture
When you enter a capture mode, the screen content is preserved as it was when you started capturing by default. However there is a special "Light" mode where the screen does not freeze.
Pro It has a dead simple way for creating animated GIFs
It is great for creating software tutorials or highlighting new features in a sales function - nothing beats a well-placed animated GIF in an email.
Con Impossible to add new functions
While keyboard shortcuts can be changed for the available actions, there is no way to add custom actions which in turn limits the functionality of the app.
Con Breaks on macOS High Sierra / Chrome or Firefox
Doesn't support side by side windows.
Con Limited window sizing capabilities
You can use 1/2 of the screen vertically and horizontally (divide into 4 parts). You can also use the screen in thirds too, but only the left and right third: you can't use the 1/3 in the center. There is no way to do a more granular distribution.
Con Not maintained
The software is free, but no longer seems to be maintained.
Con Doesn't work with any Adobe products
There are some apps like Adobe Reader that do not work with Spectacle. Basically, any app with a heavily customized UI that breaks OS X accessibility will not work correctly under Spectacle.
Con Scrolling window capture doesn't work always as expected
Sometimes might need to use another screen capture software to capture a scrolling page.
Con The editor is rather simplistic
Con Too complicated
This is extremely customizable, but extremely complex! If you want something simple and intuitive out of the box, stay away from ShareX.
