The short answer
PostSpark is the daily one: a screenshot editor with backgrounds, annotations, effects and browser frames, free to start. Shotbase is the Mac workspace when capture, edit and share should be one place. Screenshot Studio is the App Store answer, localised and uploaded from a Mac. javiitools covers the tiny pixel accurate cases, Supaste keeps the history, and Mokkit puts the shot on a device.
A raw screenshot says the feature shipped. A framed one says somebody cared. The difference is two minutes with the right tool, and the board has six of them, each for a different two minutes.
Which one for a changelog entry?
PostSpark. Drop the screenshot, pick a background, add a browser frame, annotate the new button, export. It is the editor with the most range on this list and the free tier covers a changelog a week. The rule is one annotation per picture, because a screenshot with four arrows is a diagram.
Which one lives on the Mac?
Shotbase, when capture, recording, editing and sharing should be one workspace. It replaces the folder of untitled PNGs on the desktop with a place that remembers. Supaste is the lighter Mac answer: local first clipboard and screenshot history, bought once, for the day you need the shot from Tuesday.
Which one for the App Store?
Screenshot Studio. App Store screenshots, localised and uploaded from a Mac app, which means the twelve sizes and the eight languages stop being a spreadsheet. The gallery of what good ones look like is in App Store screenshots: inspiration and tools.
Which one for a chat mockup or a tag?
javiitools. Tiny pixel accurate generators for chat mockups, stamps, tags and overlays, free. The chat mockup is the one to bookmark, because a fake conversation drawn by hand looks fake.
Which one puts it on a device?
Mokkit, in seconds, with a transparent background. The device is what makes a screenshot read as a product instead of a window. For the full comparison of device renderers read Rotato vs Protato vs Hano.
The hub is design tools on the board.

Questions
What size should a changelog screenshot be?
1600 pixels wide, exported as WebP under 200 KB, with a 16:10 frame so it reads the same in an email and on the page. PostSpark exports at that size with the frame included, and the padding around the window is what keeps it from looking cramped in a narrow email column.
Is PostSpark free?
The free tier covers backgrounds, frames and annotations, which is a changelog a week. The paid tier adds the larger export sizes, more effects and the presets that save the two minutes on the tenth screenshot. For a solo maker the free tier lasts a long time.
Which tool keeps a history of screenshots?
Supaste on the Mac keeps a local first clipboard and screenshot history, bought once. Shotbase keeps the history inside its workspace along with the recordings. Both mean the shot from last Tuesday is a search away rather than a desktop folder away.
