Here is a list of tools I’ve made some made by others that I use & would highly recommend.

Jiiris

Jiiris originally it started as a “before & after screenshot” tool to show the visual changes in code merge requests, but now has tools for checking alignment, contrast, accessibility color filters, color picker with support for named colors, basic drawing tools & hotkey’d export as image to clipboard.

It’s free to use, client-side only and feedback would be appreciated!
