Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Losslessly Optimising Images
Disclaimer: There may be newer tools with better support for Linux or Windows, but for macOS users, the venerable "ImageOptim-CLI" project ^1 remains a powerful option.
It wraps ImageOptim, ImageAlpha, and JPEGmini in a single executable, and is able to produce visually-indistinguishable image assets with 60-80% reduction in bytecount, for nearly any corpus of unoptimized files. I've used it to great effect as a webperf consultant. Enjoy! :)

screen capture/snapshot utility with image optimization support/configurability
I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg.

Exported png image with color-to-alpha edit is huge
If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng

Losslessly Optimising Images
I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng).
Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).
pngquant --quality=99 --ext=.png --force file.png

Adobe plans to make Photoshop on the web free to everyone
Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image.

Help processing massive videos (16k resolution)
Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development.

(Urgent) Best Image Compressor Sites That Barely Compress?
Not sure what extensions of images you use, but if they’re PNG you could use oxipng: https://github.com/shssoichiro/oxipng
