Caveat: This is a Flatpak and not all Linux distros ship with Flatpak. But I'll give it a whirl in my Fedora virtual machine. I've seen many flavors of this type of tool floating about, most of them leveraging Tesseract[0], and I've tried a few of them. It fails badly on grainy / noisy images or where the text is warped or skewed in some way. It will not solve CAPTCHAs for you!
...it's a pile of Vala code. What you probably mean is that the author did not make a package for your distribution, and there is no one else who had the time and inspiration to package it. You can be the maintainer you seek.
