Thumbor is an easy-to-use thumbnail generator with crop and resize features. It uses OpenCV to detect visages and crop smartly. It's open source and well maintained.

Can be deployed on Docker. It's simple to install and use and work as a web service through URL exchange. You give to thumbor your image URL, it gives you back the work done (resize, crop mainly).
Ideal candidate use
Any site needing avatars or photo like Azhàr deployment or Auth Grove for profile pictures.
Zed could also use it for the artwork thumbnails.
MediaWiki SaaS
The MediaWiki SaaS can directly use Thumbor by sending queries intended for thumb.php to Thumbor instead.
Per T1895 notes:
At Wikimedia:
- they prepared plugins at operations/software/thumbor-plugins for every format supported by Mediawiki.
- MediaWiki is NOT configured to use Thumbor: the requests to thumb.php are instead directed to Thumbor instead to be directed to MediaWiki
