I'm also working on integrating this into a Telegram bot (https://github.com/joshbarrass/ArchiverBot) that will allow me to archive things to my NAS whilst on the go. UArchiver is provided with the URL and will just download the files without me needing to care how.
I've been too busy with other things to put major work into it recently, but both projects are in a functional state, just without tonnes of features or supported sites. Whilst it may not seem like much, I'm particularly pleased with the GitHub Actions pipeline I set up recently, which will automatically upload UArchiver releases to PyPi, and automatically build ArchiverBot Docker images and upload those DockerHub.
