Yes, and all the download sites and tools don’t use anything else either. They all just wrap yt-dlp.

If it stopped working for you, you might have to read the docs on the specific error you’re getting to see how to get around it. YouTube does try to make it harder, but it’s technologically difficult to fully block. There are workarounds for basically every case as far as I’m aware.

Just using yt-dlp also works, but locally.

If you’re using a keepass database, Keepass2Android can natively sync with many cloud options including self hosted and generic ones, even without specific “companion” apps. That’s what I use. In my case, it’s backed by my NextCloud, but it used to be Google drive before.

Just also sync the file on your PC, merging changes from different clients is part of the keepass database format and “just works”.

Also VaultWarden works great if your can self host it, but I prefer keepass for a variety of features and integrations.

Forgejo was soft forked from Gitea after they went commercial and changed the license (I think). If there aren’t any so far, expect pay walled features eventually.

Forgejo turned into a hard fork after communication issues between the teams. I haven’t looked too deeply into it (as I don’t really care about the fact that it’s a hard fork now). This means while it used to be a drop-in replacement allowing you to go back and forth between the two, it’s now an active conversion, I think.
