Out of the box it can play audio in the background, and now that extensions are available you can block ads as well. You don’t really need constantly updating 3rd party clients or questionable firewalls anymore if you just want usable youtube on a phone.
As far as I know, you can’t log in to your account with newpipe. I use revanced and have no issues
You will have to add your channels once. These can be backed up into a file and imported onto another device. Not super convenient but compared to how annoying the official app is I am OK with it.
It won’t track watch status across different platforms/devices though. Revanced is significantly easier to setup and use.
Significantly easier? Newpipe is simply installed from fdroid. I’ve only looked for a few minutes but it looks like revanced “patches” YouTube. Does that mean it doesn’t create its own app but overtakes another? How does that interact when the app underneath gets a play store update?
I’ve been using it for years; just download and install the apk from the website like any other side-loaded app. Yes it modifies the original youtube app, replacing it. I’ve never had an issue with the main app updating and breaking anything. Updates to revanced have to be applied manually the same way as the original install, but I’ve been super lazy and gone several years at a time without updating at all and I’ve never had an issue.
I used to run the original vanced app the same way; rarely if ever updating. It just hasn’t been necessary. Hell, the only reason I’m not still using original vanced app is because the device it was installed on has a broken screen.
Revanced is essentially the same app as the original youtube app with all premium functionality; but with adblock, sponsor block, and a huge host of toggles to show/hide almost every part of the UI or modify the apps behaviour (things like fixed quality settings instead of just ‘auto’ or a default playback speed).
