A script that can be executed to unsubscribe all the YouTube channels at once.

unsubscribe-youtube-channels.js

var i = 0;
var count = document.querySelectorAll(
  "ytd-channel-renderer:not(.ytd-item-section-renderer)"
);
myTimer();
function myTimer() {
  if (count == 0) return;
  el = document.querySelector(".ytd-subscribe-button-renderer");
  el.click();
  setTimeout(function () {
    var unSubBtn = document.getElementById("confirm-button").click();
    i++;
    count--;
    console.log("channel " + i + " unsubscribed");
    setTimeout(function () {
      el = document.querySelector("ytd-channel-renderer");
      el.parentNode.removeChild(el);
      myTimer();
    }, 250);
  }, 250);
}

Great bro, ty

the button id I think may be something that varies by region, for me it was subscribe-button

Thanks for the script.

Thanks for the script.

Glad, it worked for you.

Oh, I didn't know that. I think YouTube (just like other apps) localizes their web apps in accordance to different countries. Thank you for letting me know.

Great bro, ty

Glad, it was useful.

This one is working. First, you have to go to the bottom of the page and then open up the console.

This ran through everything said i was unsubscribed took about 20 min for 600 subs. Said it was successful but back in YouTube they are all still showing as subscribed. I have tried logging out and in and clear cache but all still showing not 1 removed????
