A frontend for modern day YT. Runs on Invidious. Feel free to improve this however you'd like, you can use it for a 2012L YouTube revival given the right PHP knowledge.

• Uses the original 2012L YouTube player.
• Gets video recommendations and fully implements player end-screen + theater mode.
• Gets all needed video information, such as likes and dislikes.
• Gets comments.

Host this on any site, works anywhere. Does not require any DB setup.
Make sure you copy html5_player_template_2012L in the root.
Once you've gotten the key, go to the /static/ folder and edit the config file to use your API key.
If you did it right, it should work. Enjoy.
