Introduction to Piped, an open-source YouTube mirror website. It is ad-free, does not track users, lightweight, supports dark and light themes, supports 4K, supports PWA, does not connect to Google services, and is very friendly to the domestic network environment. I tried it myself and found that there is no content filtering, and it can be directly played on the telecommunications network. For other networks, you can test it yourself. This kind of YouTube mirror website can be recommended to classmates who have poor network conditions and need to use YouTube services.

Invidious is a YouTube mirror website that is open-source and does not require VPN. It supports multiple languages, does not require login, does not track users, has no ads, and does not filter content. It also supports subscriptions and YouTube data import/export. I tried it myself, and although it can be opened, the playback speed depends on your network, as the server of this YouTube mirror is located overseas. You can choose a server with decent speed.

LibreTube is an Android version of an open-source YouTube mirror software. Simply put, it is a third-party client for YouTube. However, this software can be directly connected to the domestic network. The interface is very refreshing, with no login or ads. The video quality is also above 1080p, saving you the membership fee. It is highly recommended for friends with poor domestic network conditions. I searched and found that even though some accounts and content may not be filtered out for domestic network access, it is currently playing smoothly and has a low profile.
