ThirdTube is a work-in-progress homebrew YouTube client for the New 3DS. The project is inspired by NewPipe, it accesses the mobile version of YouTube, parses the important part of the downloaded html and plays the stream using the fast decoder taken from Video player for 3DS by Core-2-Extreme. It does not run any javascripts or render html/css, so it’s significantly faster than YouTube on the browser. The name is derived from the fact that it is the third YouTube client on 3DS, following the official YouTube app (discontinued) and the new 3DS browser.

Note from developer:

This application is still in the alpha stage, you may encounter crashes and other bugs. If you find one of those, it would be helpful to open an issue on the GitHub repository.

How to watch Youtube on 3DS with ThirdTube (蓮。村長 / RYuta)


New 3DS (including a New 2DS) with Luma3DS installed and DSP1 run. At least 8.1.0-0 is needed (not tested on minimum system version).

Old 3DS is not supported, as it lacks of hardware-decoding capability and cannot even play 144p at a constant 30 FPS.

Known issues

Extracted stream urls randomly return 403 and the video playback fails The reason is unknown, but a temporary workaround is to press Advanced Tab -> Reload when this happens.

Stream downloading randomly slows down (about 10% of the times) This is due to YouTube (probably deliberately) throttling the download speed. The workaround is the same as the 403 issue; reloading will fix it.

Long comments are cut This is intentionally done for a performance reason and probably fixable by, for example, folding the comments by default.

  • Added support for playlists.
    • Now playlists appear both in search results and suggestions.

  • Fixed showing "Settings" in the hamburger menu when you are already opening settings.
  • Fixed httpcContext resource leaking when redirection occurs, which caused the app to stop working.
  • Fixed broken playback when playing videos with non-standard heights.

Release notes.


  • Core 2 Extreme - For Video player for 3DS which this app is based on. Needless to say, the video playback functionality is essential for this app, and it would not have been possible to develop this software without him spending his time optimizing the code sometimes even with assembly and looking into HW decoding on the new 3DS.
  • dixy52-beep - For in-app textures.
  • PokéTube - For the icon and the banner.
  • The contributors of youtube-dl - As a reference about YouTube webpage parsing. It was especially helpful for the deobfuscation of ciphered signatures.
  • The contributors of pytube - As a reference about YouTube webpage parsing. Thanks to its strict dependency-free policy, making it possible to port some of the code without difficulty.
