Because of the increasing hostility of YouTube, the public availability of the Invidious service was discontinued on 2024-09-27. Registration of new accounts is disabled since 2024-08-22. Access by unauthenticated users is disabled since 2024-08-28. All accounts which did not explicitly opt out were deleted on 2024-09-29.
This information site is scheduled to be deleted in late Q4 2024.
Previously, the following services were also publicly available:
They are no longer offered, as Twitter (which no longer exists in its previous form), Reddit, and YouTube have become extremely hostile to third party applications, which made them unreliable and forced the developers (at least for Libreddit) to discontinue development.
The recommended migration path is to use alternative hosted instances (https://nitter.net has been mostly working at the time of writing this) or discontinue usage of that platform.
