Snapshot of the upppy website, as taken in 2023 by the Internet Archive
up.ppy.sh, often referred to as upppy, was a file uploading service run and hosted by peppy. It was first established in January 2007, predating osu! itself1, and was mainly used to share images and files within the osu! community.
Service
upppy was created as a free, lightweight alternative to proprietary image hosting services such as Rapidshare or ImageShack.2
The service did not require any registration to use and allowed anyone to upload files anonymously within its Terms of Service. Similar to certain imageboard sites, upon uploading a file, users were given a choice as to whether to post the upload in the default, catch-all working channel (#random) or in one of the more specific channels:
#anime#game#highres#music#photography#screenshots#torrents#tv#video#wallpaper
Once a file was posted, it became a permanent part of the platform and could not be deleted or edited by the uploader. Much like on Reddit, these posts could still receive comments and be upvoted/downvoted by other users.
Decommissioning
As upppy used Adobe Flash Player in its upload form, new file uploads were effectively frozen starting from December 31, 2020 due to the shutdown of Adobe Flash Player, save for users who were still running very old browsers. Sometime in early 2025, the entire website was taken down completely, leaving only an error page when accessed.
