uploads.scratch.mit.edu has been notable for being an alternate server of Scratch, meaning that users can access certain pages on it, send requests to the main Scratch website, and interact with Scratch features. People have used this to their advantage to access parts of Scratch when the main website is down.
Not all pages on Scratch can be viewed on uploads.scratch.mit.edu, and users who try to view them get an error message. The only pages accessible on uploads.scratch.mit.edu are pages that use the old, Scratch 2.0-style header, which are not yet migrated to scratch-www; and pages that have been migrated, but not yet had their old code removed. Pages using the Scratch 3.0-style header that were not migrated from an existing 2.0 page can no longer be accessed on the uploads subdomain. Exceptions include the following pages:
- About Scratch
- Community Guidelines
- For Educators
- For Parents
- Our Team
uploads.scratch.mit.edu has also a different favicon. It is the Scratch 1.0 website's favicon.

- Kenny2scratch. (26/5/2020). "Scratch that (), all of the page differences are because of 3.0 - I imagine that anything that still has the old 2.0 header (thinner, darker blue/purple) will be identical on the uploads site; whereas for anything that was changed, we can see the original 2.0 version on uploads." https://uploads.scratch.mit.edu/discuss/post/4060345/
