As we think about how to best enable developers, we sometimes reevaluate existing features to make sure they are still valuable to developers. Every Roblox feature—even features that have not been updated in years—incurs a maintenance cost. We have to test to make sure each feature continues functioning properly, harden against the latest security vulnerabilities, and upgrade to the latest technology.
With this as our ultimate goal, we will be starting to remove Sets from our product in the coming weeks. Sets were collections that developers could use to organize content which could be shared with others. To find out what we are working on instead, take a look at our Platform Roadmap.
How will this impact me?
Within the next few weeks, you will no longer be able to access Sets from the website or Studio Toolbox. Note that you will still be able to access the endpoints temporarily if you want to export your data.
On December 1st, we will be ending support for Sets entirely. If you are using in-game APIs like InsertService:GetUserSets() and InsertService:GetBaseSets(), we recommend that you move to another data source such as a Lua table before this date, or your scripts may break.
What should I use instead?
Unfortunately we have no direct replacement for Sets. Feel free to make feature requests for similar functionality you would like to see in the future.
