The limits were added on April 21, 2022, to prevent spam. ID verification raises these limits to 200 models, 200 meshes, 200 decals and 10 plugins. By default, each user can publish up to 10 models, 10 meshes, 10 decals and 2 plugins. On the Creator Marketplace, users have a limit on how many items they can publish on the marketplace per 30 days.

In July 2022, the Creator Marketplace was given a new look, it is now separate from the domain, instead, it's on the domain. On April 20, 2022, Roblox announced monthly marketplace submission limits that would be in effect on April 21, 2022. The paid plugins update was implemented later that same month. The announcement also revealed plans for many other marketplace types to become paid access in the future. In December 2019, RoxyBloxyy announced plans for paid plugins. Sometime in late 2018, Roblox removed the ability for users to search for marketplace items that are off-sale, due to many assets by developers being stolen by others with no credit.
