-## Comparison with other sticker pickers
-
-- Scalar is the default integration manager in Element, which can't be self-hosted and only supports predefined sticker packs.
-- [Dimension](https://github.com/turt2live/matrix-dimension) is an alternate integration manager. It can be self-hosted, but it's more difficult than Maunium sticker picker.
-- Maunium sticker picker is just a sticker picker rather than a full integration manager. It's much simpler than integration managers, but currently has to be set up manually per-user.
