Cosmo is a self-hostable universal cape & cosmetic system which works on all major clients* and operating systems.

Cosmo Cosmetics work on all clients, such as Lunar, Badlion, Forge and Optifine. You can offer players cosmetics on every single client* to enhance your Minecraft character.
(* See atmtx.co/compatibility for a full compatibility chart)
All-in-One Discord Bot
Cosmo includes a self-hostable Discord Bot that is used by players and admins to manage their cosmetics. You can import & equip cosmetics, view the shop and purchase items, and even set up creator codes for players!
How do I add cloaks/cosmetics to the bot?
Although some cosmetics are included with Cosmo, you must find your own free cosmetics online or design your own to import into the bot. This can be done with Blockbench.
Can I add features to the bot?
Although editing the Discord Bot files is not allowed, customers can buy the API add-on to unlock unlimited possibilities and develop additional tools for the software. Your users can also use their personal API key to automate actions on their account (you can restrict this to specific roles with Discord’s command system if you'd like).

Terms of Service
By using Cosmo, you are deemed to have given your automatic agreement to the associated terms and conditions, regardless of whether or not you have read them. These terms are subject to change without notice, and you are responsible for keeping updated with any changes. Breaking these Terms will result in your Cosmo instance being blacklisted.
- Redistribution of Cosmo as your own is strictly prohibited.
- Modifying the Cosmo source code is not allowed and will trigger the tamper system. You are only permitted to edit the settings.yml and command.yml files. We have included as much customization as possible in the settings, so you shouldn't need to edit the source code.
- You should not edit user or cosmetic data through files as it may be replicated in other places; when using the Discord Bot or API, it ensures all items are replaced.
- By purchasing Cosmo, you acquire a copy of the resource; modifying or adding additional content does not make you the owner.
- Using Cosmo to create a new product to resell is not allowed.
