mod.io is an cross platform mod service for game developers created by the team behind ModDB.com and IndieDB.com. It can be integrated in-game using the REST API, C/C++ SDK or engine plugins (if available) Unity is ready and Unreal Engine is in development.

Features include:

  • Platform agnostic (support 1 click mod installs on Steam, Epic Games Store, Discord, GOG, itch.ioand even consoles in the future)
  • Clientless (mod.io has no other dependencies and works behind the scenes in your game)
  • Embeddable web app UI, so you can integrate your mod community anywhere
  • Powerful search, filtering and tagging of mods
  • Moderation and reporting systems built-in

Steps to getting mod.io integrated:

  1. Add your game to our test environment or production
  2. Read our API documentation for an overview of how mod.io works
  3. Choose an Engine Plugin, API or SDK to integrate mod.io into your game and mod making tools
  4. Ready to launch? Add your game to our production environment then let's discuss promoting your release
  5. Need help? Our team is available on Discord to assist and our getting started guide has more information for you

Benefits of using mod.io:
mod.io offers the same core functionality as Steamworks Workshop (1 click mod installs in-game), plus mod hosting, moderation and all of the critical pieces needed. Where we differ is our approach to modding and the flexibility a REST API offers. For example:

  • Our API is not dependent on a client or SDK, allowing you to run mod.io in many places such as your homepage and launchers
  • Designing a good mod browsing UI is hard, our plugins ship with a UI built in to save you a lot of effort and help your mods stand out
  • We don’t apply rules globally, so if you want to enable patronage, sales or other experimental features, reach out to discuss
  • Our platform is built by the super experienced ModDB.com team and is continually improving for your benefit
  • Your community can consume the mod.io API to build modding fan sites or discord bots if they want

Large studios and publishers:
A private white label option is available to license, if you want a fully featured mod-platform that you can control and host in-house. Contact us to discuss.
