Post news RSS mod.io launches mod SDK for Unreal Engine 4

Support user-generated content in Unreal Engine 4 using a plugin from the same creators of IndieDB.

Posted by on

Hello indie developers. 1 year ago we let our community know that the team behind IndieDB and ModDB are building mod.io, a cross-platform mod API for games. Since then 17 games have used mod.io to power over 4,600,000 mod installs for 700,000 players.


Today, we are happy to announce the launch of our Mod Browser and Manager for Unreal Engine 4, which makes it easy to support user generated content in your Unreal Engine 4 games. The plugin is highly adaptable, open-source, has powerful search, discovery and filtering support built in. It is platform and store agnostic allowing you to support modding in more places.

Features include:

  • Platform agnostic, supporting 1 click mod installs on Steam, Epic Games, Discord, GOG, itch.io with plans for full-console support.
  • Standalone, our API is not dependent on a client or SDK, allowing embedding everywhere: in-game, launcher, homepage, discord bot.
  • User Management, allowing for synchronized subscriptions, mod rating, and content submission.
  • C++ and Blueprint, interface built in the Unreal Engine for connecting to the mod.io API.
  • Example Project, is available to help Unreal Engine developers get started.

To celebrate the launch, Victor from Epic Games invited us onto the Unreal Engine live stream, to discuss the plugin, how it works and what our objectives are. The VOD from the livestream and deck we presented are now available below.

MORDHAU a medieval combat simulation, and Playcraft a code-free multiplayer sandbox game builder (releasing this month) are the first two games to launch with mod support powered by the mod.io Unreal Engine plugin.

If you are interested in experimenting with mod support, we'd like to hear from you and invite you to download and start using our Unreal Engine 4 plugin. We look forward to enabling the creativity of your community, and extending the life and success of your game with mods.


This is really cool :D
