Cross Platform Mod API & SDK
A downloadable tool
mod.io is a cross platform mod support SDK created by the team behind IndieDB.com and ModDB.com. Our aim is to make modding easy to support and accessible across every store, platform and device, by building flexible APIs and dashboards studios can use to setup and run a mod community in your game. In addition to the API mod.io features plugins for popular game engines such as Unreal, Unity, and C++ SDK which provide drop-in support with UIs to power mod discovery, installation, marketplace and more.
If you are familiar with Steam Workshop, mod.io should be easy to understand. Key functionality we offer is:
- Fully hosted mod platform
- Moderation and safety tools built in
- Powerful search, filtering, tagging and sorting
- Ability to subscribe, rate and download mods
- Attach metadata, versioning and other data to content
- Support for mature content
- Very customizable web UI and admin dashboards
- Marketplace for premium mods
Where we differ is primarily driven by the open nature of our platform which is not tied to a client + SDK. Key differences include:
- Our platform is clientless, 100% standalone it works behind the scenes
- You can embed mod.io into your game on any store or platform that will support it
- Marketplace, creator rewards, and monetization systems are built in
- White label support so you can embed mod.io into your games homepage, launchers, discord channel and have players authenticate using your account system
- We are a fast moving company aiming to lead UGC innovation and offer a featureset comparable to industry leaders like Roblox and Fortnite to all games
- Via your games dashboard, you have complete control over your UGC community, allowing flexibility to fit any use case
- Notification systems and detailed metrics data to surface key insights and interact with your top creators
- For large studios and publishers we offer an enterprize solution that can be licensed if you require a private solution
