Mod UI inspiration

We've collected mod UI's designed by popular games, so you can use them for inspiration when creating an interface to browse mods in your game.

Posted by on (updated ago)

Our mission at is to make modding accessible for players, and drive adoption by creating tools for game developers that help you launch and run a successful mod community with as little effort as possible.

  1. Step one in this mission is using our API to make mod installation a beautiful one click process.
  2. Step two and the purpose of this guide is how to present mods to your players.
  3. Let's begin!

Game UI's vary quite a bit, which is quite apparent when you see how differently each game approaches the presentation of mods. Some like Garry's Mod have browsing and searching interfaces built in, while others use web overlays and links only and do all of the work of installing mods silently behind the scenes.

Our UI

We'd like to see more complete and powerful modding UI's created in the future, which is why we are working on an open source easily customised web app - which will show what is capable of, and give developers a foundation to edit and build on top of when creating their own mod UI. The work is still in progress, but as soon as it is complete it will be shared here.

Game UI's

Overall we found the UI's implemented by games to manage a users mod collection to be quite basic. We intend to solve this through the creation of powerful plugins that does the grunt work for the engine you are using. Here are some of the challenges we hope to help you overcome:

  • Engines are not designed to create web-like UIs: No problem use ours instead, or if you can embed Chromium you will be able to use our web app and hook into it's callbacks.
  • Shipping a game to a deadline is hard, building non-core tools is time I don't have: We understand which is why our plugins are designed to be end-to-end solutions. Add your game to the site, request your API key, then find your engines plugin. If your engines plugin is not yet available, you can use our API or SDK to get mods downloading, and use our web app for the UI. Jump on our discord to get help, we can even work with you to create the plugin and release it at the end of the process for other developers to use.

We hope you enjoyed this roundup of mod UI's. It is clear that most UI's allow little interaction in game (if any), if the adoption of modding is to grow we believe it needs to be as beautifully presented as DLC is - and where we hope to get to with our default open source UI's that anyone can use.

If you have created a mod UI for your game - we encourage you to let us know and we will include it in this guide.
