What can this service do for you?

You have played the game your way, and now you want it your way: an item that does not exist, a mechanic tweaked to your taste, a small quality-of-life change that would make your world perfect. Mod-friendly games like Minecraft invite exactly this, and commissioning a mod is how players have shaped them for over a decade.

This service builds custom mods for single-player use in mod-friendly games: new items, blocks, and recipes for Minecraft (Java Edition), tweaks and additions for titles like Stardew Valley, RimWorld, and Cities: Skylines, and quality-of-life changes to how the game plays. You describe the idea, we confirm what the mod will and will not do, and you receive a working mod with install instructions.

Mods are built for games where modding is permitted by the developer and intended for your own single-player worlds. We do not build cheats, exploits, or anything that breaks the rules of multiplayer games. You receive the source code, so your mod survives game updates with a recompile instead of a rewrite.

Frequently asked questions

Games that officially welcome modding and provide the tools for it: Minecraft Java Edition, Stardew Valley, RimWorld, Cities: Skylines, and similar titles. If you are unsure whether your game qualifies, send the name in your order description and we confirm before starting.

Only where the developer explicitly allows client mods on their servers. We do not build cheats, aim assistance, or anything that breaks a multiplayer game's rules, and we will decline those requests.

Plain words work best: what the item should be called, what it should do, how you want to craft or obtain it. Sketches or reference screenshots from other games help a lot and are welcome with your order.

Game updates sometimes change the internals mods rely on. Because you receive the source code, an update is usually a small fix rather than a new project, and fixes for game updates within 30 days of delivery are included free.

Yes, always, along with build instructions. The mod is yours to keep, and any mod developer can extend it later because the standard modding frameworks are used.

That is up to you and the game's mod distribution rules. Minecraft mods, for example, are commonly shared on public mod platforms. Since you own the source, publishing is your choice.
