Creating an App That Sets Up a Minecraft Server by Just Choosing a Modpack

The author, who is not a developer, reports that they entrusted all coding to Claude Code to create a Minecraft server management app for use with friends.

How it works

  1. The author described the desired features in everyday language and pasted in error messages exactly as their friends encountered them. For example, they found and fixed a Windows error caused by a ':' in the file name this way.
  2. Before release, Claude Code reportedly tested the app by automatically clicking through screens with Playwright and a fake server, and checked installation file updates and deletions using Wine.
  3. They regularly assigned code reviews to sub-agents and set up GitHub Actions so that adding only a changelog would result in a signed installer being distributed.

Results

The resulting app handles everything from searching for modpacks, downloading mods, installing loaders, selecting the Java version, to removing client-only mods. If the server stops, it explains the cause in simple terms and reportedly tries to fix it in one go.

Notes

The author did not disclose the number of users or downloads. Code quality was only checked through the author's own testing and friends' usage experience.

Example prompt · Claude Code

Create a Windows app that automatically sets up a Minecraft server for you and your friends by just choosing a modpack.

Input: Supported mod loaders [Forge/Fabric/NeoForge, etc.], modpack source [search site or .zip/.mrpack file], number of servers to run at once [quantity], your PC specs [memory]. First, check the terms of use and public API of the modpack site, and notify if any part does not allow automatic downloads.

When you receive a modpack, create the server folder in this order: download mods, install the loader, select the appropriate Java version, and remove client-only mods. Show server start/stop, console, memory usage, and the address for friends to connect on one screen. If the server stops, explain the cause in simple terms from the log, show what will be changed before fixing, and get confirmation. Only modify the original server folder after backing it up.

If an error message is pasted in, find and fix the cause, and if the same error occurs, show step-by-step guidance to the user. Also, create a screen test that automatically clicks through making, starting, stopping, and fixing with a fake server.

Deliverables: installer, user guide, test list. First, create a server with a small modpack and confirm that one friend can actually connect, then expand to other modpacks.
