# ServerPackCreator turns a modpack update into a server pack

> Griefed/ServerPackCreator is a Kotlin tool that builds a Minecraft server pack from a Forge, NeoForge, Fabric, LegacyFabric or Quilt modpack. It removes the repetitive file assembly behind every release, and it leaves the testing obligation with you.

## The modpack update treadmill that started this project

ServerPackCreator exists because of one recurring chore. When a modpack author ships a new version, a matching server pack has to be assembled again, and doing that by hand is tedious enough to push people toward scripting. The repository description states the goal plainly: "Create a server pack from a Minecraft Forge, NeoForge, Fabric, LegacyFabric or Quilt modpack!" The author ties the project to a specific case, updating the modpack Survive Create Prosper 4 and getting tired of rebuilding a server pack for every test and every release. That history matters for expectations, because the tool is framed as an automation of a known manual task rather than a managed hosting platform. The audience is narrow: modpack authors who publish server distributions, and the server admins who consume them.

## Five loader families handled as separate targets

Coverage is the clearest strength here and the clearest scope limit. Forge, NeoForge, Fabric, LegacyFabric and Quilt are all named in the project description, and the repository topics back that up with entries such as forge-server, fabric-server, neoforge-server and quilt-server. Each of those names refers to a server side variant of a loader, which points at ServerPackCreator working loader family by loader family rather than converting a pack from one loader into another. The README excerpt does not spell out the transformation steps, so the exact handling of client only files is not documented there. What the description does state is the direction of travel. A modpack goes in, a server pack comes out, and the surrounding sentence says that running the tool during a modpack update gives you a server pack for that new version.

## A Gradle multi-module project built around a plugin model

The source layout carries more information than the README does. build.gradle.kts, settings.gradle.kts, buildSrc/, gradle/, gradlew and gradlew.bat describe a Gradle Kotlin DSL build, and Kotlin is the primary language of the project. Alongside the Gradle scaffolding sit several serverpackcreator-prefixed modules: serverpackcreator-app, serverpackcreator-api, serverpackcreator-clientside, serverpackcreator-grinder, serverpackcreator-help, serverpackcreator-homepage and serverpackcreator-web-frontend. Four further directories are named as plugins: serverpackcreator-plugin-example, serverpackcreator-plugin-grinder, serverpackcreator-plugin-selfextract and serverpackcreator-plugin-servertest. The names point at a core application plus an extension interface, where grinding, self extraction and server testing are pluggable steps rather than hardcoded ones. There is also a docker/ directory and a spc.install4j file, which suggests a packaged installer path alongside the container route. The excerpt does not define each module's contract.

## Getting the tool and running a first generation

The README excerpt contains no command to copy, so the honest tutorial is a path rather than a shell recipe. Builds are published as GitHub releases, and the release list shows three recent entries: 9.3.0 on 2026-10-17, 9.3.1 on 2026-10-18, and a continuous channel build on 2026-10-19. The continuous tag carries the newest code and also the least stability behind it, for reasons covered below. A Docker image is published under the maintainer's DockerHub account, and the project homepage at serverpackcreator.de is the central entry point, with a blog and a Discord server linked from the README. For a first real use, the sensible order is to pull a release or image, point it at a modpack for the loader you actually ship, read the generated output before deploying it anywhere, and then follow the README instruction to test the result. The README is emphatic about that final step and repeats the demand to test server packs before shipping them.

## Pre-release builds break, and the author says so

The risk section is unusually direct, and it is the part of the documentation that should shape an adoption decision. The README warns that things will break with alpha releases and that stuff may break with beta releases, and it advises backing up your ServerPackCreator directory in your home directory before running an alpha, beta or in-dev build. It goes further. If you distribute server packs generated with a pre-release, you do so at your own risk, and the author declines responsibility for errors in a server pack caused by using one. Beside that sits the broader disclaimer that ServerPackCreator is not a guarantee for working server packs, that you are still expected to be knowledgeable about your modpack, server packs in general, server administration and managing your Java installations, and that the tool is not intended to take all the work off your shoulders. This is a generator with a testing obligation attached.

## LGPL-2.1, the licenses directory, and the gaps in the docs

The license identifier for the project is LGPL-2.1, and the repository root carries both a LICENSE file and a licenses/ directory, so per-dependency license texts appear to be tracked next to the project license. The README excerpt does not discuss the licensing of the server packs that ServerPackCreator produces, and it does not explain how mod licensing carries into a distributed pack, so anyone shipping generated packs to players needs to resolve that separately. On maintenance, the repository is not archived and the last push was on 2026-10-20, one day after the 9.3.1 release, while the continuous channel build is dated 2026-10-19. The author describes the work as a passion project carried out in spare time and asks for patience with issues and support, which is the kind of signal worth weighing when you plan around issue turnaround.

## Where the manual route and the home-grown script still win

The alternative deserves to be stated plainly, because the project's own origin story describes it: manually creating a server pack for every modpack version, which the author found tedious enough to automate. The manual route means copying the pack, deciding which files belong on a server, and assembling the launcher and install script by hand for each release. That process is slow, but it stays entirely under your control and gets documented in your own notes. A middle path is a script written for one modpack, which handles that pack well and needs rewriting whenever the loader changes. ServerPackCreator's difference is breadth. It aims at the loader matrix as a whole, taking a modpack and emitting a server pack with loader specific handling built in. That breadth is also its cost, since a tool covering five loader families and an extension model carries more internal machinery than the manual path, which is a plausible reason the README hands the final verification back to the operator.

## Conclusion

ServerPackCreator suits modpack authors who release versions often and have already accepted that a generated server pack still needs testing before it reaches players. It does not suit operators who want a managed or verified deployment. Before adopting it, check the release channel you intend to ship from, the loader families your packs actually target, and whether your workflow can absorb the manual test step the README insists on.

## FAQ

### Which Minecraft mod loaders does ServerPackCreator support?

The project description names Forge, NeoForge, Fabric, LegacyFabric and Quilt. It creates a server pack from a modpack built for any of those loaders.

### Does ServerPackCreator guarantee that the server pack it generates works?

No. The README states that ServerPackCreator is not a guarantee for working server packs and that you must test them before you ship them.

### How do I get ServerPackCreator, and how often does it change?

Builds are published on the GitHub releases page, alongside a continuous channel tag, and a Docker image is published on DockerHub. The recent tagged releases were 9.3.0 on 2026-10-17 and 9.3.1 on 2026-10-18, and the last push was on 2026-10-20.

### Do I need to know Java and server administration to use ServerPackCreator?

The README says you are still expected to be knowledgeable about your modpack, server packs in general, server administration and managing your Java installations, and that the tool is not intended to take all the work off your shoulders.
