Quick answer

Which Developer Toolkit release should I use?

Updated 6 months ago
Latest stable file Developer's Toolkit 1.4.0
Game version 1.21.11
Loader Fabric 0.18.4

Developer's Toolkit 1.4.0 is a complete pack release for 1.21.11 with Fabric 0.18.4. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 58 mods in this pack file.

Pack setup

How should I set up Developer Toolkit for players and a server?

Use Developer's Toolkit 1.4.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Developer's Toolkit 1.4.0
Dedicated server setup Match Developer's Toolkit 1.4.0
Pack loader Fabric 0.18.4

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 58
Client only 37
Server only 1
Not labelled 20

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Developer Toolkit?

Developer's Toolkit 1.4.0. Change the pack release and its contents or setup may change too.

58 mods in this pack file

The selected pack release is Developer's Toolkit 1.4.0. That file is for Minecraft 1.21.11 with Fabric 0.18.4. It contains 58 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

About this project

What kind of pack is Developer Toolkit?

Developer's Toolkit

A developer focused modpack with a collection of useful utilities and game optimizations.


This modpack is primarily built for developers, admins, and configurators in mind. It contains a large variety of server utilities that are combined to become a cause of the following reactions:

  • "Oh, was that not just vanilla? My modpack does that for me!"
  • "This is so annoyi- oh wait my modpack has a tool for that!"
  • "I literally cannot live without this"
  • Among other experiences, depending on use-case and usage.

Built to work out of the box with most settings pre-configured. Feel free to modify as needed. See the mod list for full list of functionality, alongside feature list below.
