Developer's Toolkit 1.3.1

by JosTheDude on Oct 28, 2025

This updates the modpack to version 1.3.1 on 1.21.10 and includes a few mod additions and removals.

We now include a Modpack ZIP in GitHub releases!

For users not utilizing a Modrinth-compatible modpack manager such as PrismLauncher or the Modrinth app, we now include a modpack zip with all mods and other utilities. This can be extracted to install mods into a pack manually or imported into the CurseForge App.

We've added the lang-keys resource pack in order to facilitate resource pack and/or MiniMessage translation key work. Installing this resource pack disables all languages to see their raw keys in Minecraft.

This update adds Scribble and WorldEdit. The prior is useful for book design and configuration work. WorldEdit is a general utility for build management and schematics.

This update removes NoChatReports as it did not fit modpack scope. You are welcome to install it yourself if needed.

Developer's Toolkit 1.3.0

by JosTheDude on Oct 26, 2025

Download

This release updates Developer's Toolkit to 1.21.10 and ships a BUNCH of utility changes and more!

This modpack release will likely require a full configuration reset; an incredible amount of mods were swapped for variants or removed due to version compatability.

The size of the pack has massively been reduced. We now only include 61 mods in comparison to the 113 of the original 1.2.1 release. This is for both performance reasons as well as to make the pack easier to update going forward.

All major utilities are still bundled or have been consolidated. You are encouraged to install mods for specific use-cases yourself.

We've officially migrated to Simply Optimized as our base pack due to issues during the 1.21.5 release cycle.
