uSkyBlock

Table of Contents

This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.

uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.

Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock

uSkyBlock gives you a complete Skyblock foundation with island progression, deep customization, and a maintained open-source codebase you can build on long term.

Complete Skyblock gameplay. Build your server around islands, progression, challenges, and party play.

Deep customization. Shape the experience with focused configuration including challenge design, biome options, custom islands, and more.

Integrates with your server. Extend uSkyBlock through its public API and placeholder support so it fits cleanly into your server.

Open source with proven lineage. uSkyBlock is fully open source under GPLv3, free to run, and backed by more than a decade of project history.

Maintained for modern servers. Continues to evolve for current Paper and Spigot versions, with new features, docs, support, and maintenance.

International by default. Support international player communities with bundled translations into 53 languages.

Amazing to hear from you! Yes - it's been consistently maintained by different people throughout the years - sometimes more or less actively. We've been running it non-stop on our server since 2012 :)

Great to hear there is still a "following", I still think it was one of the better mods for Minecraft at that time.

It was fun being involved with this project and I would not mind to play it again to see what has been improved and/or added.

It is also nice to see that the picture has not been changed on the page, Razorax is the ginger one, Talabrek (the original owner and creator)is the one hanging on and I'm in the black suit, (I still have the same suit when I open Minecraft).
Let me know the server and I might pop in one day

Hi,

I have a problem with the /c that doesn’t work. When I run the command the server returns me: An internal error occured while trying to Perform this command !

How can I fix that ?

Hey,

i currently got a new chat plugin that finally allows me to use chat variables,

i think i remember that i once saw a variable for island levels, so the players have the number of their island levels in the chat.

Are this variables still working ? Or have they been removed, i can't find them in the documentary.

Thank you, HALOween.
