Slimefun is a plugin which aims to turn your Bukkit/Spigot Server into a modpack without ever installing a single mod. It offers everything you could possibly imagine. From Backpacks to Jetpacks! Slimefun lets every player decide on their own how much they want to dive into Magic or Tech.
We got everything from magical wands to nuclear reactors.
We feature a magical altar, an electric power grid and even item transport systems.
This project originally started back in 2013 and has grown ever since.
From one single person working on this plugin back then, we grew to a community of thousands of players and over 100 contributors to this project.
It currently adds over 500 new items and recipes to Minecraft (Read more about the history of this project).
But it also comes with a lot of Addons too!
Check out our Addons, you may find exactly what you were looking for.

Slimefun 4 can be downloaded for free on our builds page.
We currently provide two distinct versions of Slimefun, development builds and "stable" builds.
Here is a full summary of the differences between the two different versions of Slimefun.
| development (latest) | "stable" | |
|---|---|---|
| Minecraft version(s) | 🎮 1.13.X - 1.15.X | 🎮 1.13.X - 1.15.X |
| automatic updates | ✔️ | ✔️ |
| frequent updates | ✔️ | ❌ |
| latest content | ✔️ | ❌ |
| Discord support | ✔️ | ❌ |
| Bug Reports | ✔️ | ❌ |
| testing before release | ❌ | ✔️ |
| change logs | ❌ | 📝 change log |
| Download link | 📦 download latest | 📦 download "stable" |
❗ We wholeheartedly recommend you to use development builds, they are the most recent version of Slimefun and also receive the most frequent updates!
Here's why...
"Stable" builds do not receive frequent updates or fast patches. As time goes on, bugs are fixed but it will take some time until these fixes make it into a "stable" build. We will also not accept or review any bug reports from "stable" builds. They are in fact just old development builds that seemed to run fine without any major issues.
Why use a "stable" build then?
While "stable" builds most definitely contain more bugs than development builds due to their very slow update schedule. you can be sure that they will not include game-breaking issues, but rest assured that development builds almost never contain such issues either. If your server or business however heavily depends on a version of Slimefun that does not change/update a lot, you are forgiven if you choose the "stable" branch. But development builds will bring you the best experience, both in terms of features and bug fixes.
What exactly are these "stable" builds then and why do you put them in quotes?
"Stable" builds are literally just outdated development builds that seemed to run fine without any major issues. But they are far from bug-free hence why actually calling them stable would be hypocritical. However these builds can only really stay "stable" if there are enough people using development builds and report any bugs they come across. Otherwise potential issues may go unnoticed and slip into a "stable" build. Again, we really recommend you to choose the development builds. But since a few people really wanted "stable" builds, they are now an option too.

This is an open-source community project, so your contributions keep this plugin alive!
Pull Requests can be fixes, changes or even additions, but please keep in mind that if you add too much content to Slimefun 4, you should maybe consider making an Addon for it instead (Developer Guide).
Slimefun uses Sonarcloud.io to monitor Code Quality.
| Overall Maintainability | "Code Smells" | "Technical Debt" | Test Coverage |
|---|---|---|---|
Code Smells are portions of the source code that are confusing, lack documentation or are just done very badly in general. These code smells should be held to a bare minimum.
Please contact us on Discord before working on any code smells. Some design patterns may not be changed abruptly because an addon might depend on them.
Technical Debt is basically an estimate for how long it would take to fix all issues and code smells.
Slimefun now also uses Automated Tests to determine whether an update could break something. The coverage shows how much these tests cover. Higher coverage means less breaking changes and as a result also better and more reliable builds.
Due to this being a very huge project though, getting to 100% coverage is probably close to impossible. But increasing that number even slightly still helps. So feel free to write Unit Tests for Slimefun and place them in the /src/test/java/ folder.
Slimefun4 uses various systems that collect usage information or download automatic updates as well as the latest information about the project. We do not collect any personal information from you but there are some services that may gather or download some form of data.
You can opt-out of the Auto-Updater and stats collection at any time.
Automatic updates
Slimefun4 uses an Auto-Updater which connects to https://thebusybiscuit.github.io/builds/ to check for and download updates.
This behaviour is enabled by default but can be turned off under /plugins/Slimefun/config.yml.
We highly recommend you to keep this on at any time though, as you could be missing out on important patches.
Metrics and Statistics
Slimefun4 uses bStats to collect anonymous information about the usage of this plugin.
This is solely for statistical purposes, as we are interested in how Servers/Players use this plugin.
All available data is anonymous and aggregated, at no point can we see individual server or player information.
All of the collected data is publicly accessible: https://bstats.org/plugin/bukkit/Slimefun/4574
You can also disable this behaviour under /plugins/bStats/config.yml.
For more info see bStats' Privacy Policy

This information includes (but is not limited to)
- list of contributors, their username and profile link (from the repositories
TheBusyBiscuit/Slimefun4,Slimefun/Slimefun-WikiandSlimefun/Resourcepack) - amount of open issues in this repository
