Pylon is an **upcoming** Minecraft Java plugin that will hugely expand vanilla gameplay with new content, including electric machines, huge multiblocks, a fully-fledged fluid system, a complex smelting system, extensive automation options and much, a research system, and much more. It is intended to supersede Slimefun.

Pylon uses an addon system, meaning anyone can add content to Pylon by writing an addon for it! It also comes with a number of really useful features, such as:

We have built Pylon with performance and stability in mind from day 1:
- Pylon makes **extensive** use of caching and will run most performance-intensive systems asynchronously, as well as makeing use of modern concurrency/performance features such as coroutines.
29
-
- In addition, the plugin will have a broad range of config options to help performance - including per-machine tick rates, the ability to limit the number of machines placed by player/chunk/etc, the tick rate of fluid/energy/etc, and more.
30
-
- The way Pylon is designed minimises the chance of data corruption and has a range of error-handling mechanisms if something does go wrong.
31
-
Note: Pylon will likely not be fully compatible with bedrock.

### Performance
55
+
56
+
-:gear: Even huge multiblocks will have **almost zero** performance impact compared to a normal Pylon block
57
+
-:gear: Most of Pylon will eventually run asynchronously
58
+
-:gear: Performance is literally built into Pylon's design - systems like fluid pipes and cargo were designed from the ground up in the most performant way possible
59
+
-:gear: You will be able to limit the number of each type of block per player or per chunk
60
+
-:gear: Pylon will have many more performance options, such as making fluid pipes tick less often, or reducing tick rates of individual types of machines
61
+
-:gear: We plan to add a purpose-built profiler so you can see exactly what blocks & items are using the most CPU or memory
**Novemeber/December 2025** - Open alpha testing (likely hosted on MetaMechanists - my own server) begins. We will most likely run several seasons of Pylon that each last a few weeks, to iron out bugs, test performance, improve stability and UX, and make sure the plugin is ready to be released.
65
+
-:gear: Easily disable any problematic blocks or items
66
+
-:gear: Pylon will refuse to start if it detects any configuration issues
67
+
-:gear: Blocks that throw errors will be safely unloaded
68
+
-:gear: Removing addons is safe, with all the data kept intact and restored if the addon is re-added
69
+
-:gear: Pylon data is stored **in the world data itself** - no need to keep extra backups
38

**Early/mid 2026** - Pylon is officially released

We've gone to great lengths to make Pylon easy, intuitive, flexible, and most importantly, fun to develop addons for. A lot of painful lessons learnt from hundreds of hours of Slimefun addon development have guided Pylon's API, and the result is something that's intuitive and easy to work with, while being very flexible. Pylon also fully supports addons written in Kotlin, which is much nicer to write than Java.

Currently, addon development is not supported due to how rapidly Pylon is still changing, and the lack of high-level documentation on how to do it. We plan to soon have a detailed guide on how to create an addon and how to take advantages of all the systems Pylon has to offer, so watch this space!

Currently, the core team developing Pylon is:
103
+
### Lead developers
104
+
105
+
@seggan :flag_us: - a veteran Slimefun addon developer (SlimefunWarfare, SFCalc, Galactifun), with a impressive contribution record for SF addons, Paper, and Slimefun. Seggan is responsible for many core Pylon systems, including translation, WAILA, researches, the smeltery, the recipe system, and more.
106
+
@ohmvir :flag_ca: - new to plugin development, but has done a fantastic job getting up to speed and adding lots of base content, like talismans and the beheading sword, as well as a *lot* of various smaller technical changes & bug fixes.
107
+
@overlordidra (me!) :flag_gb: - owner of a Slimefun server for 5 years & Quaptics developer. I have developed many of the core systems including the Pylon guide, fluid system, hydraulics, cargo, diesel, automated tests, block storage, and more.

@ohmvir :flag_ca: - a relatively fresh but enthusiastic face from MetaMechanists who's new to plugin development, but has done a fantastic job getting up to speed and adding lots of base content, like the health talismans and beheading sword, as well as tackling various tasks that need doing here and there.
109
+
### Artists
110
+
@pandicka :flag_cz: - a talented texture pack artist who worked on Slimefun texture packs, and has created the majority of the Pylon resource pack.
60
111
61
-
@overlordidra :flag_gb: - owner of MetaMechanists (a popular Slimefun server) for over 4 years and the developer behind Quaptics. Many of the core systems - most notably the Pylon guide, the fluid system, hydraulics, the automated test code, and the core systems that keep track of custom blocks/entities/items, are his doing.
112
+
### Developers
113
+
@vaan1310 :flag_it: - previously headed a geopolitics server and has been doing a lot of valuable work on the 'smaller stuff' - resolving issues, fixing bugs, adding polishing, making technical changes, and lots more.
114
+
@justahuman_xd :flag_us: - head developer on my server for 3 years and works professionally in the Minecraft space. He has done the majority of the texture pack support side of Pylon, and other various smaller refinements.
115
+
@tinalness :flag_cn: - former Slimefun addon developer (JustEnoughGuide, SlimefunTimeIt, MSUA, AdvancedBan, and more) who has contributed to Pylon (primarily the recipe ingredient calculation system) and also has already written two addons.
116
+
@ihateblueb :flag_us: - has run a Slimefun server (Orchid) for several years and has added some neat content like the elevator.
62
117
63
-
@seggan :flag_us: - a veteran Slimefun addon developer behind SlimefunWarfare, SFCalc, and the very successful Galactifun addon, with a very impressive contribution record for other addons, the Paper server software, and Slimefun itself. Seggan is responsible for many of the core Pylon systems, including most notably the entire translation system, WAILA, the research system, the internal registry system, and the recipe system (and has done lots more smaller features!).

67
-
@ihateblueb who has run a Slimefun server (Orchid) and is helping us add more content (the elevator is her doing!).
122
+
Q: **How do I install Pylon?**
123
+
Read the installation guide at [https://pylonmc.github.io/installation/installing-pylon/](https://pylonmc.github.io/installation/installing-pylon/). Beware that **Pylon is still experimental and you should not run it outside of an expendable test server.**
68
124
69
-
@justahuman_xd who is responsible for many of the more hacky things we do, namely the block and armor texture systems. He also has a *lot* of Slimefun development experience under his belt and has given a lot of useful input and guidance on the project.
125
+
Q: **Will Pylon support Slimefun addons?**
126
+
No. Migrating from Slimefun to Pylon is non-trivial, and we advise addon developers to rewrite their addons entirely to better suit Pylon's progression and style rather than attempting to migrate them 1-to-1.

@.ph.enix who used to manage all our CI - he set up automatic testing on our pull requests, and set up the system to publish new versions of Pylon. Unfortunately, he has left the project, but we are very grateful for all his help!
128
+
Q: **What versions will Pylon support?**
129
+
We plan to keep each Pylon version compatible with the latest version of Minecraft at the time. To make it easier and faster for us to update, **each version of Pylon will only support one version of Minecraft.** This means you will need to use older versions of Pylon for older versions of Minecraft. Critical fixes will be backported.
72
130
73
-
@vaan1310 who has implemented quite a few bits here and there, such as bug fixes and data-driven researches, as well as helping out with pull request reviews.
131
+
Q: **What server software can Pylon run on?**
132
+
Paper or paper forks only. Folia support may come later down the line.

If you're interested in helping out, drop us a message on our Discord server! You don't have to be an expert to help, a little plugin development experience is enough - there are plenty of tasks to do, ranging from trivial to exceptionally complex, so just let us know if you're interested and we can find something for you to do.
134
+
Q: **Will Pylon support bedrock (via Geyser)?**
135
+
Eventually, yes, but it is not a high priority and will be one of the last things added. Geyser is very hard for a project like this to support and there will be some jank.
