What is Pylon?
Pylon is an upcoming Minecraft Java technology plugin that will hugely expand vanilla gameplay with new content: electricity, diesel machines, new fluid pipes and fluids, logistics, useful tools and weapons, and much, much more!
Pylon is built using Rebar a powerful framework that allows adding custom blocks, items, researches, etc. Rebar also implements complex systems such as fluid handling logic and cargo routing. Pylon is actually a Rebar addon.

Rebar & addons
Pylon is built using Rebar, a plugin we developed alongside Pylon to allow developers to easily create new blocks. With some programming knowledge, you can easily create and release your own addon for Pylon with your own blocks, items, researches, recipes, etc.
Addon development
Currently, addon development is not supported due to how rapidly Pylon and Rebar are still changing.
See the following code to get a feel for how Rebar works:
Q&A
| Question | Answer |
|---|---|
| How do I install Pylon? | Read the installation guide at https://pylonmc.github.io/home/installing-pylon/. Beware that Pylon and Rebar are still experimental and you should not run them outside of an expendable test server. |
| Will Rebar support Slimefun addons? | No. Migrating from Slimefun to Rebar 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. |
| What versions will Rebar/Pylon support? | We plan to keep each Pylon and Rebar 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/Rebar will only support one version of Minecraft. This means you will need to use older versions of Pylon/Rebar for older versions of Minecraft. Critical fixes will be backported. |
| What server software can Pylon/Rebar run on? | Paper or paper forks only. Folia support may come later down the line. |
| Will Pylon/Rebar support bedrock (via Geyser)? | 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. |
| When will Pylon be ready? | See the 'Provisional Timeline' section above |
| How can I submit a translation? | We do not currently accept translations due to how quickly the plugin is changing (any translation would go out of date quickly). There will be an announcement when we are ready for translations. |
If you have a different question, drop a message on Discord and we'll be happy to answer.
Why Pylon?
Addons
Already 9+ addons being developed with many more planned
We anticipate a rich addon ecosystem
Create your own addons with a bit of programming knowledge
Customisation
The unlocks and costs of each research are configurable
All recipes are configurable
Most blocks and items have settings determining their tick rate, speed, diesel usage, etc
Performance
Far superior performance to Slimefun as we designed for performance from beginning to end
Even huge multiblocks have almost zero performance impact compared to a normal Pylon block
Most of Pylon/Rebar will eventually run asynchronously
Systems like fluid pipes and cargo were designed from the ground up in the most performant way possible
Pylon/Rebar will have a wide range of performance settings, including tick rates, per-player block limits, and more
Stability
Easily disable any problematic blocks or items
Pylon will refuse to start if it detects any configuration issues
Blocks that throw errors will be safely unloaded
Removing addons is safe, with all the data kept intact and restored if the addon is re-added
Pylon data is stored in the world data itself - desyncs are very rare and there's no need to keep extra backups (cough)
