Is the generated plugin free to use commercially?

Yes. You own 100% of the code generated for you. There are no licensing restrictions on what you do with the output — use it on your own server, sell it, or open-source it.

How it works

From plain English to a compiled
Paper JAR in under a minute

StackNest knows the Paper API inside out — Adventure components, PDC, async chunk loading, Folia schedulers.

Describe your Paper plugin

Write what you want in plain English. Mention commands, permissions, events, GUIs, data storage, Vault, PlaceholderAPI, or any other dependency. The more detail, the better the output.

AI writes full Paper API source

A specialised model generates all Java files, plugin.yml, and pom.xml targeting Paper 1.21.4 by default. It uses Adventure components, PDC for persistent data, and the correct modern event API.

Compiles against Paper 1.21 API

The code is compiled server-side with the Paper API on the classpath. If there are errors, StackNest runs up to 5 automatic fix passes — reading the compiler output and regenerating broken sections until it compiles cleanly.

Download and drop into plugins/

You get a JAR ready for your PaperMC server, plus the full source code. No build tools, no local Java required.

FAQ

Common questions

What is a Paper plugin generator?

A Paper plugin generator is a tool that creates custom plugin code for PaperMC servers. AI-powered generators like StackNest let you describe what you want in plain English, then automatically write the Java source, compile it against the Paper API, and package it as a .jar file.

Which Paper API version does StackNest target?

StackNest defaults to Paper 1.21.4 (the latest stable release) but you can request any version in your prompt. It uses modern Paper API including Adventure text components, PDC for data storage, and all current event hooks.

Does it support Folia?

Yes. Mention Folia in your prompt and StackNest will use the Folia scheduler API (RegionScheduler, GlobalRegionScheduler, EntityScheduler) instead of BukkitScheduler, making the plugin fully compatible with Folia's threaded region system.

Can it generate plugins that use Vault or PlaceholderAPI?

Yes. Just mention Vault, PlaceholderAPI, or any other common Paper dependency in your description. StackNest adds the correct Maven dependency, the soft-depend entry in plugin.yml, and hooks into the API properly.

Do I need to know Java?

No. StackNest is built for server owners and developers who want working plugins without the Java learning curve. That said, the source code is included — experienced developers use StackNest to generate a starting point, then customise from there.
