Describe what you want in plain English. StackNest generates the code, compiles it, and hands you a working .jar — ready to drop into your server.
Free tier · No credit card · 3 plugins/month
StackNest handles everything a plugin developer would do — writing, compiling, debugging, and packaging.
Write what you want in plain English — as detailed or as brief as you like. Include platforms (Paper, Velocity, Folia), dependencies (Vault, PlaceholderAPI), commands, permissions, GUI layouts, and any specific behaviour. The more detail you give, the more precisely it's built.
A specialised AI model writes the full plugin: the main class, all supporting classes (GUIs, commands, listeners, managers), plugin.yml, and a pom.xml with the correct Paper API version and any required dependencies.
The source is compiled server-side. If there are compile errors, StackNest runs up to 5 automatic fix passes — sending the error log back to the AI and regenerating the broken section. You won't see a plugin unless it compiled cleanly.
You get a compiled JAR, the full source code, and links to the public gallery entry. Drop the JAR into your plugins/ folder and restart or reload the server.
Not just code stubs — complete, working plugins with all the classes and files a real plugin needs.
Custom slash commands with argument parsing, tab-completion, per-command permission nodes, and player/console handling.
Inventory menus with slots, icons, pagination, click handlers, and confirmation dialogs. Kit selectors, shop menus, admin panels — any GUI layout.
Per-player data saved to YAML files or SQLite using HikariCP connection pooling. Persistent across server restarts with async read/write to avoid TPS lag.
Vault API integration for give/take/check player balances. Works with EssentialsX, CMI, and any other Vault-compatible economy plugin.
Repeating and delayed tasks for countdowns, auto-saves, arena resets, and timed game events. Uses Bukkit's scheduler with async support.
Animated scoreboards with per-player lines, persistent sidebar displays, and BossBar progress indicators for countdowns, health, and cooldowns.
Expand and provide PlaceholderAPI placeholders so your plugin's data surfaces in scoreboards, chat, and TAB from other plugins.
Generate for Paper, Spigot, Folia (multi-threaded), and Velocity proxy plugins. Select your server software and the generated code uses the correct API.
config.yml with configurable messages, values, and feature flags. Reloadable at runtime via a built-in /pluginname reload command.
From simple utility commands to complex game systems — here's what StackNest has generated for real server owners.

A plugin generator is a tool that creates custom Minecraft plugin code for Paper, Spigot, or Bukkit servers. Traditional generators produce code stubs you still need to finish and compile yourself. StackNest goes further — it generates, compiles, and delivers a working JAR with no local setup required.
Yes. The source code is compiled server-side using javac and Maven. If there are compile errors, StackNest automatically runs up to 5 fix passes — feeding the error output back to the AI and regenerating the broken sections. You only see a result once the build is clean.
No. StackNest runs entirely in the browser. You don't need Java, Maven, an IDE, or any other software installed locally. The generation, compilation, and packaging happen on StackNest's servers. You just download the JAR.
ChatGPT and similar general AI assistants generate Java source code but don't compile it — you still need a development environment and will encounter bugs, missing imports, and API misuse that require manual fixes. StackNest is purpose-built for Minecraft plugins: it knows the Paper API, runs a real compilation step, and auto-fixes errors before handing you the result.
The free tier includes 3 plugin generations per month with no credit card required. Paid plans start at £4/month for more generations, longer and more complex plugins, and features like log analysis and deep AI validation.
Yes. Every generation includes the full Java source code, plugin.yml, and pom.xml. You can download the source to review, extend, or learn from it. If you're a developer who wants to understand how Minecraft plugins are built, reading the generated output is a practical starting point.
No Java. No Maven. No setup. Just describe what you want and download the JAR.
