Server Plugins

Build custom Minecraft plugins. No developer required.

Your server deserves custom features - not a $200 commission and a week of waiting. Describe the plugin in plain English and Foundry's AI builds it against the real Paper API, tests it on a live local server, and hands you a standard .jar you fully own.

How It Works

Idea to running plugin in minutes

01

Describe the plugin

Plain English: "A /home system with a configurable cooldown, and a welcome message players see on join." No Java, no API docs, no boilerplate.

02

Foundry AI builds it

Ember writes actual Java against the real Paper API source - commands, listeners, config, permissions - then compiles it and validates the details plugin devs get wrong (unregistered listeners, dead commands, missing config defaults).

03

Test it live in one click

Foundry boots a local Paper test server with the plugin installed and launches a test client that joins it automatically. Use the built-in server console to op yourself and test admin-only behavior.

04

Ship the .jar to your server

The output is a standard plugin .jar with full source code. Drop it in plugins/, restart, and it runs - on Paper, Purpur, or any Spigot-compatible fork. No lock-in.

Why Not Commission?

The math on custom plugins changed

Freelance plugin developers charge $15-100+ per hour, and even a simple custom plugin runs $50-200 with days of back-and-forth. With Foundry you iterate in real time, most plugins cost a few dollars of ingots, and every change is a sentence away - no re-commissioning, no waiting. And because you keep the full source, any developer can pick it up later.

FAQ

Plugin Questions

Foundry builds plugins against the Paper API. They run on Paper servers and Spigot-compatible forks like Purpur and Pufferfish - the software behind the overwhelming majority of Minecraft servers. Versions 1.20 through the latest are supported.
One click. Foundry boots a local Paper test server with your plugin installed, then automatically launches a test client that joins it. A built-in server console lets you run admin commands (op, gamemode, give) while you test. You can also connect your own Minecraft client to localhost.
Every build produces a standard plugin .jar - drop it into your server's plugins/ folder like any other plugin, restart, done. There is no Foundry dependency at runtime; it's a normal Paper plugin you fully own, source code included.
Custom commands, event-driven mechanics (join messages, death handling, block protection), teleport systems, configurable gameplay tweaks, permissions-aware admin tools, scheduled tasks, and more. If it lives in the Paper API, you can describe it and iterate on it.
Foundry is free to download - AI usage runs on ingots, starting at $4.99 for 500. A typical plugin costs a small fraction of a Starter pack, compared to $50-200+ for a commissioned plugin. Ingots never expire.
