Test servers in seconds. Share them in one click.
Spin up a throwaway Paper, Folia, Purpur or Velocity server with your plugins, poke at it with bots, then hand a friend a public address. No port forwarding, no leftover folders.
Version 0.1.23. Free. Windows 10 and 11. Sign in only to publish.
Everything you do by hand to test a plugin, done for you.
A server in seconds
Paper, Folia, Purpur or a Velocity network on any version. It cleans itself up after 30 minutes unless you keep it.
Publish without port forwarding
One click gives your server a public name for two hours. Players reach it through our relay; your home address stays private.
Bots that play
Summon bots that walk, chat, follow you and fish, to load-test a plugin without rounding up friends.
Every version at once
Run the same plugins on up to eight versions side by side and see where something breaks.
Console, files and players
A console with completion, a file editor with diffs, and live player views: drag items around an inventory, edit enchants, teleport.
Drive it with AI
Built-in MCP lets agents like Claude Code deploy servers, read the console and run bots for you.
From installer to a running server in three steps.
Install it
Download and run the installer. No Java yet? The app downloads Java 25 for you.
Add your plugins
Pick your plugin jars, the software and the version. Tick Lattice if you use it.
Deploy and share
Test in the console, with bots or in game. Press Publish when a friend should join.
Good to know.
Is it free?
Yes. The Testbench is free to use, publishing included, within fair limits per account.
Why do I need an account to publish?
A public name is a door into your PC, so each one is tied to an account and expires on its own. Everything else works signed out.
Windows warned me about the installer.
New installers are flagged until enough people have run them. Choose More info, then Run anyway.
Does it work with Lattice?
Tick Lattice when you deploy and the newest version is added for you, with your key, so the modules you own load.
Your next test server is one click away.
Free, for Windows. An account is only needed to publish.
