EmbeddedMC
by LowdFX
EmbeddedMC lets players run Paper, Purpur, Folia and Spigot servers directly inside a Minecraft singleplayer instance, from a Fabric mod.
What it does
Players can start Paper, Purpur, Folia and Spigot servers from inside the game, so Bukkit, Spigot and Paper plugins can be tested in singleplayer worlds without a separate server setup. Server JARs are fetched automatically from the official APIs, and each server can be managed as its own instance with separate settings.
The mod is client-side only, so the server runs locally on the player's own machine and other players do not need it. Files are published for Fabric only, for 1.21.11, with 1.0.0 as the latest file released on 2026-01-05. EmbeddedMC is open source under the GNU General Public License v3.0 only. It does not require a separate server install, because the server runs inside the Minecraft instance itself.

Use cases
Testing plugins
Plugin developers can load Bukkit, Spigot and Paper plugins in a singleplayer world to check their behavior before deploying them to a live server.
Trying server setups
Players can try different server software and configurations on their own machine while keeping everything in one game instance.
Who it’s for: The mod suits plugin developers and players who want to test Paper, Purpur, Folia or Spigot setups locally. Server owners who run public servers will not need it for that purpose.
