Pastel

Utilities

Pastel turns a Modrinth modpack into a managed dedicated server. It downloads and verifies server-side pack files, installs the required mod loader and Java runtime, starts Minecraft, and keeps the server aligned with the pack version you selected. Visit Pastel on kaf.sh for the short product overview.

Pastel prepares a Modrinth pack’s files, loader, and Java runtime, then runs the dedicated Minecraft server. — One pack describes the server Pastel prepares and runs.

Set up a server

Install a Modrinth pack from its slug, project page, .mrpack URL, local archive, or Maven coordinate.

Operate it

Refresh files, preview updates, follow the live console, and stop the server gracefully.

Recover from crashes

Background servers restart after unexpected crashes, while clean shutdowns and startup failures remain stopped.

Manage Java

Pastel selects a suitable system Java or installs a checksum-verified Temurin runtime under the server directory.

Quick start

On Linux or macOS, open an empty server directory and install Pastel:

curl -fsSL https://kaf.sh/pastel/install.sh | sh

Now install and start the pack:

./pastel install aristea
./pastel run
./pastel console

install creates server.pastel and applies the pack. run starts a background server, and console follows the live log while accepting Minecraft server commands. On Windows, download the Windows archive and use .\pastel.exe in PowerShell.

Minecraft EULA

Starting a Minecraft server with Pastel indicates that you agree to Mojang's Minecraft EULA. Pastel writes eula=true when it starts the server.

Platform support

Platform	Install and refresh	Run	Background console
macOS	Yes	Yes	Yes
Linux	Yes	Yes	Yes
Windows	Yes	Yes	Yes

Background servers, console commands, crash restarts, and graceful shutdown work on all three platforms. Windows uses a named pipe for console input. Foreground mode is available everywhere with pastel run -f.
