COSTAR
COSTAR is a Minecraft mod with 686 downloads on the Orca catalog. It runs on Legacy-fabric and Ornithe, so it slots into a matching Minecraft profile without hand-patching anything. COSTAR is free to download and free to host on Orca: host it on a free Orca server and invite your friends. There is no control panel and no config files to edit, and no command line to learn. Describe what you want in plain English and Orca installs COSTAR along with the loader and Minecraft version it needs, then you and your friends are playing in minutes.

How to install COSTAR
Two ways to add COSTAR to Minecraft. One takes a click.
- Click Host below. Orca spins up a free server with COSTAR already installed, ready for you and your friends.
That’s it. Nothing to download or configure.
- Download the latest COSTAR file from Modrinth for your Minecraft version.
- Install Legacy-fabric and Ornithe and launch Minecraft once so the loader profile is created.
- Drop the downloaded .jar into your mods folder (the mods folder inside .minecraft, or your server's mods folder).
- Add any libraries COSTAR depends on (the Modrinth page lists them) into the same folder, then start Minecraft on the Legacy-fabric and Ornithe profile.
