MantleJS
by Pelemenguin
MantleJS is an optimization Minecraft mod from Pelemenguin with 373 downloads on the Orca catalog. It runs on Forge, so it slots into a matching Minecraft profile without hand-patching anything. MantleJS is free to download and free to host on Orca: press Play and Orca launches Minecraft with MantleJS already installed, or host it on a free server to play with 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 MantleJS along with the loader and Minecraft version it needs, then you and your friends are playing in minutes.

How to install MantleJS
Two ways to add MantleJS to Minecraft. One takes a click.
- Click Play below. Orca installs MantleJS with Forge and the right Minecraft version, then launches straight into the game.
That’s it. Nothing to download or configure.
- Download the latest MantleJS file from Modrinth for your Minecraft version.
- Install Forge 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 MantleJS depends on (the Modrinth page lists them) into the same folder, then start Minecraft on the Forge profile.
