Embeddium

Embeddium is a free Minecraft mod focused on rendering performance on the game client. It uses a multi-loader setup and is listed for Minecraft 1.16.5, 1.18.2, 1.19.2, versions 1.20.1 through 1.20.6, versions 1.21 through 1.21.1, and version 1.21.4. The mod does not require Sodium. Its stated scope is client-side use, so it is intended to run with the player’s Minecraft installation rather than as dedicated server software. Dedicated server support is not provided. Embeddium is available through Modrinth with a free plan. The main selection check is version matching: users need one of the listed Minecraft releases. The multi-loader designation indicates that it supports more than one mod-loading environment. Because its focus is rendering, it is aimed at installations where client rendering performance is the relevant need. Server operators should distinguish that client scope from dedicated-server requirements when deciding whether it fits their setup.

It suits Minecraft players using one of the listed versions who want a client-side rendering-focused mod. It is not intended for dedicated server support.
