In their own words
Krypton
Krypton is a free Fabric mod that optimizes Minecraft networking and entity tracking, with its performance work directed mainly at servers. It works on both clients and servers, including dedicated servers. Its network handlers are based on optimized Netty handlers from the Velocity proxy, using native code where appropriate. Flush consolidation is intended to reduce server CPU use and tick times and lessen the impact of speculative-execution hardware vulnerabilities. Other small optimizations target memory use and packet serialization speed. Krypton is tuned for Linux, though it should work wherever Minecraft can run. CurseForge lists Fabric and Quilt as supported loaders. The project aims to work with Fabric API, Lithium, and Sodium; compatibility with other mods is best effort. It is licensed under LGPL-3.0-only, and the maker does not guarantee stability, compatibility, or support for every setup. The project is described as feature-stable, while updates for newer Minecraft versions depend on the maker's availability and need. Listed compatibility includes Minecraft Java Edition versions 1.16.2 through 1.16.5, 1.17.x, 1.18.1 through 1.18.2, 1.19.x, 1.20.x, 1.21.x, and 26.1 through 26.3.
VulkanMod
VulkanMod is a free Minecraft client mod that replaces the default OpenGL renderer with a Vulkan-based engine intended to improve performance. Its listed optimizations cover terrain rendering, chunk building and entities, alongside reduced CPU and GPU overhead. It also supports native Wayland on Linux and windowed fullscreen mode. Installation requires Fabric, followed by placing VulkanMod.jar in the .minecraft/mods folder, and a GPU with at least Vulkan 1.2 support. The project lists Minecraft versions 1.21.3, 1.21.4, 1.21.5, 1.21.10 and 1.21.11. Shader support is not available, and there is no estimated release date; the README points users to Beryl for shaders. Mods that use OpenGL calls are unsupported, including Sodium, Iris Shaders, Create and Distant Horizons. Release 0.6.0 notes a terrain-rendering improvement when backface culling is enabled, an update checker, and fixes for alpha cutout sampling and a memory leak.
