This is a comprehensive guide on how to download Fabric and mods for it. It also provides direct links to many mods that you may find useful.

Introduction

If you want more information on Fabric, why Forge/OptiFine are not recommended, or need help downloading Fabric and mods for it, click on the Introduction drop down below. If you are just here to see the mods list, continue to the next section.

Introduction

The Situation

So, you've been playing 1.8.9 for the past 8.5 years and are ready to see what 1.21 has to offer. Your first thought may be to download and install Forge and then add OptiFine as a mod, but this could not be further from the best choice. As Mojang has been rolling out releases, they've also been decreasing performance with every version, and neither Forge nor OptiFine are really able to bring back even a speck of that performance we see in 1.12 and below. However, another mod loader, Fabric, which is lightweight and easier to develop for, has created an amazing community in which many of its members focus on helping optimize the game to its greatest potential.

Why no longer OptiFine?

OptiFine no longer provides the benefit that it once did on older versions of the game. As the years have gone by and Minecraft's code has changed, OptiFine has been continuing to completely overwrite major parts of Minecraft's code. Because OptiFine is closed source, it has become increasingly harder for modders to provide OptiFine compatibility. OptiFine also uses outdated formats for many of its features, including MCPatcher and its confusing and outdated settings menu. Many members in the Fabric community have taken it upon themselves to create better performance enhancing mods which surpass OptiFine, as well as provide alternatives to many of OptiFine's iconic features.

While there is a Fabric compatibility layer for OptiFine known as OptiFabric, it is unsupported by many of the mods on the list, with some outright preventing the game from loading if OptiFabric is present. Therefore, consider all mods in this list to be incompatible with OptiFabric.

Why no longer Forge?

Forge has always been less than ideal for performance due to its large overhead for server-sided modding, which is not necessary for users wishing for a vanilla compatible experience. Fabric on the other hand is extremely lightweight and is practically identical to vanilla. It's also considered to be much easier to make mods for.

Unlike Fabric, which aims to modify vanilla as little as possible, Forge makes a lot of changes that simply are not beneficial for our usecases. For example, for several months and spanning several Minecraft versions, there was a bug in Forge that gave the player 4-5 block reach in survival mode, effectively banning every Forge player playing on any server with an anticheat at that time. Due to Fabric's goal of being as uninvasive as possible, issues like this won't arise with Fabric Loader, and if they did, would be fixed much quicker.

Installing Fabric

Due to many issues with the official Minecraft launcher, we will not be using it. We will be using the ModrinthApp instead, which is a much improved launcher that has many more features than the official Minecraft launcher and is made with mods in mind.

Install the app from the Modrinth page and continue on with the installation. The Modrinth app should walk you through how to log in, create profiles, and install mods.

Once this is completed and you are back at the main home page, press the create profile button on the bottom left (the green plus sign). Select any icon and give it any name you want, set the loader to Fabric, and select the game version to 1.21.

Downloading and Installing Mods for Fabric

This list currently consists of three different sources for mod downloads: Modrinth, GitHub, and CurseForge. This section will explain how to download mods from each of them.

Automatic Installation:

  • You can simply click on the instance go to the Content tab and press the "Add content" button in the top right to search Modrinth directly inside the launcher.

  • GitHub and CurseForge mods will require manual installation. The Content tab has a dropdown next to the Add content button to add from file. Use that to add the mods you have downloaded.

Manual Download

  • Modrinth:

    • On the mod's page, click on the Versions tab. From there, you can see all versions of the mod. Make sure you download the correct one based on the Minecraft version and mod loader, click on the download icon for the newest version of the mod that fits both previous criteria.
  • GitHub:

    • For your convenience, all GitHub links lead directly to the latest version of the mod. From here, click on the Assets drop down if needed, then download the jar that does not include -sources or -dev in the name.
      • If a link does not redirect you to the latest version but rather the main page, on the right side of the page, you should find a tag icon with the latest version.
  • CurseForge:

    • Click on the Files tab. Look for the versions of the mod with the Minecraft version you desire and is for the Fabric mod loader, and download the latest one. You can also press the View All button, then sort by mod loader or Minecraft version to make finding the correct jar easier.

Mods

Dependencies

Dependencies are smaller mods that main mods rely on to function. If you are using Modrinth launcher, these should be automatically downloaded for you when you download mods within the launcher, and you don't need to worry about it.

Dependencies are going through a makeover where along with a giant list at the top, mods will specify their required dependencies in the table itself. This is currently only implemented for a few categories.

Mod Required for Author
Fabric API Most mods Fabric Team
Fabric Language Kotlin Several mods (that use kotlin) Fabric Team
Mod Menu Most mods in order to access config in game. Terraformers
Indium Several mods comp500
Architectury Several mods Shedaniel
Cloth Config Several mods Shedaniel
YetAnotherConfigLib Several mods isXander
MaLiLib Litematica, MiniHUD Matti Ruohonen

Performance

These are mods that are needed for playing the latest versions of Minecraft at a reasonable FPS. These will also help decrease frame times, hopefully eliminating spikes or stuttering.

Mod Description Author Dependencies Incompatabilities Notes
Sodium An all around performance mod, Sodium allows users to play the latest versions of Minecraft with high FPS, completely outperforming OptiFine, with some users seeing up to 8x their vanilla frames. Sodium also drastically improve visuals, providing a much better gameplay experience. CaffeineMC
Iris A shader loader that allows users to load up their favorite OptiFine shaderpacks, but with much higher FPS. Iris also provides performance enhancements when not using shaders, making it great for all users. Iris Team Sodium
Lithium Helps improve the performance of many vanilla systems without changing their mechanics. CaffeineMC
Exordium (No 1.21 Yet) Caps the FPS of certain HUD elements that do not need to be updated every frame. tr7zw Fabric API May break some HUD elements from other mods.
Enhanced Block Entities Improves block entities by making them used baked models instead, allowing for better performance, visuals (via better smoothlighting), and better resource pack customizability. FoundationGames Fabric API
FerriteCore Helps reduce the amount of memory the game takes up. This may make a big difference for larger modpacks as well. malte0811
Entity Culling Culls entities that you cannot see, increasing FPS. While Sodium already does this, this mod is much more thorough in which entities can be culled. tr7zw
ImmediatelyFast Improves the immediate mode rendering performance. RaphiMC
ModernFix ModernFix is an all-in-one mod that improves performance, reduces memory usage, and fixes many bugs in modern Minecraft versions without majorly compromising the game experience. embeddedt
Dynamic FPS Reduces your FPS when tabbed out of the game, therefore reducing your system load. juliand665 Fabric API
Lazy Language Loader Improves loading times when changing your language in game by only reloading the required resources. chachy
Sodium Extra Allows you to half the resolution on Apple's Retina displays and also adds most of OptiFine's performance features such as toggles for animations, particles, rain/snow, clouds, sky and biome colors, and more, as well as some custom ones. FlashyReese Fabric API, Sodium
Debugify Fixes several bugs in Minecraft, including a few which can effect performance. This will fix lag spikes when crossing chunks and when clicking on links or the resource pack folder button, reduces time it takes to load into a world, and fixes entity collision checks being needlessly calculated client side. isXander YACL
Audio Engine Tweaks (No 1.21 Yet) Fixes the sound pool overloading, allowing for sounds to continue playing at all time and without log spam. mattymatty97
Ksyxis Reduces world loading times. VidTu
FastQuit Allows you to go back to the title screen while the world is still loading or saving. It is done in a way that prevents world corruption. KingContaria Fabric API, Cloth Config
Noxesium Contains several smaller performance improvements and also has many visual bug fixes for the MCCI server. Noxcrew Fabric API
Remove Reloading Screen Allows you to access other parts of the game by removing the reload screen except for the progress bar. dima_dencep Fabric API, Cloth Config
C2ME C2ME is an experimental mod that attempts to multithread chunk generation, I/O, and loading. RelativityMC
Very Many Players VMP attempts to alleviate the strain on servers when there are a large amount of players. RelativityMC
Early Loading Screen Allows the game to create a game window earlier, allowing you to stop the game much faster if needed. Ishland May cause crashes when starting the game. If your game instantly crashes, try disabling this mod.
Noisium Optimizes world generation when generating new chunks. Steveplays
Particle Core Several optimizations to particles in Minecraft and customization of particle rendering, i.e., being able to turn them on/off individually and putting them in a reduced state. fzzyhmstrs Fabric API, Fabric Language Kotlin
Force Close Loading Screen Instantly closes the loading terrain screen on world changing and drastically reduces the resource pack loading screen duration. kennytv

Other Performance Mods

These are other performance mods that one may prefer to use, but are not required. It is neither recommended or unrecommended, and is up to the player to decide given their use-case.

Mod Description Author Dependencies Incompatabilities Notes
Nvidium Nvidium uses NVIDIA only OpenGL extensions to greatly improve the game's performance. This mod will not work on AMD. It has a few graphical glitches and could lead to crashes, as the mod is still in beta and not considered stable yet. The mod will also disable itself whenever Iris shaders are enabled or if the required OpenGL extensions are not available. MCRcortex Sodium Chunks won't fade when using Chunks Fade In.
Fadeless Removes transitions such as the fading animation that Mojang added between their splash screens. This may provide a smoother experience if the fade is choppy on a low end machine or allow people to access certain menus quicker if they do not like the small wait time. This mod is made partially redundant by Remove Loading Screen. DerpDerpling & UltimateBoomer Fabric API
Krypton This mod is bannable on Hypixel and most likely other servers. Although it is probably not detectable, it is still against Hypixel's rules and the mod developer does not recommend using it on Hypixel. However, this mod works great for private servers. Krypton optimizes network stacking and entity tracking, as well as other micro-optimizations. astei
Methane Completely kills the light engine, providing permanent fullbright and improved FPS. Disable when using shaders. Allows you to disable some fog such as powdered snow fog and lava fog, which may be considered as an unfair advantage on some servers. AnOpenSauceDev Fabric API, Cloth Config May cause issues when using some shaders. Disable Methane if there are visual glitches.

These are mods that I personally recommend due to their usefulness. While they may not boost performance, they are mostly quality of life mods meant to better your experience.
