OptiFine was originally a great mod offering many quality of life improvements for the player in the beginning. However, over the years, its benefits have dwindled and has caused many issues for modders. This is due to Minecraft's codebase improving over the years and OptiFine's aggressiveness towards replacing entire swaths of code while being closed source making it very difficult to figure out why OptiFine has broken another modder's mod. Also worth noting that OptiFine natively doesn't support Fabric and it's hard to maintain OptiFabric.
In the modern Minecraft era, with Fabric's community effort, modders have begun to create alternatives for most of OptiFine's features to allow players to maintain better performance, better mod compatibility, and better support.
OptiFabric: A note about the 1.16 crashes
This list will list recommended OptiFine alternatives by LambdAurora (and edited by PseudoDistant), so it has some requirements for mods to be listed here:
- They must be publicly available, if it's only accessible through Discord they are not eligible.
- Mods must respect the Minecraft's EULA.
- Mods must not refer to a cheat client.
- Mods that change gameplay in a way (e.g. zoom) that have a way for servers to disable them will be favored.
- Free and open-source mods are favored.
You can contribute to this list by opening a pull request on the data branch via GitHub.

This mod delays the initialization of DFU by initializing only when needed, if you're playing only on multiplayer it'll never get initialized for example.

As of 1.16.2 and above, this is now a vanilla feature under the accessibility settings. If you are playing in 1.16.2 or above, the mods for this feature are irrelevant.
These are client-only mods that prevent Minecraft from changing the FOV in all situations.
Sodium and Canvas Renderer are incompatible.
Some mods require the Fabric Renderer API to work, Canvas supports it, but Sodium will not support it by default, Indium is required to support it.
- custom entity models (might come in Vanilla to an unknown date?) currently incompletely replaced: current existing implementations are very hardcoded to Vanilla entities
- Emissive block textures (in a compatible way with rendering mods, FREX offer a way but it's not OptiFine compatible, FREX is a rendering API).
