Fabric vs Forge: Which Mod Loader Should You Use?

If you are new to Minecraft modding, you will quickly run into a choice that used to be simple but has gotten genuinely complicated: should you install Forge or Fabric? Both are free, both support a massive library of mods, and both are actively maintained. But they are very different tools suited to different types of players. Here is a practical breakdown to help you choose.

What is Forge?

Forge is the original Minecraft mod loader, launched in 2011. Its defining characteristic is its huge legacy library — if a mod was created before 2019, there is almost certainly a Forge version of it. Forge is particularly dominant for large modpacks and total-conversion mods like RLCraft, Feed the Beast (FTB), and Vault Hunters. If your goal is to play any popular pre-built modpack from a launcher like CurseForge or ATLauncher, you will almost certainly be using Forge.

The trade-off is that Forge is heavier and slower to update. When Mojang releases a major Minecraft version, it can take Forge several weeks or months to release a stable build. Forge also has a reputation for longer startup times and occasional mod conflicts, especially when mixing many mods from different developers.

What is Fabric?

Fabric is a lightweight, modern mod loader first released in 2018. Its design philosophy is to be minimal — Fabric itself does very little; most functionality comes from individual mods like Fabric API. This makes it extremely fast to update when new Minecraft versions release, often within days. Fabric is the preferred loader for performance-focused mods like Sodium, Lithium, Starlight, and Iris Shaders, which is why it is the go-to choice if you care about frame rates.

The downside is that Fabric has a smaller legacy mod library than Forge, and many older or complex mods simply don't have Fabric ports. If you want to play a huge kitchen-sink modpack with hundreds of interconnected mods, Forge is more likely to have what you need.

Which One Should You Choose?

• Choose Fabric if you want shaders, performance optimization, and modern mods. Fabric + Sodium + Iris + Lithium is the current gold standard for getting the most out of Minecraft on any hardware.
• Choose Forge if you want to play an established modpack (RLCraft, All the Mods, etc.) or need access to a specific large mod like Thaumcraft or Twilight Forest that only has a Forge release.
• Note on NeoForge: In 2023, a fork of Forge called NeoForge was created by most of the original Forge team. Many new mods now target NeoForge instead of Forge proper. If you are setting up a new Forge-style modpack, check whether NeoForge might be the better option going forward.

The good news: you can have both installed on your machine simultaneously. Just create separate launcher profiles for each and manage your mods per-profile. This way, you never have to permanently pick a side.
