TecniLauncher supports four mod loader types. Each has different mod compatibility and performance characteristics. You select a loader when creating a profile, and it cannot be changed afterward — create a new profile if you need a different loader.
Vanilla
Forge
Fabric
NeoForge
Vanilla runs pure, unmodified Minecraft with no mod loader installed. It is the simplest option and requires no additional setup.Best for:
- Vanilla survival or creative play
- Joining servers that do not require mods
- Testing vanilla behavior or resource packs
Setup: Select Vanilla when creating a profile. No additional installation steps are needed. The game launches using the standard Minecraft runtime. Forge is the longest-established Minecraft modding platform and has the largest mod ecosystem, especially for versions 1.7.10 through 1.20.x. Most large modpacks and tech mods are built for Forge.Best for:
- Large modpacks with many mods
- Tech mods (Create, Applied Energistics, Thermal Expansion, etc.)
- Versions 1.7.10 through 1.20.x
Setup: Select Forge when creating a profile. TecniLauncher installs the Forge runtime automatically on first launch using CmlLib.Core.Installer.Forge. You do not need to download anything manually. Fabric is a lightweight, modular loader that updates quickly after new Minecraft releases. It is the preferred choice for performance-focused mods and newer Minecraft versions.Best for:
- Performance mods (Sodium, Lithium, Iris)
- Newer Minecraft versions where Forge support may lag
- Projects that prioritize fast updates
Setup: Select Fabric when creating a profile. TecniLauncher downloads the Fabric loader profile automatically from meta.fabricmc.net. The installed version identifier follows this format:fabric-loader-{loaderVersion}-{mcVersion}
fabric-loader-0.15.11-1.20.1 NeoForge is a modern fork of Forge with active development and improved internals. It is designed for Minecraft 1.20.1 and later and maintains broad compatibility with Forge mods.Best for:
- Modern modpacks targeting 1.20.1 and newer
- Projects transitioning away from legacy Forge
- Mod developers building for the current ecosystem
Setup: Select NeoForge when creating a profile. Setup works the same way as Forge — TecniLauncher installs the NeoForge runtime automatically on first launch using CmlLib.Core.Installer.NeoForge. Choosing the right loader
| Use case | Recommended loader |
|---|
| Mods targeting 1.7.10–1.16.x | Forge |
| Performance mods (Sodium, Lithium, Iris) | Fabric |
| Large modpacks on 1.20.1+ | NeoForge or Forge |
| Pure vanilla — no mods | Vanilla |
Mods are built for a specific loader. A Forge mod will not load in a Fabric profile, and vice versa. Always check a mod’s supported loaders on its Modrinth or CurseForge page before installing.
Loader version selection
When creating a Fabric profile, TecniLauncher queries the Fabric metadata API and presents the available loader versions for your chosen Minecraft version:
