Which NeoForge Version Should I Use for My Minecraft Version?

Use the NeoForge version whose number matches your Minecraft version: NeoForge 21.11 targets Minecraft 1.21.11, NeoForge 21.9 targets Minecraft 1.21.9, and NeoForge 21.6 targets Minecraft 1.21.6. If you are on a snapshot rather than a release, early NeoForge builds exist for 26.1 snapshots. The installer page lets you pick your Minecraft version and then shows the matching NeoForge version, so you do not have to guess the pairing.

How the version pairing works

NeoForge release announcements on neoforged.net consistently name both versions together, which makes the mapping easy to read:

The pattern is that the NeoForge number tracks the Minecraft number rather than being an independent sequence, so a higher Minecraft version generally means a higher NeoForge version.

Snapshots and pre-release Minecraft versions

If you play on a snapshot, check the news feed before assuming there is no build. The project published early NeoForge builds for Minecraft 26.1-snapshot-1, announced in December 2025, ahead of the full "NeoForge for Minecraft 26.1" post in March 2026. Snapshot builds are early, so expect them to be aimed at testing rather than stable play.

Finding the right installer

The installer page on neoforged.net has two selectors: Minecraft Version and NeoForge Version. Choosing your Minecraft version narrows the available NeoForge versions, which is the most reliable way to confirm a match. If you are setting up mod development rather than just running the game, the same page links to the Mod Generator for new projects and the MDK list for updating an existing build script.

What to check before you commit

• Confirm the Minecraft version you actually run, including whether it is a release or a snapshot.
• Match it against the release posts above, or use the installer selectors to verify.
• If you maintain a mod, check the MDK list for build-script changes, since NeoForge has shipped breaking changes between releases — the transfer API rework in NeoForge 21.9 is one example that required migration.
• If you run a server, note that NeoForge has published guidance on mitigating network vulnerabilities in serverbound packets, which is relevant when you accept connections from untrusted clients.

The pairing is the decision: pick the NeoForge release that names your Minecraft version, and use the installer page selectors to confirm it before downloading.
