Can NeoForge Mods Run on Forge? Compatibility Guide 2026
The short answer: it depends on the Minecraft version. For 1.20.1, most mods are cross-compatible. For 1.20.4 and above, they are not.
The Split Timeline
NeoForge forked from Forge in mid-2023. The split happened during the 1.20.x cycle.
Minecraft 1.20.1 and earlier: Forge and NeoForge share nearly identical APIs at this version. A mod built for Forge 1.20.1 will almost always load on NeoForge 1.20.1. The codebase had not diverged yet.
Minecraft 1.20.2 to 1.20.4: A transition period. Some mods work across both loaders. Others break. NeoForge began introducing API changes that Forge did not adopt.
Minecraft 1.21 and above: Full divergence. NeoForge 1.21+ uses a different package structure, different event system, and different registration approach. A mod compiled for Forge 1.21 will not load on NeoForge 1.21 without being ported.
Is NeoForge the Same as Forge?
No. They share a common ancestor but are separate projects with separate teams. NeoForge has faster update cycles and most of the original Forge developer team. Forge has slower updates and shrinking mod support for newer Minecraft versions.
Compatibility Table
| Minecraft Version | Compatibility | |---|---| | 1.20.1 and earlier | High. Most Forge mods work on NeoForge | | 1.20.2 to 1.20.4 | Partial. Check each mod individually | | 1.21 and above | None. Completely separate projects |
What Modpacks Use What
| Modpack | Version | Loader | |---|---|---| | All The Mods 10 (ATM10) | 1.21.1 | NeoForge | | All The Mods 9 | 1.20.1 | Forge | | Better MC [BMC4] | 1.20.1 | Forge | | RLCraft | 1.12.2 | Forge | | Vault Hunters 3rd Edition | 1.18.2 | Forge |
Most new large modpacks releasing in 2026 target NeoForge. If you are starting fresh, NeoForge is the safer bet for long-term mod support.
Do Not Force-Load Incompatible Mods
Dropping a Forge 1.21 jar into a NeoForge 1.21 mods folder causes crashes on startup. The class names and package paths are different. It will not work.
On Space-Node, you pick your Minecraft version and loader during server creation. The panel installs the correct server jar automatically. Upload mods to /mods via SFTP and start. Minecraft servers from €0.90/GB per month.
