Epic Games unveiled Lore on September 6, 2026, a centralized, content-addressed version control system designed to handle large binary files common in game and multimedia development [1]. Lore represents repository state as Merkle trees with an immutable revision chain, combining centralized server features with open specifications [2, 1].
The system supports fragment-level storage deduplication, sparse on-demand data hydration, free branching, and offline use without network round trips for typical editing operations. These features aim to overcome limitations found in Git and existing large-file version control solutions [1].
Lore is fully open source and distributed under the MIT license, with all code accessible on Epic Games' GitHub repository [1, 2]. Epic Games said, "No existing system was designed for the combination of constraints that large game and entertainment projects require: arbitrary content types, multi-axis scale, multi-tenant safety, and a fully open specification and license" [1].
Developers can explore Lore repositories on Epic Games’ GitHub page, inviting community contributions and adoption [2]. The launch targets modern studios struggling with version control for large unstructured assets in games and multimedia.
Lore’s release marks an important step toward more efficient and flexible handling of large binary data in source control. Epic Games plans to build on this foundation with ongoing updates and improvements.
