Epic Games launches Lore, an open source version control system designed for scalability

Epic Games has introduced Lore, an open source version control system engineered for projects combining code with large binary assets. This launch targets studios and creators working on games or entertainment requiring solutions that scale across both data volume and multidisciplinary teams.

Lore is built as a centralized, content-addressed platform. It uses Merkle trees to represent repository state and maintains changes through an immutable revision chain. These technical choices enable binary-first storage, automatic deduplication, and support for sparse or on-demand data hydration across vast repositories.

While setup can begin in a local mode within minutes, teams can expand their use of Lore with on-demand scalability, ensuring that onboarding and growth require minimal disruption. Performance features such as shared data reuse and as-needed asset downloads help prevent bottlenecks during periods of intense activity or large team collaboration.

In addition, Lore allows developers to rapidly branch and merge without restrictions, supporting free experimentation and iteration. Revision history is tamper-evident, giving teams confidence in tracking source changes. Lore offers a full command-line interface and a public API that supports C, C++, C#, Rust, Go, Python, and JavaScript for broader automation and integration opportunities.
