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.

Lore Version Control is an open source version control system designed for scalable data and team workflows. It is optimized for handling both code and large binaries, ensuring a tamper-evident history. The system supports free branching and integrates seamlessly via command line interface (CLI) and APIs. Key features include file versioning and a robust CLI for efficient management.

The basic commands are voluntary very close to Git, not that Lore wants to replace it (because no one can) but because Lore is supposed to offer a cleaner CLI interface (Git has became Frankenstein's program over the years with many functionalities not fully implemented and still not documented) and a good support for binaries with their integrity (plus a backwards compatibility for minor versions).

It's more some modern kinda blockchain-based (because commits with metadata are hash-chained) like many others VCS since Git launch, that is only adapted to very large projects for big companies, where users only download what they need and not the whole project with history, that has no advantage for most projects. Well engineered nonetheless.
