Lore: Next-Generation Version Control | State of Unreal | Unreal Fest Chicago 2026

Watch this clip from the State of Unreal at Unreal Fest Chicago 2026 to learn about Lore, Epic’s next-generation open source version control system.

We decided to build Lore from scratch, designing the data model to meet our requirements from the ground up. We made scalability and performance core tenets from day one.

We’re releasing Lore as open source today. All source code, along with documentation of data formats and protocols are released under an MIT license and free to use. This release should not be viewed as a complete package, but as an invitation to you to extend it, challenge it, and help shape it into something even more powerful, together.
