Overview
Easy setup, on-demand scalability
Get started in local mode in minutes. Then, scale up as far and as fast as you need.
Fast and efficient processes
Scale without slowdowns, thanks to shared, reusable data and as-needed downloads.
Free branching
Quickly and easily create, manage, and sync branches to freely experiment, iterate, and release.
History you can trust
Confidently track and manage revisions with Lore's verifiable tamper-evident source of truth.
Intuitive interface
Enjoy complete one-to-one access to the full Lore functionality via the CLI.
Full-surface API
Extend, customize, and integrate Lore via C/C++, C#, Rust, Go, Python, or JavaScript.
Lore’s architecture
Lore is a centralized, content-addressed version control system that represents repository state as Merkle trees and an immutable revision chain, optimized for binary-first storage, deduplication, and sparse/on-demand data hydration at scale.

Content-addressed storage
Repository data is stored and referenced by content hash in a Merkle tree, enabling fast comparisons, integrity checks, and reuse across history and branches.
Immutable revision chain
A revision's hash signature is derived from its revision state, including parent revision hashes and contained data hashes, forming an immutable chain with cryptographic integrity.
Chunked storage for large files
Files are stored as reusable chunks with indexed lookup, reducing duplication and enabling efficient updates and transfer for large binary assets.
On-demand hydration and sparse workspaces
Workspaces can stay lightweight by fetching file data only when needed, so you don't have to download everything up front.
Centralized service with caching
A service-backed architecture uses caching in front of durable storage to scale throughput for large teams and repositories.
Lightweight branches and fast switching
Branches are lightweight mutable references, so creating and switching branches is low-overhead without duplication of underlying data.

Fully open source
At Epic, we believe a truly open ecosystem won’t be built by any one company, but collectively and collaboratively using open standards. That’s why Lore is fully open source and released under an MIT license.
Let’s build the version control system of the future in the open, learning from each other’s needs and ideas from the start. Come join us!
