## What it is
Lore is an open source, next-generation version control system built by Epic Games in Rust, designed for scalability of data and teams. It is optimized for projects combining code with large binary assets, using content-addressed Merkle tree storage, an immutable revision chain, and on-demand data hydration.

## Use cases
- version control for game projects with large binary assets
- track revisions of code and art files together
- scale version control to huge repositories and teams
- deduplicate large files across history and branches
- branch and merge freely for experimentation
- tamper-evident verifiable revision history
- sparse on-demand download of large files

## When to choose
- your project mixes source code with large binary assets like games or film
- you need a centralized VCS that scales beyond Git's limits for big files
- you want content-addressed storage with deduplication and integrity guarantees
- you need a CLI-first VCS with APIs in multiple languages

## When to avoid
- you need a battle-tested, production-stable tool — Lore is pre-1.0 with changing formats and APIs
- you rely on Git's decentralized workflow and ecosystem
- your project is small and Git already serves you well
- you need a GUI client today — the desktop client is still on the roadmap
