Loro

Loro is a fast CRDT framework with built-in end-to-end encryption ability.

It provides a set of data structures that can automatically sync without any conflict. With end-to-end encryption addon, all data can be encrypted without losing the ability to collaborate with the others. It aims to be the engine for building local-first software.

Why Loro

  • 🚀 It is pretty fast
  • 🔒 [WIP] Security built-in
  • 💻 Syncing data made easy
  • 📜 Preserve all history with low overhead
  • 🪐 [WIP] Time travel the history in milliseconds

Loro supports a variety of data structures and CRDT algorithms.

  • It supports the most used List, Map and Text.
  • [WIP] Peritext for fine-grind rich text operations
  • [TODO] Moveable Tree for directory-like moving operations
  • [WIP] Super fast version checkout and undo/redo

Credits

  • Automerge for its columnar encoding algorithm
  • Yjs for the efficient algorithm of merging blocks
  • Diamond-types for its idea of low-overhead merging algorithm
  • Ink & Switch for Local-first Software and Peritext
