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.
• [TODO] Peritext for fine-grind rich text operations
• [TODO] Moveable Tree for directory-like moving operations
• [WIP] Super fast version checkout and undo/redo
