Y-Octo

Y-Octo is a high-performance CRDT implementation compatible with yjs.

Introduction

Y-Octo is a tiny, ultra-fast CRDT collaboration library built for all major platforms. Developers can use Y-Octo as the Single source of truth for their application state, naturally turning the application into a local-first collaborative app.

Y-Octo also has interoperability and binary compatibility with yjs. Developers can use yjs to develop local-first web applications and collaborate with Y-Octo in native apps alongside web apps.
