TeXlyre

A local-first real-time LaTeX and Typst collaboration platform with offline editing capabilities. Built with React, TypeScript, and Yjs for collaborative document editing.

Features:

Real-time Collaboration

TeXlyre enables multi-user editing with live cursors and selections visible across all connected clients. The platform uses Yjs CRDTs for conflict-free synchronization, ensuring that changes from multiple users are automatically merged without conflicts. Communication happens through WebRTC peer-to-peer connections, providing low-latency collaboration without requiring a central server. An integrated chat system allows collaborators to communicate directly within the editing environment.

TeXlyre provides comment and chat features as well for real-time exchanges, reviews, and discussions among collaborators.

LaTeX Compilation

The platform integrates SwiftLaTeX WASM engines to provide in-browser LaTeX compilation without server dependencies. Typst is also supported. Live compilation provides immediate feedback with syntax highlighting and error detection, while the integrated PDF viewer offers zoom, navigation, and side-by-side editing capabilities.

Local-first Architecture

TeXlyre prioritizes data ownership and offline capability. All documents are stored locally using IndexedDB, enabling full offline editing with automatic synchronization when connectivity returns. The File System Access API provides direct folder synchronization for external backup solutions, while project export and import features ensure complete data portability across devices and installations.

File Management and Synchronization

The platform includes a file explorer supporting drag-and-drop operations for various file types including LaTeX sources, images, and data files. Document linking creates connections between collaborative documents and static files, enabling editing in real-time. FilePizza integration provides secure peer-to-peer file sharing between collaborators, allowing large file transfers without intermediary servers.
