Project Overview: Aspen

Purpose

Aspen (formerly known as Lonni) is a cross-platform real-time collaborative application built for macOS and iPad. It demonstrates real-time CRDT (Conflict-free Replicated Data Type) synchronization with Apple Pencil input support.

Key Features

Real-time collaborative drawing/interaction with Apple Pencil support
P2P synchronization using CRDTs over iroh-gossip protocol
Cross-platform: macOS desktop and iOS/iPadOS
3D rendering using Bevy game engine
Persistent local storage with SQLite
Session management for multi-user collaboration

Target Platforms

macOS (desktop application)
iOS/iPadOS (with Apple Pencil support)
Uses separate executors for each platform

Architecture

The application uses a workspace structure with multiple crates:

app - Main application entry point and UI
libmarathon - Core library with engine, networking, persistence
sync-macros - Procedural macros for synchronization
xtask - Build automation tasks

Development Status

Active development with RFCs for major design decisions. See docs/rfcs/ for architectural documentation.
