SandSync is a real-time sync platform combining Supabase, PowerSync, and a multi-agent AI pipeline. Built for the PowerSync hackathon. Demonstrates offline-first architecture with real-time conflict resolution and AI-assisted data enrichment. Full demo pipeline with live frontend and deployed API.
Problem
Offline-first apps need reliable sync, conflict handling, and useful data enrichment without fragile glue code.
Experiment
Combine Supabase, PowerSync, and a multi-agent AI pipeline for a hackathon-grade real-time sync product.
Shipped artifact
A deployed frontend and API demonstrating offline-first sync with AI-assisted enrichment.
Result
SandSync became a practical proof of shipping full-stack infrastructure under hackathon constraints.
What we learned
The strongest hackathon projects show an architecture that could survive after the demo.
