The Problem
Complex design tools have too much overhead for quick collaborative brainstorming sessions. Teams needed a lightweight alternative for rapid visual collaboration without full-featured application bloat.
What We Built
Cranva is a minimalist collaborative canvas using WebRTC for real-time peer-to-peer sync and Canvas API for smooth drawing. Just enough features for productive collaboration without bloat. No account required to join.
