Perceived zero-lag code collab with optimistic deltas.
Remote developers are frustrated with laggy real-time code collaboration tools that make pair programming sessions unproductive.
CodeEcho applies optimistic updates and compressed delta syncing to make changes appear instant, even on high-latency networks. AI predicts common edits to pre-apply them. Sessions include built-in chat and terminal sharing for full pair flow.
