Offline-first code editor that syncs flawlessly post-ZESCO outages.
Zambian developers suffer constant power outages from ZESCO load shedding, forcing them to rely on expensive generators and delaying critical project timelines.
OfflineSync is a PWA code editor optimized for Zambian devs, storing all changes locally during blackouts. Auto-syncs to GitHub/Supabase on reconnect, with conflict resolution. Work uninterrupted, no generators needed.
