Multi-device offline collaboration hub for hotel teams during blackouts.
Tanzanian hoteliers lose revenue from frequent electricity blackouts that crash their cloud-based property management systems, forcing manual operations during peak tourist seasons.
OffGridHub provides a shared dashboard that syncs realtime across devices using local-first tech, falling back to offline mode during outages. Teams edit reservations collaboratively via phones/laptops on battery, with Supabase handling merges on reconnect. Purpose-built for Tanzanian hotels to maintain peak-season ops without cloud dependency.
