Technical Logic

Vita Board follows a client–server architecture with a mobile-first, offline-capable design. All user data is stored locally using Hive to ensure instant access and reliability even without network connectivity. The Supabase SDK synchronizes local data with a PostgreSQL-backed cloud database, enabling seamless multi-device usage. Supabase Auth manages secure authentication and sessions, while Supabase Storage handles file attachments. Server-side logic such as recurring tasks, reminders, and data validation is implemented using Supabase Cloud Functions. Trigger.dev orchestrates cron-based jobs and automated workflows, ensuring reliable background execution without dedicated servers. The result is a fully serverless, cloud-native productivity platform.
