S01 Snapshots
Kaban, as it ships.
Real captures of the build: the desktop view, the phone, and the whole page.
C01 What it is
The build, in passes.
Kaban is a Next.js web app and PWA plus an Expo iOS and Android app for private accounts, purpose wallets, goals, splits, groceries, planning and activity. Postgres in Supabase is the source of truth; the web app keeps a per-user IndexedDB cache and outbox, and the mobile build uses an encrypted SQLCipher store with a durable outbox.
- Accounts, purpose wallets, goals, splits, groceries and planning
- Offline layer: IndexedDB outbox and service worker on the web, SQLCipher on mobile
- Supabase Auth, Row-Level Security and pgTAP database tests
- Tala, an AI preview that asks for explicit AI-data consent first
- Expo development-client build in progress
