AI Analysis

●●SolidCozySolve My Problem

SQLite WASM in browser with Cloudflare D1 sync beats typical SaaS expense trackers.

Strengths

•wa-sqlite with IndexedDB persistence means data stays local until you opt into sync
•Bidirectional Cloudflare D1 sync via Workers is genuinely serverless-edge architecture
•No account required to start tracking — privacy by default, not forced

Weaknesses

•Expense tracking is crowded (YNAB, Mint, Copilot) — sync approach is the only differentiator
•PWA-only means no native mobile app, limited push notification capabilities

Post Description

I built pancakemaker for myself as a dead-simple personal expense tracker that works fully offline and syncs when you're back online.

The core idea: SQLite runs in the browser via WASM as the local store, and Cloudflare D1 handles cloud sync — no traditional backend needed.

The whole stack is serverless-edge (Cloudflare Workers + D1), so it's cheap to run and fast to deploy. I wanted something I'd actually use daily without worrying about yet another SaaS subscription.

Would love feedback on the sync approach and whether the WASM-first architecture holds up in practice.
