Pocket Ledger is an opinionated envelope-budgeting app. It stays out of your way, runs on a single small server, and exports everything to plain CSV whenever you want to leave.

The idea

I wanted a budgeting app that felt like a plain text file but rendered like a good product. No ads, no bank integrations, no lock-in.

What I built

An Astro frontend with a small Hono API talking to SQLite on disk, plus a honest little import/export flow. Auth is passkeys only.

Outcome

Used by me, my partner, and a handful of friends. Still the fastest app on my phone.

Next project

A calm, keyboard-first admin panel for an indie analytics tool.
