I built an AI-first open-source budgeting app. It runs on top of Claude Code. Here's how it works.

A baby on the way, moving to a different country, a new job, and buying a house, all in the last 12 months. That's why I wanted to start budgeting properly. So I looked at what was available. YNAB, Copilot, Monarch... all these are subscription-gated and cloud-dependent. None have a good free tier or great AI features.
