Why I Built This
As a developer constantly learning new technologies, I found myself keeping notes scattered across multiple places — Logseq, Notion, random text files. I wanted a single, beautiful, searchable reference I could access from anywhere.
So I built Free Code Notes: a Quartz-powered digital garden that converts my Logseq notes into a fast, searchable website — and made it free for everyone.
