Non-developer ships QR code design tool built with Claude Code after 150 commits
VibinVentricles · reddit · 2026-10-26
A print-industry Redditor with no dev background built Zest (zest.lemoncello.studio), a QR code designer that weaves logos into the data by pushing dots toward an image's light and dark areas using QR redundancy, verifying scannability dot-by-dot before download.
Features: six woven styles plus Classic, animated codes with per-frame scan checks (18 presets + custom GIF), re-pointable smart codes with routing rules, an InDesign plugin, and new Labs drops (round codes, full-bleed, rings).
Claude Code workflow takeaways:
- A CLAUDE.md with rules: confirm requests before building, phone screenshots are ground truth, one change per commit, never claim "deployed"
- A single verify script (build, JS syntax check, page loads with security headers at both widths, Worker security tests) that must pass before anything counts as done
- A short retrospective after every session — 27 so far — so the next session starts briefed
Started mid-August in browser chat, moved to Claude Code in late September, 150 commits since. Pricing: free to design, $4 one-time for 14 days of unlimited static downloads, Pro $12/mo, Business $30/mo.
