I Built 44 Free Developer Tools — Here's What I Learned

TL;DR: I built 44 free developer tools at karangoyal.cc/tools — Shopify Liquid formatter, theme detector, JSON formatter, regex tester, image optimizer, and more. All free, no sign-up, client-side processing. Here's the full list and what I learned. I'm a Shopify developer (Top Rated Plus on Upwork, $300K+ earned), and over the past year I've been building free developer tools on my personal site. Not as a business — just to scratch my own itches and help other developers.

Finds performance issues (nested loops, N+1 queries), security problems (missing escape filters), and scores your code 0-100 with actionable fixes. Shopify Theme Detector Enter
