Building Forgly in public — 20+ free dev tools, no signup

Hi IH! I'm Cheng, a solo dev. For the past few months I've been building Forgly (https://forgly.dev) — a set of 20+ free tools developers reach for daily: JSON formatter, JWT decoder, cron builder, regex tester, UUID generator, and a few AI helpers. No signup, no ads, everything runs in the browser. I got tired of cluttered, ad-heavy tool sites, so I made a clean fast one. It's live now and I'm sharing the journey here — revenue, traffic, what works and what doesn't. Would love any honest feedback on the tools or the landing page. What dev tool do you wish existed but doesn't?
