16 developer tools in one fast, ad-free tab: RegexLab, JSONCraft (TypeScript/Zod/CSV export), CronBuilder, JWT Decoder, APITester, ColorSystemPro, SQL Formatter, YAML⇄JSON, and more. The privacy-sensitive ones (hashing, JWT) run entirely in your browser — nothing hits a server. Start free, no account. Instead of another subscription, it's a one-time $79 lifetime, with first-class support for local payment methods so devs outside the US card system aren't locked out.

Hey Product Hunt 👋 I'm Ashik, a solo dev from Bangladesh.
I got tired of googling "json formatter," then "cron generator," then "jwt decoder" five times a day — a different ad-heavy site for each, half of them wanting an account.
So I built DevTools: 16 of those utilities in one fast, ad-free tab. JSONCraft even spits out TypeScript interfaces and Zod schemas; the hashing and JWT tools run entirely in your browser (nothing leaves your machine).
Two things I care about: it's genuinely useful on the free tier (no card), and instead of another subscription it's a one-time $79 lifetime — with local payment methods so devs outside the US card system aren't locked out.
I'm here all day. What's the small dev task you google most often? I'll tell you if there's already a tool for it (or add one).
