You know that thing where you need to quickly decode a JWT, or convert a timezone, or check a color's contrast ratio — and you end up on some sketchy ad-riddled site that probably logs your data? Yeah, I got tired of that. So I built ToolPlex (toolplex.dev) — a free collection of 60+ browser tools for the stuff I reach for all the time. The whole thing runs locally in your browser, so nothing is ever sent to a server. No account required, no ads, no nonsense. Some highlights: Dev tools: JSON formatter/diff, JWT decoder, regex tester, Base64, hash generator, CRON explainer Design: color converter, contrast checker, gradient builder, palette generator Calculators: loan, mortgage, compound interest, ROI, BMI Images: resize, compress, convert Date & time: timezone converter, Unix timestamp, business days, Pomodoro timer ...and a bunch more I'm constantly adding new tools based on what people actually search for. Would love to hear what you'd find useful — happy to add requests!
