Why I built 20+ privacy-first web tools (and what's next)

Hey Product Hunt community! 👋

I'm a solo indie dev. I got tired of simple web tools forcing me to sign up, verify my email, and tracking my data just to check a BMI or generate a password.

So I built Lihayo Tools: 20+ free utilities that run 100% locally in your browser. No servers, no tracking, no signup.

I'm officially launching on Product Hunt this Tuesday (Oct 27). I'd love to hear your thoughts: what is the one online tool you wish existed that didn't require a signup?

Let me know below! I'll be adding the best ideas. 👇
