Hey PH! Im a solo dev who got tired of bookmarking 10 different tool sites for JSON formatting, regex testing, Base64 encoding, etc. So I built one page that does all of it — and made sure nothing gets sent to a server (everything runs in your browser).
Currently at 19 tools, all free, no signup. Would love feedback from fellow devs on what I should add next.
