Stop Sending Your JWTs and Private IP Ranges to Random Servers: Why We Need Client-Side Developer Tools

dev.to Security2026-10-28 07:100 views

Whenever you paste a bearer token into a random online debugger, do you know where those payload bytes are sent?

To guarantee data security for infrastructure and backend engineers, I created MicroTools (https://micro-tools.xyz):

✅ 100% Client-Side execution (runs inside your browser sandbox)
✅ Zero server roundtrips or backend logging
✅ 18 free utilities: IPv4 CIDR Calculator, JWT Decoder, Cron Builder, Port Directory, and BER-TLV Parser.

Give it a try and bookmark it for your daily workflow: https://micro-tools.xyz
