FastestChecker
20 free, no-signup web tools every developer needs
FastestChecker is a free toolkit of 20+ browser-based utilities for developers: IP checker, JWT decoder, email validator, password generator, speed test, and more. No signup, no paywalls, most tools run entirely client-side.
Hey Product Hunt!
I built FastestChecker because I was tired of having 15 browser tabs
open just to do routine dev checks — what's my IP, is this JWT valid,
will this email actually bounce — each one behind a different sign-up
wall or ad-gated redirect.
FastestChecker puts 20+ of these tools in one place, free, with no
account required. A few I use almost daily:
IP Checker — see your current public IPv4/IPv6 in one click
JWT Decoder — inspect a token's header/payload without pasting it
into a random site you don't trust
Email Validator — syntax + MX record checks before you trust a
signup
Password Generator — configurable, generated entirely client-side
Speed Test, PageSpeed Checker, Domain Age Checker, and more
Most of these run client-side in your browser — nothing gets sent to
a server just to check your own IP or generate a password.
Would love feedback on what's missing. What's the one "quick check"
tool you always end up hunting for online? Happy to add it.
Thanks for checking it out!
