Weak passwords are still one of the biggest security risks.
As a small experiment, I built a free password strength checker that runs entirely in the browser.
What makes it different:
No passwords are stored or sent to any server
Uses entropy-based checks, not simple rules
Works offline once loaded
Mobile and desktop friendly
I noticed most tools either feel outdated or push signups.
My goal was to keep it simple, fast, and privacy-first.

I am also adding a password generator with customizable length and character sets.
If you are a developer or student, feedback is welcome.
Happy to improve it further.
