13 Free SEO Tools I Built (No Signup, No Email)

I've been doing SEO for my own projects for a while now. And I kept getting annoyed at the same thing over and over.
Simple stuff costs money.

Why I made these

Honestly? I was scratching my own itch.

I have several side projects and I got tired of switching between 10 different tools just to do basic checks. So I built everything into one place.

Then I figured — why not make it public? Maybe others find it useful too.

No catch. No "free tier with limits". Just tools.
