My Swiss Army Knife
for technical SEO.
I built this toolkit to stop writing throwaway scripts for every little problem. It handles the messy edge cases the big tools ignore. I also add stuff I think is cool.
The ones that get the most use
Filter by category or browse the lot

Built for the gaps the big tools leave
They handle scale
I use these on sites with thousands of URLs and massive exports. They don't choke.
Fill the gaps
The stuff Screaming Frog and Ahrefs don't do. Jobs that used to mean opening Python or asking a dev.
Your data isn't kept
No tracking, no selling your queries. Files are processed then deleted.
If something's missing, tell me.
Most of these tools exist because someone asked. If you have a recurring SEO chore that needs better tooling, send a quick email.
