SEO tools we built for our own work
No signup, no limits, no email gate. These are the small checks we kept doing by hand on client sites until it made sense to build them properly.
- hreflang.check
$check https://yoursite.com/uk/
✓12 hreflang tags found
!missing x-default
✕en_US — underscore, not a valid code
Hreflang Checker & Generator
Read the hreflang tags off any live page — bad codes, missing x-default, missing self-reference — or generate a correct set for your language versions.

What should we build next?
Every tool here started as a check we kept doing by hand on real sites. If there is a small SEO job you repeat manually, tell us — the useful ones get built.

Beyond the free checks
Need the fix, not just the finding?
The tools show you what is broken. If you want it fixed properly — hreflang, canonicals, indexation, the lot — send us the site and the problem.
