Most free SEO checkers give shallow, generic results

Most "free SEO audit" tools online fall into two camps: a generic checklist that isn't actually checking your page at all, or a proper SaaS tool with a free tier so limited it's barely usable. We wanted something that gives a real, useful answer the moment someone uses it — an actual check of their actual page, not a template.
A self-serve tool: enter a URL, and the server fetches and audits that actual site live — title and description length, missing alt text, structured data, sitemap and robots.txt presence, mobile viewport — plus a real Google PageSpeed performance score, not an estimate. Because this means fetching a URL a visitor controls, it's built with the same security discipline as anything else on the site that touches untrusted input: private and internal addresses are blocked before any fetch happens, protocols are restricted to HTTP/HTTPS only, and every redirect hop is re-validated.
Five steps, from URL to report.
Any public website
Private addresses blocked before fetching
Same audit we run on our own site
Real Google performance score
Shown on-page, no waiting
We ran the tool against kasatech.in itself before pointing anyone else at it — the same "test it on ourselves first" discipline behind every build here. It now scores 100/100 on its own audit.
A useful free tool, built with the same care as anything we'd ship for a client.
