Tools
Free SEO & GEO tools.
Practical tools we built for our own consulting work — now free for everyone. Server-side fetching, no signup, no upsell wall. Built by the same engineers who ship our client SEO programs.
How a Contingo tool works
All fetching happens server-side. Your browser never touches the target URL — so CORS, mixed-content and private-IP blocks are enforced for you.

Under the hood
Engineered like the rest of our work.
Every tool here runs on the same edge stack we ship to clients — TanStack Start server functions on a Cloudflare-style worker runtime, with strict input validation, SSRF protection, and a 1MB cap on remote responses. No third-party SaaS in the middle.
Server-side fetching
Your browser never touches the target URL. The audit and meta-fetch run on our edge — so CORS doesn't lie to you and your IP isn't exposed.
SSRF-hardened
Every redirect hop is re-validated against private-IP and metadata-host blocklists. We refuse http://localhost, 169.254.x and friends.
Honest scoring
We weight what actually moves rankings — title, indexability, schema, internal links — not vanity metrics that pad a 100/100 number.
Copy-paste output
Schema and meta-tag snippets are deterministic, minified-clean, and validated before they're offered for copy. Drop them straight in <head>.
