Know exactly what a production engineer would flag on your site — before it costs you a customer.
TechDoctor reads your live site the way a senior engineer would — performance, security, TLS, accessibility and production-readiness — then shows you the top risks in plain language, ranked by what they actually cost you. You see everything free, up front, with no signup.
Every scan runs Google PageSpeed Insights — Google's own Lighthouse audit, on Google's neutral bench — right alongside our deeper read. Two independent verdicts, not just ours.
How it works
Three steps, nothing to install — a real diagnosis you can act on the same day.
Paste your URL
Just the address of your live site. No access, no code, no signup — TechDoctor reads only what's already public.
We run two audits
Google PageSpeed Insights — the Lighthouse engine, on Google's own neutral bench — scores performance, accessibility, SEO and best practices. In parallel, our own engine checks what Google can't see: security headers, TLS, exposed paths, outdated libraries and real-browser Core Web Vitals.
Get ranked, plain-English fixes
One 0–100 score with a letter grade, your risks ordered by what they cost you, and an honest line on what only a human review can catch.
How we measure — and why you can trust the number
One page can score 55 on a tired laptop and 95 on a fresh one — Lighthouse moves with the machine that runs it. Here's why our performance number doesn't, and where our own read sees what Google can't.
Run through PageSpeed Insights
Your performance, accessibility, SEO and best-practices scores come straight from Google PageSpeed Insights — the same Lighthouse engine behind Google Search's page-experience signals. It's Google's number, shown unedited and linked back to Google.
A bench nobody can tilt
Google runs that audit on its own neutral servers — not your machine, not ours. The score reflects your site, not whoever happened to test it on a busy day. Host-independent, repeatable, and impossible to quietly tune in anyone's favour.
Everything Google can't see
Lighthouse never inspects your security headers, TLS setup, exposed paths or outdated libraries. Our own engine runs right alongside it — plus real-browser Core Web Vitals — so you get the full production picture, not just the Google slice.
What you walk away with
See it in action
Watch a real scan run start to finish — no click to play. Both audits fire, the progress fills, the score counts up, and each category grade reveals, exactly the way it does on your own site.
A live demo of the scanner UI — your real report shows the same score ring, Google Lighthouse grades and ranked fixes.
Built for every kind of site
The same scan reads a storefront, a SaaS app and a marketing site — and speaks to what each one actually stands to lose.
Every second is revenue
Slow Core Web Vitals and layout shift quietly bleed conversions on mobile. TechDoctor puts a number on the checkout experience Google actually measures.
Trust starts at the front door
Missing security headers, a weak TLS setup or an exposed path signals risk to the exact buyers doing due diligence. See what they'd see first.
Proof you can hand a client
An independent Google Lighthouse score plus a ranked fix list makes a credible, unarguable case — and a clear before/after you can show.

Real signals only — no fabricated grades. A clean app gets a clean score.
The headline number, straight from Google's own Lighthouse engine on Google's neutral bench — so it reflects your site, not our hardware or the moment you tested. This is the score that counts. Our deeper diagnostic sits below it.
These scores come from Google PageSpeed Insights — the same Lighthouse engine behind Google Search's page-experience signals, run on Google's own neutral servers, not a machine we or you control. That's the point: the identical page can score in the 50s on a busy laptop and in the 90s on an idle one, because Lighthouse moves with the hardware running it. Anchoring to Google's bench means this number reflects your site — not our hardware, not the moment you tested — and it can't be tuned to flatter anyone.
Beyond Google's four scores: security headers, TLS, exposed paths and outdated libraries, folded into one grade. It complements the official verdict above — it doesn't replace it.
TechDoctor runs page-quality, security, TLS, and accessibility checks on every scan — no setup, no opt-in. Real signals only; a check that genuinely can't complete is shown honestly, never faked.
We load your page in a real mobile browser and capture the signals Lighthouse never reports: JavaScript errors on load, how many requests go to third parties, and the real bytes transferred. The graded performance number is Google's, above.
Beyond the aggregate scores: the production-readiness signals that need TechDoctor's deeper read.
What a street-view scan can't see
Even with the aggregate plus the deeper read, an outside scan has a hard limit — this is exactly where an automated scan stops and a human review begins. These five need eyes on your code and your data:
