Home / Free Website Grader
Grade any site.
In seconds.
Drop a URL and The Grader walks six lenses — speed, accessibility, SEO, security, trust and reputation — then hands back a measured score with the exact fixes that move it. We don't guess. We grade.
Six lenses
● Measured — a live reading ○ Estimated — a confidence-aware read until live scanning reaches this lens
Sample evaluation — this demonstrates how a Grader report reads; live scanning of your URL is rolling out.
The Deep Report

The grade is free. The Deep Report hands you the exact fixes — and the $50 becomes a $50 credit toward your build with Houtos Labs.
Watch one happen.
This is how a Grader evaluation moves — scan the live site, resolve a score, then hand back the fixes that matter. Scroll to step through it; on a phone it plays on its own. A sample walkthrough, not a live scan of your URL.

Sample walkthrough · full live measurement (Lighthouse + axe-core) is rolling out; this shows how a Grader evaluation reads, not a live scan of the URL you enter.
Scan. Score. Synthesize. Recommend.
Four steps, every time, in the same order — so the result is repeatable and the fixes are ranked by impact, not by hunch.
Scan
We read your live, public pages and pull observable signals — load behavior, structure, accessibility markers, security headers. Nothing is copied or stored.
Score
A weighted, confidence-aware model turns signals into grades across 5 axes and 26 metrics — measured and estimated kept apart.
Synthesize
Grades become a plain-language read of strengths, risks and trade-offs — one story, not 26 disconnected numbers.
Recommend
A prioritized fix list — biggest impact first, with the score lift each change is likely to deliver.
The grader you can run today is a careful, confidence-aware sample. Full live measurement — real performance and accessibility scans via Lighthouse and axe-core — is rolling out, and any score we estimate is labeled Estimated rather than dressed up as a fact — each label upgrades to Measured automatically as live scanning reaches that lens.
A grade you could defend in a board meeting.
Curious what the output actually looks like? Walk through a full sample report — the overall grade, every category broken out, the measured-versus-estimated labels, and the exact fix list, in the same layout you will get for your own site.
Website grader FAQ.
What is a website grader?+
A website grader checks a site against a fixed set of quality signals and turns the results into one comparable score. Instead of an opinion that a page “feels slow,” you get a measured grade across performance, accessibility, SEO, security, trust and reputation — plus a ranked list of what to fix first. Because The Grader scores every site the same way, two pages compare like-for-like.
Is the website grader free?+
Yes. The free audit gives you an overall score, the six category grades, and the top fixes in plain language — no account required. Paid tiers add deeper synthesis, more per-category detail, white-label reports and lead-qualification, but the core grade stays free to run.
What does it check?+
Six lenses: Speed & Performance, Accessibility (ADA/WCAG), Findability (SEO & AEO), Security & Privacy, Trust & Compliance, and Reputation — 26 signals across 5 axes, resolved into one weighted score. The full rubric lives on the how we grade page.
How accurate is the score?+
We are honest about this. Full live measurement is rolling out. Until a category is fully live for your site, its score is a confidence-aware estimate from observable signals, clearly labeled Estimated and kept separate from measured readings.
Do you store my site?+
No. The Grader reads your public pages to score them; it does not copy, archive or republish your site. Lead capture is dormant by default, so running a grade signs you up for nothing.
How is it different from PageSpeed Insights?+
PageSpeed measures one thing well — speed and Core Web Vitals. The Grader is broader: speed is one of six lenses. We also grade accessibility, SEO/AEO, security, trust and reputation, then combine them into one defensible score with a prioritized, plain-language fix list.
