Check uptime, SSL, PageSpeed, security headers, SEO and WordPress health in one report.
GTmetrix checks speed. SiteBrief checks everything.
8 checks run in parallel in under 40 seconds
Checks if your site is online right now, measures server response time in milliseconds, and verifies the HTTP status code returned.
Know instantly if your site is down or slow.
Validates your SSL certificate, checks whether HTTPS is properly configured, and shows how many days until your cert expires.
Catch expiring certs before they break your site.
Runs Google Lighthouse on both desktop and mobile, returning a 0–100 performance score based on real Core Web Vitals data.
Same tool Google uses to rank your pages.
Checks for critical HTTP security headers: Content-Security-Policy, X-Frame-Options, HSTS, X-Content-Type-Options and more. Assigns a letter grade A–F.
Missing headers are the #1 low-effort security fix.
Audits meta title, meta description, H1 tag, canonical URL, robots.txt, sitemap, Open Graph tags, and structured data presence.
7 checks that cover 80% of on-page SEO issues.
Detects if the site runs WordPress, identifies the version, and flags whether the version is exposed publicly (a security risk).
WordPress powers 43% of the web — we speak its language.
Checks your domain against major spam and malware blacklists. A blacklisted domain causes emails to bounce and browser warnings.
Find out before your clients do.
Looks up your domain registration and shows how many days until it expires. Domains that expire cause complete site outages.
One check that takes 30 seconds could save your business.
Three steps, no account needed
Paste any website URL. We auto-add https:// if needed. Works with any publicly accessible site.

A unique URL is generated for your report. Share it with clients, add it to proposals, or bookmark it for later.

Yes, completely free. No signup, no credit card, no email required. Run as many audits as you want. Each audit creates a unique shareable URL you can send to clients.
We use the official Google PageSpeed Insights API, the same tool that powers search.google.com/search-console. The score is identical to what you'd get from Google directly.
GTmetrix and Pingdom focus only on speed. SiteBrief checks 8 different areas: uptime, SSL, PageSpeed (mobile + desktop), security headers, SEO, WordPress health, domain expiry, and blacklists — in a single report.
Yes. Every audit generates a unique URL like sitebrief.net/audit/results/xyz that anyone can open — no login needed. It's perfect for including in client proposals or maintenance reports.
Usually 20–40 seconds. All checks run in parallel so it's as fast as the slowest individual check (typically PageSpeed).
