MonitorMyHost is a website monitoring platform and free toolkit for developers, DevOps teams and SEO professionals. Monitor website uptime, run a free TTFB test, generate Lighthouse and Core Web Vitals reports, and use our DNS lookup, redirect checker and WHOIS lookup to find and fix problems before they hurt your traffic and rankings.
A website that is down, slow or misconfigured loses visitors, sales and search rankings, often before anyone on the team notices. Most teams end up juggling one tool for an uptime check, another for a website speed test, and a third for a DNS lookup.
MonitorMyHost brings website uptime monitoring, server response time (TTFB) testing, Google Lighthouse analysis and DNS and domain diagnostics into one agentless platform. Everything runs from external probes, so you see your site the way real users and search engine crawlers do.
Independent probes in tier-1 data centers check your site at the same time from several continents. This confirms real outages, filters out false alarms from a single bad route, and shows how your site responds to visitors in each region, without browser cache getting in the way.
Catch server downtime, TLS handshake failures, timeouts and 5xx errors fast. Get notified by email, Slack, PagerDuty or custom webhook so your team can respond before customers or search engines notice.
Lighthouse audits run on mobile and desktop profiles and report Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), Total Blocking Time (TBT), SEO and accessibility issues, so you know exactly what to fix to improve page speed and rankings.
Query authoritative nameservers for A, AAAA, MX, CNAME, TXT, NS and SOA records, trace HTTP redirect chains, and check WHOIS data. Everything you need to troubleshoot DNS propagation, email delivery and migration issues.
Use our free online tools to test TTFB, analyze page speed, look up DNS records, trace redirects and check domain WHOIS data.
Time to First Byte checker
Run a free TTFB test from multiple global locations. Measure DNS, TCP, TLS and server response time to find slow origins and weak CDN edges.
Website speed test
Get a free Google Lighthouse report for mobile and desktop: LCP, CLS, TBT, SEO, accessibility and best-practice scores for any URL.
DNS checker
Free DNS record lookup for A, AAAA, MX, CNAME, TXT, NS and SOA records. Verify propagation, email setup and nameserver health.
HTTP redirect trace
Trace 301, 302 and 307 redirect chains hop by hop. Fix redirect loops and slow chains that waste crawl budget and SEO link equity.
Domain WHOIS & expiry
Look up domain registrar, creation date, expiry date and nameservers to avoid surprise domain expiration.
Monitor APIs, staging and production, and get alerted the moment a deploy breaks something.
Audit TTFB, Core Web Vitals, redirects and DNS for every client site from one place.
Protect revenue by catching downtime and slow pages before they cost you checkouts and signups.
Keep client websites online and prove uptime with clear monitoring history.
Answers about free uptime monitoring, TTFB testing, Core Web Vitals, DNS lookup and website performance.
MonitorMyHost is a website uptime monitoring and server performance platform with free online tools. It combines uptime checks, multi-location TTFB testing, Google Lighthouse Core Web Vitals reports, DNS lookup, redirect checking and WHOIS lookup, so you can find and fix website downtime and speed problems quickly.
Yes. You can create a free account and start monitoring your website uptime, response time and availability. The diagnostic tools (TTFB test, Lighthouse report, DNS lookup, redirect checker and WHOIS lookup) are free to use without signup or a credit card.
MonitorMyHost covers the same core need as tools like UptimeRobot: tracking whether your website is up and alerting you when it is not. It adds multi-location TTFB testing, Lighthouse and Core Web Vitals reports, DNS lookup and redirect tracing in the same platform, which makes it useful if you want uptime and performance analysis together.
Time to First Byte (TTFB) measures how long a browser waits to receive the first byte of a response after requesting a page. Enter your URL into our free TTFB test to see timing from multiple locations, including DNS lookup, connection, TLS and server processing time. As a rule of thumb, Google considers a TTFB under about 800 ms good.
TTFB is not a Core Web Vital itself, but a slow server response delays everything after it, including Largest Contentful Paint (LCP), which is a Core Web Vital and a Google page experience signal. Lowering TTFB with better hosting, caching and a CDN gives crawlers and visitors faster access to your content.
A single-location checker can miss regional outages and often hits a cached CDN node. MonitorMyHost tests from probes across North America, Europe and Asia-Pacific, so you see real availability and latency for visitors in different regions and can confirm an outage before alerting you.
No. MonitorMyHost works externally, like a real visitor. There is nothing to install, no root access required, and no performance overhead on your server.
Use the free DNS lookup tool: enter your domain and choose a record type such as A, AAAA, MX, CNAME, TXT, NS or SOA. It helps you verify DNS changes, email (MX, SPF, DKIM) records and nameserver configuration after a migration.
Start with a TTFB test to see whether the server is slow, then run a Lighthouse report to find front-end issues such as large images, render-blocking scripts and layout shifts. Check the redirect chain and DNS timing too, since both add delay before the page starts loading.
Add your URL as a monitor, choose a check interval, and connect alert channels such as email, Slack, PagerDuty or a webhook. You are notified when the site goes down and again when it recovers.
