// FREE SPEED & HOSTING TOOLKIT
Every host says they're fast.
We check.
Core Web Vitals, server response time, DNS, SSL, uptime — measured with real requests and diagnosed in plain English. The tools are free and results aren't stored.

// THE TOOLKIT
Six instruments. One job: find what's slow.
// METHODOLOGY
How every test works
01
Measured, not estimated
Every check is a real request — timed fetches, TLS handshakes, DNS queries against live resolvers. Results are labeled with the exact vantage point they were measured from.
02
Graded against real thresholds
Metrics are banded using Google's published Core Web Vitals cut-offs and documented constants — the same thresholds for every site, every run.
03
Diagnosed in plain English
Numbers alone don't fix anything. Each result names the worst offender, explains what causes it, and says what actually moves it.
Independent by design. Measurements are never altered by commissions. Where a result points at products, performance claims cite an external benchmark and affiliate links are marked. How this site works →
// HOSTING LEADERBOARD
The hosts we track
Server response time (TTFB) is the part of page speed your hosting controls — and it's measurable. We rank hosts only when cited, measured data backs it — never on marketing copy.

// QUESTIONS
Fair questions
Is this actually free?+
Yes. Every tool runs without signup, payment, or stored data. Run as many tests as you like.
How does this site make money?+
Affiliate links. When a result points at hosting or services, some links are affiliate links — marked where they appear, with commissions that never change a measurement or an ordering. The full policy is on the privacy & disclosure page.
How accurate are the results?+
Speed tests use the Google PageSpeed Insights engine (lab runs plus real-visitor field data where it exists). Server-side probes — TTFB, uptime, latency, DNS, SSL — are real timed requests from this site's server, labeled with their vantage point. One region today; multi-region is planned.
What's a good TTFB?+
Under roughly 300ms is good; over roughly 800ms is slow. Dynamic sites naturally sit between the two. The “what is TTFB” guide covers the details.
What can I test?+
Any public website you own or are authorized to check — the probes are ordinary HTTP, DNS, and TLS requests, the same things a browser does.
// GUIDES
Understand the numbers
- What is TTFB (Time to First Byte)?TTFB measures how long your server takes to start responding to a request. Here's what it includes, what counts as a good TTFB, and why it matters.
- How to fix a slow TTFBA slow Time to First Byte is a server-side problem. These are the fixes that actually move it: caching, CDNs, database work, and hosting.
- What is a good Core Web Vitals score?Core Web Vitals are Google's three user-experience metrics: LCP, CLS, and INP. Here are the thresholds that count as good, and what each metric actually measures.
- How to check DNS propagationAfter changing a DNS record, resolvers around the world update at different times. Here's how propagation works, how long it takes, and how to check it.
- Why is my website down?A site can be down for everyone or just for you. Here's how to tell the difference, the most common causes, and what to check in what order.
- SSL certificate expired: what happens and how to fix itWhen an SSL certificate expires, browsers block the site with a full-page warning. Here's why certificates expire, how to fix it, and how to prevent it.
- What is website latency? (and what counts as good)Latency is the round-trip time between a visitor and a server — distinct from bandwidth. Here's what adds to it, typical values, and how to reduce it.
