Compare response times across providers
The CDN Performance Checker helps you compare the Time to First Byte (TTFB) performance of popular CDN providers using data collected from real-world speed tests. By analyzing response times across different regions, cache statuses, and time periods, you can better understand how CDN performance varies between providers and geographic locations.
This tool is useful for developers, website owners, agencies, and infrastructure teams evaluating CDN options. Since CDN response times can directly affect page load speed and user experience, comparing providers based on measured performance data can help you make more informed infrastructure decisions.

Make better CDN selection decisions
Choosing a CDN is about more than pricing and features. Network coverage, caching efficiency, routing, and edge server performance all influence how quickly content reaches visitors. The CDN Performance Checker provides an easy way to benchmark providers and identify which CDNs deliver lower TTFB in specific regions or under different cache conditions.
Whether you're migrating to a new CDN, comparing alternatives, or researching performance trends, this tool offers a practical overview of how major CDN providers perform over time. Regional filtering and historical data views make it easier to evaluate providers based on the locations that matter most to your audience, helping you select a CDN that aligns with your website's performance goals.
