HTTP/2 Checker

Our HTTP/2 Checker determines whether a website has implemented the HTTP/2 protocol, which offers significant performance benefits over the older HTTP/1.1 standard. HTTP/2 improves page load speeds through features like multiplexing (allowing multiple requests over a single connection), header compression, and server push capabilities. This diagnostic tool helps web developers, performance engineers, and site administrators verify HTTP/2 deployment and troubleshoot connection issues. Performance-conscious website owners use it to confirm their hosting environment properly supports this modern protocol, as HTTP/2 can substantially reduce latency and improve user experience, especially on resource-heavy websites. The checker performs a specialized connection test that accurately determines protocol support regardless of intermediate proxies. Whether you're optimizing your own website, researching competitor implementations, or evaluating hosting providers based on modern protocol support, this tool provides immediate verification of HTTP/2 capability without requiring technical server access or specialized software.
