Verificación de HTTP/2

Comprueba si el sitio web es compatible con el protocolo HTTP/2.

Datos clave

Check HTTP/2 online: enter a site address and see which protocol the server negotiated, HTTP/2 or HTTP/1.1. Free, no sign-up. The site is tested after redirects; HTTP/3 support is not tested.

Precio: Gratis
Registro: No necesario
Procesamiento: On our server: it requests your site over HTTPS preferring HTTP/2 and checks which protocol was negotiated
Entrada: A site address (for example https://example.com)
Límites: 30 checks per minute per IP, no sign-up and no daily limit; up to 5 redirects
Resultado: The negotiated protocol (HTTP/1.1 or HTTP/2), an HTTPS flag, the response code, the final address after redirects and a verdict on whether HTTP/2 is supported

Verificación de HTTP/2

Comprueba si un sitio es compatible con HTTP/2. HTTP/2 acelera la carga mediante multiplexación y compresión de encabezados. Solo se prueba HTTP/2 (la solicitud se hace por HTTP/2 con negociación ALPN); HTTP/3 no se comprueba.

FAQ

Enter the site address and click Check. The tool sends an HTTPS request preferring HTTP/2 and shows the negotiated protocol. No sign-up is needed; the limit is 30 checks per minute.

Browsers use HTTP/2 only over HTTPS, so a certificate is needed to benefit. Our tool validates the certificate and gives no result if it fails.

No, only HTTP/1.x and HTTP/2. We do not test QUIC or the Alt-Svc header, so a site with HTTP/3 shows the protocol negotiated over TCP.

Possible causes: HTTP/2 was enabled on the wrong virtual host, a proxy in front of the server lacks HTTP/2, the site is opened over HTTP rather than HTTPS, or the configuration cache is not refreshed.

The protocol is not a direct ranking factor, but it reduces load time, which feeds into page speed measurements.

Desplaza la tabla hacia los lados

Dónde somos más débiles: no HTTP/3 check, no custom IP or port, and only the final protocol is shown without negotiation details.

Cuándo elegir PromoPilot: When you want to confirm quickly that HTTP/2 really works after enabling it on the server or CDN. For HTTP/3 and detailed TLS diagnostics other tools are needed.
