HTTP/3 Ready Products
LiteSpeed was the first to introduce production-grade HTTP/3 web server support. But we didn't stop there. As the new protocol continues to be defined, we are there at every step, keeping our implementation current and cutting-edge. All of our server products across the board feature HTTP/3 support.
Open Source HTTP/3 Library
We believe in doing our part to advance Internet technologies, and with that aim in mind, our LSQUIC project is Open Source, and available on GitHub.
The LSQUIC Library is a fully functional, actively maintained QUIC and HTTP/3 implementation in the C programming language, allowing you to incorporate the same QUIC functionality used in LiteSpeed servers into your own projects.
QUIC.cloud CDN
QUIC.cloud CDN, the content delivery network built on a LiteSpeed stack, was designed specifically to take advantage of the benefits of HTTP/3 and QUIC. As you'd expect, QUIC.cloud serves content via HTTP/3 to visitors, but it also can communicate with a site's backend via HTTP/3 and QUIC, making for a complete HTTP/3-powered connection.
HTTP/3 Verification Service
You can test your own site, or any site on the Internet with the free HTTP/3 Check tool. Enter a URL, and HTTP/3 Check will tell you whether QUIC or HTTP/3 are supported by that site. Detailed connection information, including HTTP header and QLOG output are provided as well.
Please check out our video tutorial on how to check if your website is using QUIC or HTTP/3 if needed.
