SPDY (pronounced "speedy")[1] is a deprecated open-specification networking protocol that was developed primarily at Google for transporting web content.[1] SPDY manipulates HTTP traffic, with particular goals of reducing web page load latency and improving web security. SPDY achieves reduced latency through compression, multiplexing, and prioritization,[1] although this depends on a combination of network and website deployment conditions.[2][3][4] The name "SPDY" is a trademark[5] of Google and is not an acronym.[6]

Throughout the process, the core developers of SPDY have been involved in the development of HTTP/2, including both Mike Belshe and Roberto Peon. In February 2015, Google announced that following the recent final ratification of the HTTP/2 standard, support for SPDY would be deprecated, and that support for SPDY would be withdrawn.[7] Google removed SPDY support in Google Chrome 51. Mozilla removed it in Firefox 50.[8] Apple has deprecated the technology in macOS 10.14.4 and iOS 12.2.[9]
