HTTP/3 is the third major version of the <a href="../Hypertext_Transfer_Protocol" class="mw-redirect" title="Hypertext Transfer Protocol">Hypertext Transfer Protocol</a> used to exchange information on the <a href="../World_Wide_Web" title="World Wide Web">World Wide Web</a>, complementing the widely deployed <a href="../HTTP/1.1" class="mw-redirect" title="HTTP/1.1">HTTP/1.1</a> and <a href="../HTTP/2" title="HTTP/2">HTTP/2</a>. Unlike previous versions which relied on the well-established <a href="../Transmission_Control_Protocol" title="Transmission Control Protocol">TCP</a> (published in 1974),<a href="#cite_note-rfc675-2">[2]</a> HTTP/3 uses <a href="../QUIC" title="QUIC">QUIC</a> (officially introduced in 2021),<a href="#cite_note-rfc9000-3">[3]</a> a <a href="../Multiplexing" title="Multiplexing">multiplexed</a> transport protocol built on <a href="../User_Datagram_Protocol" title="User Datagram Protocol">UDP</a>.<a href="#cite_note-4">[4]</a>

HTTP/3 uses similar semantics compared to earlier revisions of the protocol, including the same <a href="../HTTP#Request_methods" title="HTTP">request methods</a>, <a href="../HTTP#Response_status_codes" title="HTTP">status codes</a>, and <a href="../List_of_HTTP_header_fields" title="List of HTTP header fields">message fields</a>, but encodes them and maintains session state differently. However, partially due to the protocol's adoption of QUIC, HTTP/3 has lower latency and loads more quickly in real-world usage when compared with previous versions: in some cases over four times as fast than with HTTP/1.1 (which, for many websites, is the only HTTP version deployed).<a href="#cite_note-5">[5]</a><a href="#cite_note-6">[6]</a>

As of September 2024, HTTP/3 is supported by more than 95% of major web browsers in use<a href="#cite_note-canIuse-7">[7]</a> and 34% of the top 10 million websites.<a href="#cite_note-W3Techs-8">[8]</a> It has been supported by <a href="../Chromium_(web_browser)" title="Chromium (web browser)">Chromium</a> (and derived projects including <a href="../Google_Chrome" title="Google Chrome">Google Chrome</a>, <a href="../Microsoft_Edge" title="Microsoft Edge">Microsoft Edge</a>, <a href="../Samsung_Internet" title="Samsung Internet">Samsung Internet</a>, and <a href="../Opera_(web_browser)" title="Opera (web browser)">Opera</a>)<a href="#cite_note-Enabling_QUIC_in_tip-of-tree-9">[9]</a> since April 2020 and by <a href="../Mozilla_Firefox" class="mw-redirect" title="Mozilla Firefox">Mozilla Firefox</a> since May 2021.<a href="#cite_note-canIuse-7">[7]</a><a href="#cite_note-:2-10">[10]</a> <a href="../Safari_(web_browser)" title="Safari (web browser)">Safari</a> 14 implemented the protocol but it remains disabled by default.<a href="#cite_note-safari14-11">[11]</a>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

HTTP/3 originates from an <a href="../Internet_Draft" title="Internet Draft">Internet Draft</a> adopted by the QUIC working group. The original proposal was named "HTTP/2 Semantics Using The QUIC Transport Protocol",<a href="#cite_note-12">[12]</a> and later renamed "Hypertext Transfer Protocol (HTTP) over QUIC".<a href="#cite_note-:0-13">[13]</a>

On 28 October 2018 in a mailing list discussion, Mark Nottingham, Chair of the <a href="../Internet_Engineering_Task_Force" title="Internet Engineering Task Force">IETF</a> HTTP and QUIC Working Groups, proposed renaming HTTP-over-QUIC to HTTP/3, to "clearly identify it as another binding of HTTP semantics to the wire protocol [...] so people understand its separation from QUIC".<a href="#cite_note-14">[14]</a> Nottingham's proposal was accepted by fellow IETF members a few days later. The HTTP working group was chartered to assist the QUIC working group during the design of HTTP/3, then assume responsibility for maintenance after publication.<a href="#cite_note-15">[15]</a>

Support for HTTP/3 was added to <a href="../Google_Chrome" title="Google Chrome">Chrome</a> (Canary build) in September 2019 and then eventually reached stable builds, but was disabled by a feature flag. It was enabled by default in April 2020.<a href="#cite_note-Enabling_QUIC_in_tip-of-tree-9">[9]</a> Firefox added support for HTTP/3 in November 2019 through a feature flag<a href="#cite_note-canIuse-7">[7]</a><a href="#cite_note-16">[16]</a><a href="#cite_note-17">[17]</a> and started enabling it by default in April 2021 in Firefox 88.<a href="#cite_note-canIuse-7">[7]</a><a href="#cite_note-:2-10">[10]</a> Experimental support for HTTP/3 was added to Safari Technology Preview on April 8, 2020<a href="#cite_note-18">[18]</a> and was included with Safari 14 that ships with <a href="../IOS_14" title="IOS 14">iOS 14</a> and <a href="../MacOS_11" class="mw-redirect" title="MacOS 11">macOS 11</a>,<a href="#cite_note-safari14-11">[11]</a><a href="#cite_note-19">[19]</a> but it's still disabled by default as of Safari 16, on both macOS and iOS.

On 6 June 2022, <a href="../IETF" class="mw-redirect" title="IETF">IETF</a> published HTTP/3 as a <a href="../Proposed_Standard" class="mw-redirect" title="Proposed Standard">Proposed Standard</a> in <a href="../RFC_(identifier)" class="mw-redirect" title="RFC (identifier)">RFC</a> <a rel="nofollow" class="external text" href="https://www.rfc-editor.org/rfc/rfc9114">9114</a>.<a href="#cite_note-rfc9114-1">[1]</a>

<div class="mw-heading mw-heading2"><h2 id="Comparison_with_HTTP/1.1_and_HTTP/2">Comparison with HTTP/1.1 and HTTP/2</h2></div>

HTTP semantics are consistent across versions: the same <a href="../Hypertext_Transfer_Protocol" class="mw-redirect" title="Hypertext Transfer Protocol">request methods</a>, <a href="../Hypertext_Transfer_Protocol" class="mw-redirect" title="Hypertext Transfer Protocol">status codes</a>, and <a href="../List_of_HTTP_header_fields" title="List of HTTP header fields">message fields</a> are typically applicable to all versions. The differences are in the mapping of these semantics to underlying transports. Both <a href="../HTTP/1.1" class="mw-redirect" title="HTTP/1.1">HTTP/1.1</a> and <a href="../HTTP/2" title="HTTP/2">HTTP/2</a> use <a href="../Transmission_Control_Protocol" title="Transmission Control Protocol">TCP</a> as their transport. HTTP/3 uses <a href="../QUIC" title="QUIC">QUIC</a>, a <a href="../Transport_layer" title="Transport layer">transport layer</a> <a href="../Network_protocol" class="mw-redirect" title="Network protocol">network protocol</a> which uses <a href="../User_space" class="mw-redirect" title="User space">user space</a> <a href="../Congestion_control" class="mw-redirect" title="Congestion control">congestion control</a> over the <a href="../User_Datagram_Protocol" title="User Datagram Protocol">User Datagram Protocol</a> (UDP). The switch to QUIC aims to fix a major problem of HTTP/2 called "<a href="../Head-of-line_blocking" title="Head-of-line blocking">head-of-line blocking</a>": because the parallel nature of HTTP/2's multiplexing is not visible to TCP's <a href="../Packet_loss#Packet_recovery_for_reliable_delivery" title="Packet loss">loss recovery mechanisms</a>, a lost or reordered <a href="../Network_packet" title="Network packet">packet</a> causes all active <a href="../Transaction_processing" title="Transaction processing">transactions</a> to experience a stall regardless of whether that transaction was impacted by the lost packet. Because QUIC provides native multiplexing, lost packets only impact the streams where data has been lost.
