HAProxy is a free and open source software that provides a high availability load balancer and Proxy (forward proxy,[2] reverse proxy) for TCP and HTTP-based applications that spreads requests across multiple servers.[3] It is written in C[4] and has a reputation for being fast and efficient (in terms of processor and memory usage).[5]

HAProxy is used by a number of high-profile websites including GoDaddy, GitHub, Bitbucket,[6] Stack Overflow,[7] Reddit, Slack,[8] Speedtest.net, Tumblr, Twitter[9][10] and Tuenti[11] and is used in the OpsWorks product from Amazon Web Services.[12]
