RoundCube is a web-based IMAP email client written in the PHP programming language. RoundCube's most prominent feature is the pervasive use of Ajax technology to present a more fluid and responsive user interface than that of traditional webmail clients. After about two years of development, the first stable release of RoundCube was announced in early 2008. Released under the GNU General Public License, RoundCube is free software.
