The developers also claim to have doubled the webserver's speed. Appweb 3 runs on Linux, Windows 7, Vista and XP, Mac OS X, VxWorks, Free BSD and Windows CE. The server uses as little as 800 KBytes memory so that it is perfect for embedded devices. The build system provides full cross-compilation support for Windows, Linux and Mac OS X. Supported processors are ARM, MIPS, x86/x86_64, PowerPC, SuperH and Sparc. Next to the newest Linux kernel 2.6, Appweb also supports Linux 2.4.
Appweb 3 provides numerous webserver functions such as CGI, PHP and SSL. The project page shows the list of features. The software is under GPLv2 and also a commercial license with support and a warranty.
