KLone, an open-source (GPL) Embedded Web Server. A fully-featured, multiplatform, web application development framework,targeted especially for embedded systems and appliances. It is a self-contained solution which includes a web server and an SDK for creating stand-alone WWW sites with both static and dynamic content. It blends the HTTP/S server application together with its content and configuration into a single executable file. The site developer writes his/her dynamic pages in C/C++ (in usual HTML scripting style) and uses KLone to transform them into embeddable, compressed (and possibly ecrypted) native code with the native C/C++ compiler. The result is then linked to the HTTP/S server skeleton to obtain one single, ROM-able, binary file. Given its nature, it can be linked natively to any C/C++ library (database, XML, graphics, etc.), without an intermediate layer. Its main (yet not sole) use case consists of providing web based User Interfaces (UI) for configuration,monitoring and software upgrades of small devices. KLone has been ported to Windows, Linux, *BSD, MacOSX, QNX, VxWorks as well as x86, ARM, MIPS, PowerPC, SH and Cris processors.
