kCalDAV is a simple, safe, and minimal CalDAV server depending only on kcgi(3), SQLite, and expat(3). The ISO C source code is ISC licensed. For the time being, it works only for simple setups, for example, a calendar collection shared between Mozilla Lightning, Mac OS X iCal, and iOS7 (iPhone4) clients. It compiles and runs on OpenBSD, Linux, and Mac OS X: see the Makefile for examples. This is the README file for display with GitHub, which hosts a read-only source repository of the project. To keep up to date with the current stable release of kCalDAV, visit the kCalDAV website. You can still submit bug reports here, however.
