Cartes du Ciel ("CDC" and "SkyChart") is a free and open source planetarium program for Linux, macOS, and Windows. With the change to version 3, Linux has been added as a target platform, licensing has changed from freeware to GPLv2 and the project moved to a new website.

CDC includes the ability to control computerized GoTo telescope mounts, is ASCOM and INDI compliant, and supports the USNO's UCAC catalogs and ESA Gaia data, along with numerous other catalogs and utilities.

According to the programmer, Patrick Chevalley, it was released as freeware because "I’d rather see amateurs spend their money for a new eyepiece than for astronomy software".

Chevalley has also created a lunar atlas program, Virtual Moon Atlas, which is also free and open source software.
