Software Heritage

Software Heritage is a European-funded effort to archive software source code of all kinds, including all the versions thereof. It offers instant saving of individual repos and regularly saving all repos on a forge. The archive is publicly available and the LWN article "Preserving the global software heritage" gives more details.

Other software archives include:

• Codearchiver
• GitHub
• https://snapshot.debian.org/ (archive of all Debian history including binaries and source code)
• https://archive.org/details/software (focuses on binaries and the most ephemeral software; open submission)
• http://openhub.net/ (focused on analysis; open submission)
