Software Heritage is an ambitious nonprofit, entirely Free/Open Source Software (FOSS) project that aims at collecting, organizing, preserving for the very long term, and sharing all publicly available software in source code form, together with the corresponding complete development history (e.g., from a Version Control System) where available. The Software Heritage archive already contains about 5 billion unique source code files and 900 million commits, retrieved from more than 80 million software projects.
