Software Heritage is a universal archive of software source code, aiming to collect, preserve for the very long term, and share all publicly available source code, along with its development history (e.g., as stored in version control systems). The Software Heritage archive already contains over 27 billion unique source files and 5 billion commits, retrieved from more than 300 million software development projects. Hosted by the Inria Foundation, the Software Heritage initiative is a completely free and open-source (FOSS) and non-profit project.
