Chalk™ is the open source engine that powers our platform. Chalk captures metadata at build time and can inject a small 'chalk mark' to any artifacts, such as source code, binaries and containers.
Chalk™ can extract these 'chalk marks' and collect other metadata about the operating environment at run time.
You can read about how chalk can be used by developers, site reliability engineers and security pros here.
By collecting and correlating 'chalk marks' with your source code management system and cloud service provider, you can understand exactly what and where your source code is deployed.
Chalk™ is released under GNU GPL version 3.0 license.
