Chalk

Chalk is an open-source observability tool created by Crash Override that provides full lifecycle visibility into your software development process. Chalk acts like GPS for your software, allowing you to easily see where software comes from and where it gets deployed.

Chalk collects, stores, and reports metadata about software from build to production. The connection is made by adding an identifying mark (which we call a chalk mark) into artifacts at build time, ensuring they can be easily validated and extracted later.

Core Capabilities

• Chalk Mark Insertion: Add chalk marks to software artifacts (binaries, containers, scripts) during build time
• Extraction: Extract marks from artifacts already in production
• Reporting: Generate comprehensive reports about artifacts and environments
• Runtime Monitoring: Configure heartbeat monitoring for deployed applications
• Supply Chain Security: Generate SBOMs, collect code provenance data, and provide digital signatures
