In this article, we will look at how DrP works on a high level and the design choices Meta made while building it.

ByteByteGo provides tutorials, articles, and resources for learning and mastering the Go programming language, covering topics such as syntax, concurrency, and best practices. Developers can learn about Go programming fundamentals, web development with Go, and building scalable applications using Go's powerful features and standard library.

Meta built DrP, an internal platform that treats debugging and incident investigation as engineered software rather than tribal knowledge. Engineers write 'analyzers' using an SDK — codified investigation workflows that go through code review, CI/CD, and automated backtesting. Analyzers chain across service boundaries in microservices environments, trigger automatically on alerts, and surface structured findings to on-call engineers before they open a single dashboard. The platform now runs 50,000 automated analyses daily across 300 teams, with over 2,000 analyzers in production, reducing mean time to resolve incidents by 20-80%. The core insight is that investigation expertise can be codified into testable, composable software rather than living in runbooks or people's heads.
