Hud, founded in 2023, introduces itself as the world's first runtime code sensor designed to transform observability by dynamically gathering context on code behavior at both the function and business levels in live production environments. Unlike traditional observability tools that rely heavily on manual logs and traces, Hud focuses on efficiently capturing and analyzing function-level telemetry to quickly identify and resolve issues, minimizing data overload while providing automatic root cause context when problems arise. The company leverages ClickHouse Cloud for its architecture, opting for a columnar database to manage high cardinality and support real-time metadata correlation, which allows them to track code changes accurately and detect performance degradations. The rearchitected pipeline, now integrated within ClickHouse, enhances scalability and reduces latency by eliminating unnecessary network calls and memory bottlenecks, offering a more streamlined and dependable developer experience. Hud's unique approach bridges business-level issues with engineering details directly within the IDE, making it particularly useful as AI coding agents become more prevalent. As they continue to optimize their system, Hud maintains flexibility with deployment options and focuses on providing engineers with actionable insights into code behavior, aligning with their mission to revolutionize observability.
