Sourcegraph is a universal code search tool that helps developers navigate and understand their codebase across multiple repositories. Its latest extension, datadog-service-map, integrates with Datadog APM to provide insights into service dependencies and performance metrics within the code search workflow. This allows developers to easily locate impacted services, fix bugs, and apply changes across their entire codebase. The extension also enables seamless pivoting between Sourcegraph and Datadog APM for visual representation of application topology and real-time updates on service endpoints.
