HyperDX

HyperDX is an open source observability platform that brings together logs, traces, metrics, and session replays into a single interface. It helps engineering teams quickly identify and resolve issues in their production applications by providing a unified view of what's happening across their entire stack. Instead of juggling multiple tools, you can see the full picture of an error or performance problem from the user's browser all the way to your backend services. The platform is designed to be both powerful and accessible, with a focus on making complex debugging tasks straightforward. It uses ClickHouse for storage, which enables it to search through massive volumes of data very quickly. A key feature is its automatic correlation of session replays with backend logs and traces, so you can watch a user's session and simultaneously see the corresponding server-side activity. The search syntax is simple and intuitive, allowing you to find what you need without learning a complex query language. HyperDX also automatically clusters similar log events, making it easier to spot patterns in noisy data. This tool is built for engineering teams that need to maintain high application reliability without the high cost of traditional observability vendors. It is particularly useful for teams running web applications or services where understanding the full user journey is critical. Real-world use cases include diagnosing a specific customer's reported bug by replaying their session and seeing the exact errors that occurred, or identifying a performance bottleneck by tracing a slow request through all the microservices it touched. The open source foundation and OpenTelemetry support mean you can instrument your applications without worrying about vendor lock-in.
