HyperDX

Open source observability platform that unifies session replays, logs, traces, metrics, and errors in one place for full-stack production debugging. Correlates every request from the browser and mobile clients through backend servers and async workers, with fast search powered by ClickHouse.

Acquired by ClickHouse to advance open source observability. Trusted by high-velocity engineering teams and positioned as an alternative to Datadog and New Relic for teams wanting unified telemetry without vendor lock-in. Uses OpenTelemetry for vendor-agnostic instrumentation and supports agent-free setups.

Key capabilities:

• End-to-end correlation from client session replays to backend traces and logs
• Full-text search across terabytes of events, no complex query syntax
• Automatic log pattern clustering to condense large volumes into distinct patterns
• Chart builder for visualizing logs, metrics, and traces with custom groupings
• Alerts via Slack, Email, and PagerDuty
• Native JSON parsing for structured logs without extra configuration
• Instrumentation for Node.js, Python, Java, Go, Elixir, Browser, React Native
• Deployment guides for Kubernetes, Vercel, Fly.io, Heroku, Cloudflare, AWS

Engineers use HyperDX to debug production issues by jumping from a user session replay into the exact backend logs and traces, to trace API requests and database queries with minimal instrumentation, and to search across all telemetry with plain text instead of proprietary query languages.
