Runtime Metrics
Find the runtime bottleneck behind slow response times
Correlate event loop delay, heap usage, external memory, active handles, and GC pauses with the requests they affected.
Node.js Monitoring
See exactly what's blocking your event loop
Debug slow routes, catch memory leaks in long-running services, and trace requests across your entire Node.js stack. Built natively on OpenTelemetry with no proprietary agent or SDK.

What I love most about Dash0 is that it's fully OpenTelemetry native which has significantly improved our software development process. The seamless navigation from logs to traces to metrics streamlines bug diagnosis and troubleshooting, enhancing our team's efficiency.
Elliot Dauber
Software Engineer - Vercel
The tracing UI is amazing. When we switched to Dash0, it significantly cut down the amount of time from a bug being reported to figuring out why it happened and fixing it. Filtering on attributes is extremely intuitive, and the tracing tree UI is awesome.

Dash0's foundation on open source standards ensures future-proof and next-gen observability. Their focus on ease of use empowers all of our developers to gain insights quickly.
Catch memory leaks and event loop stalls before they page you at 3am
See when Node is blocked, leaking memory, or losing async context, with runtime metrics and traces in one place.
Async Context
Traces that follow your async/await chains
Traces that propagate through Promises, async/await, and EventEmitters. The full async flow across services, not just HTTP in and out.
Connect the signal to the incident
Logs, traces, metrics, and alerts in one connected view. Click from one to any other.
Signal Correlation
Jump from a log line to the trace that produced it
Click from a log line to its trace, then jump from a span to the underlying metrics. OpenTelemetry's trace-context correlation and Dash0's resource-centric design make it automatic, no manual linking.
Alerting
Get alerted before your users notice
Define checks on Node.js latency, error rates, or event loop lag using PromQL or the query builder. Reuse open-source alert rules from Awesome Prometheus Alerts and get notified via email, Slack, or any webhook.
Start seeing telemetry in minutes, not days
Install the OpenTelemetry auto-instrumentation package, set a NODE_OPTIONS env var, and point it at Dash0. No code changes required.
Setup
npm install, set env vars, done
Install @opentelemetry/auto-instrumentations-node and activate it via NODE_OPTIONS. The SDK loads before your app and instruments popular libraries automatically.
Kubernetes
Zero-code instrumentation via the Dash0 Operator
The open-source Dash0 Operator auto-instruments Node.js pods on Kubernetes. Install with Helm, enable monitoring on your namespace, done.
Agent Skills
Teach your coding agent OpenTelemetry
Open-source skills for Claude Code, Cursor, Windsurf, and 38+ other AI coding agents. Correct resource attributes, span status codes, and Collector patterns from the first commit.
Future-proof your observability stack
No proprietary agents and no vendor-specific code in your repo, just standard OpenTelemetry from instrumentation to export to query.
OpenTelemetry
Vendor lock-in is a thing of the past
Dash0 is designed as an OpenTelemetry-native observability platform. Your instrumentation uses the official OTel JS SDK — semantic conventions and resource attributes preserved as-is, enabling standardized data collection across distributed systems.
PromQL + SQL
Bring your existing Prometheus alerts, or write SQL
Import your existing Prometheus alerts and query traces, logs, and metrics with PromQL or SQL.
Portable Artifacts
Dashboards, alerts, and configs you can take with you
Perses-compatible dashboards, PromQL alert rules, and OTel Collector configs. Everything Dash0 produces is an open-standard artifact you can commit to git.
