now tracing 50M+ requests a day

See every request,
before it becomes an incident.

TraceFlow is distributed tracing built for backend teams — follow a request across every service, span, and query, and know exactly where your latency lives.

Everything an on-call engineer actually opens

Six tools that share one trace model, so context never gets lost between them.

Distributed tracing

Follow a single request across every service boundary, queue, and database call — no more guessing where time went.

Request monitoring

Live throughput, error rate, and latency for every route, refreshed in real time.

Performance analytics

P50 to p99 percentiles, grouped by service, region, or deploy — spot regressions before your users do.

Custom spans

Wrap any function, job, or query with one line and see it appear in the trace tree instantly.

Error insights

Every exception linked back to the exact trace, span, and payload that caused it.

Team collaboration

Share a trace like a link. Annotate spans, tag teammates, resolve incidents together.

sdk

One import, full instrumentation

Drop the SDK into any Node, Python, or Go service. Auto-instruments your framework, database driver, and queue client — custom spans take one line.

  • Zero-config for Express, Fastify, Django, Gin
  • 5ms average overhead per request
  • Works alongside OpenTelemetry

from the field

Teams debugging faster, not harder

We replaced four dashboards with one trace view. Time-to-root-cause on incidents dropped from an hour to under ten minutes.

The SDK auto-instruments our whole Go stack. Custom spans for the weird internal jobs took an afternoon, not a sprint.

faq

Good to know

TraceFlow is built trace-first: every panel, alert, and chart is a view into the same span data, so you never lose context switching between tools.

Yes. TraceFlow can ingest OTLP directly, or you can use our SDK for automatic framework and driver instrumentation.

5ms on average per instrumented request, measured across our production customer base.

Enterprise plans support a dedicated ingest pipeline in your own VPC.
