Infrastructure that points the way before users notice.
Cairn unifies metrics, traces, and logs into one timeline. When something shifts, you see what changed, why, and what to do next — not a wall of dashboards.

One signal, not a thousand dashboards
Most tools show you everything and explain nothing. Cairn correlates across your stack and surfaces the one thing worth your attention.
Unified timeline
Metrics, traces, and logs stitched into a single scrubber. Drag to any moment and see the full system state.
Change-aware alerts
Every alert links to the deploy, config change, or traffic shift that triggered it. No more guessing what moved.
Service maps
Auto-discovered topology that updates as you ship. Trace a request across every hop without instrumenting by hand.
Anomaly detection that learns your baseline
Cairn models the normal rhythm of each service — weekday peaks, batch jobs, regional traffic — and only pages you when reality breaks from its own pattern. Tuned per signal, not one global threshold.
Open by default
OpenTelemetry-native. Bring your existing exporters; keep ownership of your data.
Your whole stack, one pane
This is the surface your on-call engineer opens at 3am — built to answer the only question that matters: is it us, and what changed?
System health — last 6h
Three steps to your first signal
Drop in the agent
One binary, or a Helm chart for Kubernetes. Auto-detects your services and starts collecting in under two minutes.
Cairn learns the shape
For the first day it watches quietly, building a per-service baseline of what normal looks like — no thresholds to set.
Get pointed, not paged
When something breaks pattern, you get one alert with the change that caused it and the trace to prove it.
Pay for signal, not ingest
Flat per-host pricing. Send all the telemetry you want — we never bill you by the gigabyte.
