Real-time explanation panel — from incident to root cause in seconds.
One import, one init call. Polydog automatically traces requests, captures logs, and starts explaining anomalies in real-time.
import { Polydog } from "@polydog/node"
Polydog.init({
service: "furn-demo",
endpoint: "https://gateway.polydog.io",
});
// ✓ Done. Traces, logs, and explanations
// are now flowing to Polydog.HOW IT WORKS
No configuration. No dashboards to build. Just answers.
One npm install and three lines of code. Polydog wraps your existing middleware and immediately starts collecting traces, logs, and metrics — no config files, no agent processes, no YAML.
// $ npm install @polydog/node
import { Polydog } from '@polydog/node'
const pd = new Polydog({
apiKey: 'pd_live_xxxx',
service: 'payment-service'
});
// Wrap your handlers
app.use(pd.middleware())Every request, DB query, and external call is automatically stitched into a single causal timeline using W3C traceparent propagation. No manual instrumentation needed across your services.
Polydog's causal engine analyzes every span, log, and event in the trace, then delivers a plain-English explanation with a confidence score and ranked action items — in under 2 minutes.
DB connection pool exhausted (50/50 connections in use). This caused order-service to timeout, triggering 41 retries from checkout-api.
Open Standards
Polydog uses OpenTelemetry natively. No vendor lock-in, no proprietary agents — your data, your way.
We were spending 45 minutes per incident manually correlating logs and traces. Polydog cut that to under 2 minutes. It's like having a senior SRE on call 24/7.

Drop-in replacement for your existing OpenTelemetry pipeline. Supports OTLP over HTTP and gRPC.
Latency anomaly and error rate detectors fire within seconds. Incidents are auto-opened before your pager goes off.
Trace waterfall with clickable span attributes, service maps, and metric correlation — all in one view.
Error budgets, burn rates, and 30-day cost attribution per service. Know what costs and what breaks.
Why Polydog
Other tools tell you that something broke. Polydog tells you why.

Testimonials
From startups to scale-ups — hear what on-call engineers say after their first incident with Polydog.
We went from 45 minutes of log diving to understanding the root cause in under 2 minutes. Polydog's causal graph is genuinely magical.

Finally, an observability tool that explains WHY something broke, not just THAT it broke. Our MTTR dropped 67% in the first month.

Platform Lead · Growthly
The Explain engine caught a subtle race condition that would have taken our team days to find. Saved us an entire incident post-mortem.
Priya R.
Engineering Manager · Nexaflow
We migrated from Datadog last quarter. The savings were significant, but what really won us over was the Explain engine. It found a subtle N+1 query bug that had been causing intermittent slowdowns for months. Our dashboards never would have caught it.

Staff Engineer · Healthtech Co
Our on-call rotation went from dreading alerts to actually feeling confident. Polydog tells you what's broken AND why AND what to do about it. That third part is what was always missing from every other tool.

We integrated in 20 minutes with the Node.js SDK. Had our first trace in the dashboard before lunch. The fact that it works out-of-the-box with zero configuration is remarkable.
