When an alarm fires, Whistlrr investigates for you — pulling metrics, logs, traces, and recent deploys into a single AI-generated root cause report. Delivered to Slack before your on-call opens their laptop.
No credit card required · Free plan includes AI investigations
A CPU spike was triggered by database connection pool exhaustion immediately following deployment v2.4.1 at 14:32 UTC. The payment service began retrying failed transactions, compounding CPU load. No hardware fault or external traffic spike detected.
v2.4.1 removed connection pooling config. RDS DatabaseConnections peaked at 498/500.
Sentry shows 1,240 payment.process errors in 5 min window, each triggering 3 retries.
Roll back v2.4.1 and restore DATABASE_POOL_SIZE=25 env var. ETA to recovery: ~8 min.
Example investigation — generated automatically when your alarm fires
Under the hood
One alert fires. The AI fans out across your entire stack — pulling correlated signals from every source simultaneously.
How it works
Whistlrr works while your team sleeps.
A CloudWatch alarm breaches, a Datadog monitor triggers, or a webhook fires. Whistlrr receives it instantly — no polling, no delays.
The AI agent queries all your connected data sources — metrics, logs, error rates, and recent commits — correlating everything across the incident time window.
A confidence-scored root cause report lands in your Slack channel — with correlated evidence, a timeline of events, and actionable next steps. Average time: under 5 minutes.
Integrations
The AI pulls data from everywhere your incidents leave traces — not just one vendor.
Why Whistlrr
PagerDuty AIOps costs $35+/user/month and takes months to set up. Whistlrr connects in minutes and starts at $13.
Connect your AWS account with an IAM Role (no long-lived keys), add your Datadog and Sentry tokens, and your first investigation fires automatically.
Datadog's AI only looks at Datadog data. Whistlrr correlates across every source — so you find the GitHub deploy that triggered the CloudWatch alarm.
Every investigation is interactive. Ask "what other services were affected?" or "when did this last happen?" — the AI already has all the context.
AWS access via IAM Roles, not long-lived keys. Cross-account isolation with External IDs. Your data is never used to train models.
The average Whistlrr investigation completes in under 5 minutes. Your team spends time fixing, not digging through dashboards.
Use your own Anthropic API key to run unlimited investigations. Whistlrr's shared key is available as a fallback on all plans.
