Cloud spend anomaly detection across AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud — catch spikes before month-end.
StackSpend detects cloud cost anomalies across AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud in one monitoring loop. Daily baseline comparison fires Slack, email, or webhook alerts the day a spike starts — so you investigate the same day instead of discovering overruns at invoice time.
See the overspend before the invoice does.
StackSpend projects where the month lands from daily actuals. When the dashed forecast crosses your budget, you get the alert — not the surprise.
Spend vs Budget
Forecast $61,000 this month

AWS / NAT Gateway — $891 vs $286 expected (+212%)
How it works in practice
StackSpend connects to AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud with read-only access. Daily spend is compared against your historical baseline — statistical anomaly detection, not just fixed thresholds.
Anomaly alerts delivered to Slack or email the same day a spike starts. Webhooks push anomaly.created events to your endpoint for incident runbooks or PagerDuty routing.
Budget tracking and pace-to-forecast add context. See whether a cloud spike is noise or the start of a material overrun before the billing cycle closes.
When this use case fires
A misconfigured autoscaling policy keeps instances running overnight and through a weekend
A data pipeline cron expression changes and the job runs 12× more often than intended
Dev environment resources from a sprint are never torn down — they run for months
Reserved instance coverage lapses and on-demand rates apply from day one without an alert
Cloud costs drift before they spike. Misconfigured jobs, autoscaling policy changes, or dev environments left running quietly push spend upward. Native billing dashboards do not surface these patterns until the bill is already high.
AWS Budgets, GCP Budget Alerts, and Azure Cost Alerts each have their own alert setup. Cross-cloud anomaly detection requires three separate configurations — and even then, each fires after the budget is already exceeded.
By the time finance reviews the invoice, the overspend has been committed for weeks. Without daily monitoring and early warning, the only response is retroactive explanation.
How StackSpend does this
AWS Budgets, GCP Budget Alerts, Azure Cost Alerts is built for different jobs. Here is what StackSpend adds.
AWS Budgets, GCP Budget Alerts, Azure Cost Alerts
- Each cloud has its own alert system — no unified cross-cloud detection
- Budget alerts fire after the threshold is already exceeded
- No statistical anomaly detection — only fixed threshold triggers
- No cross-cloud view of where the spike came from
StackSpend
- Daily anomaly detection across AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud together
- Statistical baseline — catches unusual patterns before budgets are blown
- Unified alerts across all cloud providers via Slack, email, or webhook
- Catch spikes the day they happen, not at month-end invoice
What we track
Who uses this
Teams trying to catch spend spikes before finance closes the month.
Operators who need alerts, escalation paths, and budget-aware follow-up instead of passive reporting.
Buyers comparing native provider alerts with a cross-provider monitoring workflow.
