Features
How StackSpend works in practice
Daily visibility, forecasting, anomaly detection, budget control, and API workflows — across every cloud and AI provider you use.
14-day free trial. No credit card required. Read-only provider access.
Daily visibility
One spend signal. Every morning.
You open Slack. One message. Total spend yesterday, month-to-date by provider, forecast direction, and whether anything needs attention. Red dot on OpenAI means a spike. Green on AWS means on track. No dashboard to open, no spreadsheet to check.
The daily digest includes per-provider totals, period-over-period change, forecast to month-end, and any anomaly flags. It arrives at the same time every day — in Slack, email, or both. Connected to your workspace in 2 minutes.

Forecasting & budget control
Catch overspend before it's locked
StackSpend projects your month-end total based on current trajectory. When your pace crosses a threshold — 80% of budget with 10 days remaining, for example — an alert fires to Slack, email, or both. You see the problem before the invoice is final.
Set thresholds per provider, per category, or across your whole stack. Configure escalation paths so the right person gets the right alert. Budget alerts include the current pace, projected overshoot, and which providers are driving the increase.
Forecasts update daily as new billing data arrives. No manual calculations, no end-of-month surprises. The goal is simple: know where you will land before the invoice locks.
How forecasting worksAnomaly detection & response
Detect. Notify. Respond.
StackSpend builds statistical baselines per provider and service. When daily spend deviates beyond your threshold — a sudden OpenAI spike, an unexpected GCP job, an Azure runaway — an alert fires immediately.

}Unified coverage
Every provider. One normalised view.
AWS, GCP, and Azure bill on different cycles in different currencies with different structures. OpenAI and Anthropic use token-based pricing. Cursor charges per seat. StackSpend normalises all of them into a single daily number so you can compare, forecast, and alert across your entire stack.

What StackSpend includes
Spend forecasting
Pace-to-forecast projects your month-end total based on current trajectory. See where you will land before the invoice locks and adjust in time.
Anomaly detection
Statistical baselines per provider and service. When spend deviates beyond your threshold, an alert fires to the right channel and the right owner.
Budget alerts
Set thresholds per provider, category, or across your whole stack. Get notified at 80%, 100%, or any custom level via Slack, email, or webhook.
Unified dashboard
All providers normalised into a single view. Filter by provider, service, category, project, or user. Drill from totals to line items without switching tools.
Learn more90 days of history
When you connect a provider, StackSpend automatically loads up to 90 days of historical data. Trends, anomalies, and spend drivers are available immediately.
Multi-provider normalisation
AWS, GCP, and Azure all bill differently — different cycles, different currencies, different structures. StackSpend normalises everything into a single daily number.
Connect providersAPI and webhooks
REST API for programmatic access to cost data. Webhooks push anomaly and budget events to your endpoint so you can trigger runbooks, PagerDuty, or custom workflows.
