Connected providers · daily spendIllustrative product view
Every provider in one view. The product’s daily spend-by-provider chart: see the composition of your bill across your connected providers, with the daily-budget line — so a spike shows up the day it happens, and you can see which provider caused it.

See what is driving your spend.

Daily signal in Slack

One message each morning. Nobody opens a billing portal.

One message each morning in Slack or email: yesterday's spend, budget pace, anything unusual. Green means on track — most days nobody has to think about cost at all, which is the point. Microsoft Teams support is planned.

Anomaly detection

Catch the spike the day it starts.

StackSpend learns what normal looks like per provider, account and service, then flags the day something breaks pattern, with a severity and an owner. Each one carries a lifecycle, so it gets closed.

How it works

Product examples are illustrative. Usage estimates and provider-reported costs are separate measures; availability varies by connected source.

Why is this spend hard to control?

  • AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud each have their own dashboards and billing cycles. Cost Explorer, BigQuery billing export, Cost Management, Snowflake organization usage, Vercel billing, and ClickHouse Cloud usage views are powerful—but they're investigation tools, not prevention tools. You have to log in to each one to see the full picture.
  • Surprise bills happen when no one checks. Dashboards don't send alerts. By the time you notice a spike, the month is over and the overrun is real.
  • Cross-provider visibility requires manual aggregation. If you run multi-cloud, you're adding up three different invoices—or three different dashboards—to understand total spend and manage cloud spend confidently.

Know what you are connecting.

The coverage

  • StackSpend connects to AWS (Cost Explorer API), GCP (BigQuery billing export), Azure (Cost Management API), Snowflake (organization usage billing views), Vercel (FOCUS billing charges), and ClickHouse Cloud (Usage Cost API) with read-only credentials. One dashboard shows total cloud spend and breakdown by provider, service, and project.
  • Daily signals arrive in Slack or email. Green means on track. Amber or red means attention needed. No logging in required.
  • Anomaly detection compares today's spend to your baseline. Alerts via Slack, email, or webhooks — push anomaly.created events to your own systems. Pace-to-forecast tells you where the month will end. Catch overruns before they happen.
  • For teams searching for cloud spend management rather than just raw billing exports, StackSpend adds the daily monitoring and reporting loop that native dashboards usually miss.

The source

Billing and usage from your connected providers. Credential types and permission controls vary by provider.

Provider connection guides

The limits

Provider reporting and scheduled sync determine freshness. Available history and attribution vary by source; review the setup guide for coverage. Alerts notify your team; they do not block requests or enforce a spending cap.

What we track

  • AWS (Cost Explorer, Organizations multi-account)
  • GCP (BigQuery billing export)
  • Azure (Cost Management API)
  • Snowflake (organization usage billing views)
  • Vercel (FOCUS billing charges)
  • ClickHouse Cloud (Usage Cost API)
  • 90 days of history
  • Daily rollups and forecasts

Who is this for?

  • Engineering leaders running multi-cloud workloads who need one cost view instead of three billing portals.
  • Platform and DevOps teams that want daily alerts when cloud spend spikes — without manually checking dashboards.
  • Finance and CTOs who need accurate cloud cost forecasting before month-end to avoid budget surprises.

    Review the first 90 days

    Check history, alerts, anomalies, and forecast so you can decide whether the workflow is worth adopting.

StackSpend alongside native billing tools.

Native tools provide provider-specific reporting and controls. StackSpend adds a shared monitoring workflow across connected sources.

AWS Cost Explorer, GCP Cloud Billing, Azure Cost Management

  • Three separate portals — you have to log into each one to see the full picture
  • Native budgets support notifications; rules and recipients are configured separately in each cloud
  • Cross-provider total requires manual aggregation or spreadsheet work
  • Native alerts use each provider’s billing data and delivery cadence; they do not combine your other vendors

StackSpend

  • One dashboard for AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud in a single view
  • Daily Slack or email signal — green/amber/red, no logging in required
  • Cross-provider anomaly detection catches spikes the day they happen
  • Pace-to-forecast tells you where the month will end before it does

Cloud Cost Monitoring, answered

What causes Cloud Cost Monitoring costs to spike?
  • An EC2 instance type is deployed in a dev environment without a lifecycle policy and runs for weeks
  • GCP data transfer costs spike after a new service-to-service integration is added
  • Azure reserved instances expire and pay-as-you-go rates apply silently from day one
  • An S3 bucket accumulates storage well beyond planned capacity with no one checking
What is StackSpend for Cloud Cost Monitoring?

StackSpend is a cloud cost monitoring platform that connects AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud with read-only credentials. Get a daily cost signal in Slack or email — green, amber, or red — so your team has cloud cost visibility and knows whether cloud spend is on track without opening a single billing portal. Anomaly detection, budget tracking, and spend forecasting included from day one.

How do you control cloud costs?

Cloud cost control starts with a daily loop, not a quarterly cleanup: one view of AWS, GCP, and Azure spend, budgets with 50/80/100 percent alerts, anomaly detection against your own baseline, and a month-end forecast that updates every morning. StackSpend adds that loop on top of read-only billing connections, so overruns are caught while they are still small.

Why is my cloud bill suddenly so high?

Sudden cloud bill increases usually trace to one of four causes: resources left running after their purpose ended (dev instances, idle endpoints), a usage pattern change (a retry loop, new traffic path, or data transfer after a refactor), a pricing or tier change (a model upgrade, expired reserved instances, or a vendor price change), or new usage nobody attributed (a team adopting a tool on its own). The bill looks sudden because the change ran unnoticed for weeks — the cause almost always started well before the invoice.

How do I stop surprise cloud and AI bills?

Watch spend daily against a baseline instead of monthly against an invoice. StackSpend connects your cloud and AI providers read-only, builds a 90-day baseline, and sends a same-day Slack or email alert when any service, model, or project breaks pattern — so the fix happens while the overrun is hours old. Setup takes about 5 minutes, with a free 14-day trial and plans from $79/month after.

How do I know whether cloud spend is on track without opening a billing portal?

StackSpend sends a daily cloud cost signal to Slack or email — green, amber, or red — across AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud, connected with read-only credentials. Anomaly detection fires the day a spike starts and pace-to-forecast shows where the month will land, so your team knows the answer at a glance instead of logging into Cost Explorer, BigQuery billing, and four other dashboards.

Does StackSpend support multi-cloud cost monitoring?

Yes. StackSpend connects to AWS via Cost Explorer, GCP via BigQuery billing export, and Azure via the Cost Management API. All three appear in one dashboard with a combined total.

How is this different from AWS Cost Explorer or native cloud billing dashboards?

Native cloud billing dashboards are investigation tools — you have to log in to look. StackSpend is a monitoring layer that delivers a daily signal to Slack or email, fires anomaly alerts the day a spike starts, and gives you pace-to-forecast so overruns are visible before the month closes.

How long does cloud cost monitoring setup take?

Most teams can connect a cloud provider in under 10 minutes with read-only credentials. StackSpend never modifies your infrastructure or billing settings. 90 days of history is backfilled automatically on connect.

Can I get alerts when cloud spend spikes?

Yes. StackSpend uses anomaly detection to compare daily spend to your historical baseline. Alerts are delivered via Slack, email, or webhook so you can respond the same day instead of discovering the spike at invoice time.

What is cloud cost visibility and how does StackSpend provide it?

Cloud cost visibility means seeing total cloud spend and its breakdown — by provider, service, and project — in one place, continuously, rather than logging into each billing portal. StackSpend gives you that visibility as a single dashboard plus a daily green/amber/red signal across AWS, GCP, Azure, Snowflake, Vercel, and ClickHouse Cloud.

How do I track total cloud spend across providers?

StackSpend normalizes cloud spend from every connected provider into one combined total and breaks it down by provider, service, and project. You see the all-in number and what is driving it without manually adding up separate invoices or dashboards.

Does StackSpend forecast cloud spend?

Yes. Pace-to-forecast projects where the month will land based on spend so far, so you get a spend forecast mid-month — early enough to act — instead of finding out the cloud budget was blown at invoice time.
