What is StackSpend?

StackSpend is a cloud and AI cost management platform that connects to AWS, GCP (Google Cloud), Azure, Snowflake, Vercel, ClickHouse Cloud, Elastic Cloud, OpenAI, Anthropic, Cursor, GitHub, Hugging Face, Grok (xAI), and Twilio. It provides unified spend visibility, daily anomaly alerts, budget forecasting, and Slack or email delivery for engineering and FinOps teams. Setup takes 5 minutes with read-only credentials, and 90 days of historical data loads automatically. Plans start from $29/month with a free 14-day trial that doubles as a cost health audit of your stack.

Operating lifecycle

Forecast. Budget. Detect. Act. Save.

Financial discipline, built into how your engineers already work — so cloud spend stays predictable and overruns get corrected, not just explained.

Spend lifecycle, drawn as a chartA daily spend line is tracked to today, a forecast band with a budget guardrail projects forward, the line breaches the guardrail (an anomaly is detected), an alert and ticket are raised, then the line drops back into the band and the avoided overrun is saved.

Daily spend is tracked and projected forward with a confidence band.

This cycle, $4,962 of overspend was caught and avoided.

Intelligence built in

AI that automates spend control.

Watch it work a case. The spike is compared, isolated, traced to the pull request, and sized — then the fix arrives with a ticket. No dashboard babysitting, no month-end archaeology.

That’s Signal, the agent behind StackSpend — ask it anything about your spend, every figure cited, write actions only after you confirm.

Forecasting

ML forecasts you can footnote.

A time-series model (Prophet) with confidence bands and a days-to-risk date — per provider and org-wide.

Anomaly detection

Baselines, not guesswork.

Statistical baselines per provider and service; deviations scored and ranked by severity the same day.

Auto-categorization

Every line item, classified.

Known services map instantly; unknown ones are classified by an LLM with a confidence score — and the mapping is learned for next time.

Free cost risk audit

See where your spend is leaking — before the next invoice.

You can't fix the cost risk you can't see — and every day it runs unchecked, it's still billing. Run a free audit: connect your providers with read-only access and StackSpend surfaces the spikes, unguarded budgets, and runaway costs across your cloud and AI stack, so you catch them before the next invoice lands.

Common questions

FAQ — cloud and AI cost questions, answered

What is StackSpend?
StackSpend is a cloud and AI cost management platform for engineering and finance teams. It connects to AWS, OpenAI, Snowflake, and 11 more cloud and AI providers with read-only credentials, then gives you one view of spend, same-day anomaly alerts, budgets, and month-end forecasts — delivered to Slack, Microsoft Teams, or email. Setup takes about 5 minutes per provider, 90 days of history loads automatically, and plans start from $29/month with a 14-day free trial.
What is the best way to track AI and cloud costs in one place?
Track them in a single platform that covers both, instead of stitching a cloud-only cost tool together with each AI vendor's separate dashboard. StackSpend unifies cloud (AWS, GCP, Azure), data (Snowflake, ClickHouse Cloud, Elastic Cloud) and AI/LLM spend (OpenAI, Anthropic, Cursor, Hugging Face, Grok) in one view, with cross-provider anomaly detection, budgets and forecasts. It connects with read-only keys in about 5 minutes and backfills 90 days, so you see the full cost of running your product on day one.
How do I track OpenAI, Anthropic, and other LLM API costs?
Connect each provider with a read-only API key. StackSpend pulls daily spend, loads 90 days of history, and sends a Slack, Teams, or email digest every morning. Set a budget and StackSpend alerts you the same day when LLM spend spikes above its baseline — so a runaway prompt or traffic surge does not first surface on next month's invoice. OpenAI, Anthropic, Cursor, Hugging Face, and Grok (xAI) are supported today.
How do I get alerted about unexpected AWS or cloud charges?
StackSpend connects to AWS, GCP, and Azure billing with read-only credentials, builds a statistical baseline per service, and flags spikes the same day — by Slack, Teams, email, or webhook, before the invoice lands. Each alert carries a severity and a deviation percentage, and on the Business plan it is correlated to the GitHub deploy or pull request most likely behind it.
What is AI COGS, and how do I track AI gross margin?
AI COGS (cost of goods sold) is the inference cost embedded in your product — the OpenAI, Anthropic, or Bedrock spend behind each feature or customer interaction. StackSpend lets you tag costs by feature, team, or customer, so you can see gross margin per product line and watch how AI inference moves your unit economics as you scale.
Which cloud and AI providers does StackSpend support?
StackSpend supports AWS, GCP (Google Cloud), Azure, Snowflake, Vercel, ClickHouse Cloud, Elastic Cloud, OpenAI, Anthropic, Cursor, GitHub, Hugging Face, Grok (xAI), and Twilio. Each connects via read-only credentials or billing exports, and GitHub source control (deploys and pull requests) connects on the Business plan. New providers are added regularly.
How much does StackSpend cost?
Plans start from $29/month, with a free 14-day trial and no credit card required. The trial doubles as a free cost health audit of your stack — connect your providers and get full visibility before committing to a paid plan. Visit the pricing page for full plan details.
How long does StackSpend take to set up?
About 5 minutes per provider. You connect read-only credentials, verify the connection, and StackSpend backfills up to 90 days of history automatically and updates daily — no manual exports, and no changes to your accounts.
Can I ask StackSpend questions about my spend?
Yes. StackSpend includes a Cost Intelligence Agent — an in-app AI cost analyst. Ask in plain English ("what drove our bill up this week?", "are we on track against budget?", "draft a board summary") and it answers in seconds with cited figures across every connected provider, and can take confirmed actions like acknowledging an anomaly or creating a budget. It is the FinOps analyst smaller teams do not have to hire.
Can finance see costs in GBP or EUR, mapped to the P&L?
Yes. Most providers bill in USD, but StackSpend converts spend at historical exchange rates and reports in your organisation's preferred currency — USD, GBP, EUR, and more — and maps provider line items to P&L buckets (Cloud, AI, SaaS). Finance gets a number it can defend in planning instead of raw service names.
Can StackSpend turn cost spikes into tickets in Slack, Linear, or Jira?
Yes. Anomalies and budget reviews are delivered to Slack, Microsoft Teams, or email, and become tickets in Linear or Jira — assigned to the owning engineer and synced both ways, so closing the ticket resolves the anomaly. Cost work happens where your team already works, not in a separate dashboard one person has to watch.

Bring your stack. See your spend clearly.

Setup takes minutes. Connect providers, get 90 days of visibility, and start receiving daily cost updates before the invoice lands.
