Cloud and AI cost control your team actually uses.
Forecast, budget, and monitor cloud and AI spend automatically. StackSpend connects your providers to Slack, Linear, and Jira, turning cost risks into engineering actions and giving every team a daily view of spend health.
No credit card required. Read-only access. Daily Slack or email delivery.
See how it worksWhat is StackSpend?
StackSpend is a cost management platform for the modern AI engineering stack — it connects to OpenAI, Anthropic, Cursor, GitHub, Hugging Face, Grok (xAI), and the cloud it runs on: AWS, GCP (Google Cloud), Azure, Snowflake, Vercel, ClickHouse Cloud, Elastic Cloud, and Twilio. It provides unified spend visibility, daily anomaly alerts, budget forecasting, and Slack or email delivery for engineering and FinOps teams. Its AI Explorer shows LLM usage by model, project, and user across providers, and its model recommendations suggest cheaper models that match or beat the ones you use on published quality benchmarks, priced at your real token mix. Setup takes 5 minutes with read-only credentials, and 90 days of historical data loads automatically. Plans start from $79/month with a free 14-day trial that doubles as a cost health audit of your stack.
Forecast. Budget. Detect. Act. Save.
One control loop across your cloud, AI, data, developer, and comms providers: forecast where spend is heading, set budget guardrails, catch same-day when spend breaks pattern, and act before the invoice — or a board question — arrives.
See where month-end spend is heading across AWS, GCP, Azure, Snowflake, OpenAI, Anthropic, Cursor, and the rest of your stack — before the invoice lands.
Set provider and stack-level guardrails so cloud, AI, data, developer, and comms spend has a target before usage drifts.
Anomaly detection catches spend that breaks its baseline the day it happens — a runaway prompt, a forgotten cluster, a traffic surge — with a daily digest showing which providers moved.
Alerts route to Slack, Microsoft Teams, or email and become assigned tickets in Linear or Jira — the owning engineer fixes the spike instead of a dashboard just recording it.
Corrected overruns become a running record of avoided spend — numbers you can put in front of finance before they ask.

Where engineers already work.
Nothing new to adopt. Your whole stack flows in; alerts, tickets, budgets, and answers flow out to the tools your team already lives in. One read-only key. Zero new logins.
What it caught.
$5,000
an hour, and climbing
Stopped in two hours
A compromised service role was firing thousands of requests at Gemini endpoints. Nothing in the cloud console had raised it. A statistical baseline flagged the deviation, the role was revoked two hours later, and roughly £80,000 of burn never happened.
Caught on our own infrastructure.
~$800/day
AWS CloudWatch
A UAT warehouse hit a disk limit and began writing full stack traces to CloudWatch several times a second. The log group had no alerting configured. A statistical baseline flagged the deviation within two hours.
Billing corrected
Google Vertex AI
Vertex spend sat near zero for days, then jumped overnight with no change to usage or configuration. Flagged as an anomaly, raised with Google, and confirmed as a billing error on their side.
What it gave back.
“It probably takes me two days a month pulling info from different systems, and half a day from my boss. We certainly couldn’t do anything as cheaply as you provide it.”
How it knows.
Four things run against your data every day.
Forecasts you can footnote.
A time-series model (Prophet) with confidence bands and a days-to-risk date — per provider and org-wide.
Baselines, not guesswork.
Statistical baselines per provider and service; deviations scored and ranked by severity the same day.
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.
Cheaper models, checked daily.
StackSpend looks for models that match or beat yours on published quality benchmarks, prices them at your real token mix, and shows the projected saving.
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.
Free. Read-only access. No credit card. Findings the same day.
