What does StackSpend do?

StackSpend is a cloud and AI cost monitoring platform. It connects to 13 providers — AWS, GCP, Azure, Snowflake, Vercel, ClickHouse Cloud, Elastic Cloud, OpenAI, Anthropic, Cursor, GitHub, Hugging Face, Grok (xAI), and Twilio — with read-only credentials, normalises every bill into one daily number, and categorises spend to P&L buckets. It gives you a unified dashboard and data explorer, Prophet-powered forecasting, budgets with alerts at 50/80/100%, and statistical anomaly detection. On the Business plan it traces each spike to the GitHub deploy or pull request most likely behind it. It delivers to Slack, Microsoft Teams, and email, opens assigned tickets in Linear and Jira, exposes a REST API and webhooks, and includes an in-app cost intelligence agent. Read-only, AES-256 encrypted, tenant-isolated, and GDPR compliant. Setup takes about 5 minutes with 90 days of history loaded automatically; plans start at $29/month.

Make it make sense

A single daily signal in Slack or email, a dashboard with traffic-light spend health, and a data explorer to drill any dimension — provider, service, tag, project, or user — then group, chart, and export exactly the slice you filtered.

  • Unified dashboard · MTD and projected month-end at a glance
  • Data explorer with drill-down, group-by, and CSV export
  • Tagging & auto-tag rules attribute cost to teams at ingest

03Forecast & budget

Know month-end on day 9

A Prophet-powered forecast with confidence bands and a days-to-risk date, per provider and org-wide. Budgets scope to anything; auto-budgets seed the numbers from your own history; alerts land at 50, 80, and 100% before the breach, not after.

  • Forecast with confidence intervals and a breach date
  • Budgets per org, provider, project, or tag — in any currency
  • Auto-budgets from your historical spend
How forecasting works
04Detect & trace

Catch the spike — and what shipped itBusiness

Statistical baselines flag the anomaly the same day. Then — the part a dashboard can't do — StackSpend links it to the GitHub deploy and pull request most likely behind it, ranked by confidence, so the engineer who shipped it sees it first.

  • Spike, drop, trend-change, and new-service detection with severity
  • Root-cause: the spike arrives attached to the deploy and PR behind it
  • Ranked by confidence — evidence, never asserted. You confirm.

05Act where you work

The work lands where engineers already are

Alerts arrive in Slack, Microsoft Teams, or email. The work to fix a spike becomes a ticket in Linear or Jira — assigned to the owner, synced both ways, with the saving posted back when it resolves. Or wire it into anything with webhooks and the API.

  • Slack, Microsoft Teams, and email delivery
  • Linear & Jira: assigned tickets, two-way status, savings comment
  • Webhooks and a REST API for runbooks, PagerDuty, and custom flows

Built for the AI era

AI spend, tracked to the token — with an agent that explains it

AI is the fastest-growing line on the bill and the hardest to read. StackSpend tracks OpenAI, Anthropic, Cursor, Hugging Face, and Grok at the token and model level, folds it into the same P&L view as your cloud, and puts an analyst on top of it.

  • Token- and model-level cost across every AI provider
  • AI spend normalised alongside cloud, in one number
  • Per-team and per-product AI attribution via tags
  • Anomaly detection tuned to spiky, usage-based AI bills

✦ Cost Intelligence Agent

Ask, and it answers with receipts

Plain-English questions get analyst-grade answers with cited figures. The agent chains the queries, explains the variance, and — only after you confirm — takes the action: acknowledging anomalies, creating budgets, drafting a board summary in your currency.

  • Multi-step analysis grounded in exact figures and dates
  • Every write action waits for your confirmation
  • Copy-ready board and P&L summaries, self-serve

Common questions

Feature FAQ

Does StackSpend cover both cloud infrastructure and AI/LLM providers?
Yes — that is the point of StackSpend. Infrastructure: AWS, GCP, Azure, Snowflake, Vercel, ClickHouse Cloud, Elastic Cloud. AI and LLM: OpenAI, Anthropic, Cursor, Hugging Face, Grok (xAI). Plus GitHub and Twilio. All connect with read-only credentials, and GitHub source control (deploys and pull requests) connects on the Business plan. New providers are added regularly.
Does StackSpend detect cost anomalies?
Yes. StackSpend builds statistical baselines per provider and service from your own history and flags spikes, drops, trend changes, and new services the same day — each with a severity level, a deviation percentage, and a full acknowledge/resolve lifecycle.
Can StackSpend tell me what caused a cost spike?
On the Business plan, StackSpend correlates each anomaly to the GitHub deploy or pull request most likely behind it — ranked by confidence from timing, the service touched, and the kind of change. It is evidence for an engineer to confirm, never asserted as the sole cause. GitHub today; more trackers coming.
Can I attribute costs to a team, feature, product, or customer?
Yes. StackSpend tags and groups costs by team, feature, product, or customer, so you can allocate spend, calculate AI COGS and gross margin per product line, and see who a cost belongs to without exporting CSVs. Mappings from services to categories and owners are derived automatically, and you can override any of them.
Does StackSpend forecast spend and enforce budgets?
Yes. StackSpend projects month-end spend from your run-rate with confidence bands, and budgets alert at 50%, 80%, and 100% of threshold — before you breach, not after. Auto-budgets are seeded from your own history, per provider and across the whole stack.
Does it integrate with Slack, Microsoft Teams, Linear, and Jira?
Yes. Daily digests and anomaly alerts are delivered to Slack, Microsoft Teams, or email. Anomalies and budget reviews become tickets in Linear or Jira — assigned to the owner and synced both ways, so closing the ticket resolves the anomaly.
Does StackSpend have an API, webhooks, and MCP?
Yes. A REST API under /api/v1/ exposes every figure the dashboard shows — line items, daily rollups, provider totals, and anomalies. Webhooks push anomaly and budget events to your endpoint to trigger runbooks, PagerDuty, or custom workflows, and the MCP server lets Claude Code and other AI agents query your cost data in natural language.
How is my cost data secured?
Connections are read-only and credentials are encrypted with AES-256. Every tenant is isolated with row-level security, all changes are audit-logged, and GDPR export and deletion are self-service.

Make cost something your engineers own — not something one person watches.

Connect providers in minutes. Get 90 days of visibility, same-day anomaly detection, and — on Business — the deploy behind every spike.
