FAQ
Frequently asked questions about StackSpend.
How much does StackSpend cost?
StackSpend offers Starter, Team, and Business plans. All plans include a 14-day free trial with no credit card required. API access is available on the Business plan. See the pricing page for current plan details and pricing.
What providers are supported?
StackSpend supports 15 providers: OpenAI, Anthropic, Claude (via OTel), Cursor, Grok (xAI), Hugging Face, AWS, GCP, Azure, GitHub, Snowflake, Vercel, ClickHouse Cloud, Twilio, and Codex (via OTel).
How often are costs synced?
Costs sync automatically every 6 hours. You can also trigger a manual sync from any provider page at any time.
Real-time providers — OpenAI, Anthropic, Grok, and Cursor — reflect data within minutes. Cloud batch providers such as AWS, GCP, and Azure have a 24–48 hour data latency imposed by the provider's own billing APIs.
How much historical data is loaded?
The amount of historical data loaded on first sync depends on the provider:
| Provider | History available |
|---|---|
| OpenAI, Anthropic, Grok | Full available history |
| AWS, Azure, Snowflake, Vercel, ClickHouse Cloud, Twilio | 90 days on first sync |
| Cursor | 6–7 days only (API limitation) |
| GCP | From the date you enabled BigQuery billing export (no backfill) |
| GitHub | From the date of connection |
| Claude, Codex (OTel) | From setup date only |
Is my data secure?
Yes. Credentials are encrypted at rest. All data is strictly isolated per organization — your data is never accessible to other StackSpend customers. StackSpend never stores your actual cloud data — only the cost and usage metadata returned by provider APIs.
What is anomaly detection and how does it work?
StackSpend automatically detects unusual spend patterns after every sync. It learns your normal baseline per provider and service, then alerts you when spend deviates significantly — a spike, unexpected drop, new service appearing, or trend change. Each alert is assigned a severity (low, medium, high, or critical) and shows the deviation amount.
See the Anomaly detection guide for more detail.
What is the Inbox?
The Inbox is your alert triage panel, accessible from the top bar. It groups alerts into sections:
- For you — alerts on providers you own.
- Escalated — owned alerts open for more than 3 business days, visible to admins.
- Needs attention — unowned alerts.
- Set up — onboarding tasks.
- Opportunities — providers with no budget or owner assigned.
See the Inbox guide for more detail.
Can I connect multiple AWS accounts?
Yes. StackSpend supports multi-account setups via AWS Organizations. Create the IAM user in your management account with access to all member accounts, and cost data from all accounts is imported automatically.
What is the difference between the Anthropic and Claude providers?
The Anthropic provider connects via the Anthropic Admin API and pulls direct billing data — it shows what Anthropic has charged your account.
The Claude provider uses OpenTelemetry (OTel) to receive telemetry from Claude Code, Cowork, and similar agents running locally — it shows estimated usage costs based on token counts.
Does StackSpend support currency conversion?
Yes. Costs are stored in their original currency and converted to your preferred currency using daily exchange rates. You can set your preferred currency in Settings → Organization.
What is the API and who is it for?
The StackSpend REST API lets you pull cost data, rollups, and anomaly alerts programmatically. It is designed for teams that want to build custom dashboards, integrate spend data into internal tools, or automate reporting.
See the API reference for endpoints and authentication.
