How does StackSpend handle Claude Spend Alerts?
StackSpend delivers Claude spend alerts from OpenTelemetry usage across Claude Code, Cowork, and Office agents. Set a budget on estimated Claude cost, get pace-to-forecast warnings, and receive same-day anomaly alerts when a workflow spikes — via Slack, email, or webhook.
How does it work in practice?
- 01
Set a budget on estimated Claude cost and let pace-to-forecast warn you.

- 03
Alerts arrive via Slack, email, or webhook.
What makes this work?
Price the tools that have no billing API.
Claude Code, Cowork and Office agents emit OpenTelemetry usage straight to a StackSpend endpoint — nothing to install, no credentials stored. Usage is priced per model, user and session as a token-based estimate, and labelled as one.
How it worksCatch 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 worksOne message each morning. Nobody opens a billing portal.
