Open Source by Capped
Small, scriptable guardrails for cron, CI, and custom workflows.
Capped gives you two paths. Use the extension if you want the simplest setup. Use our open-source tools if you want something scriptable, composable, and easy to drop into automation.
Developer path
Not another dashboard. Just small tools that do one job cleanly.
Choose the opinionated tool when the use case is known. Choose the primitive when you want to plug threshold alerts into your own workflow.
Spend-specific tool
capped-cost
Track OpenAI and Anthropic spend from cron, CI, or your own scripts.
Generic alert primitive
threshold-hook
Send threshold-based alerts for any numeric value without alert spam.
