Cost Guard

Cost Guard monitors your cloud infrastructure spending against configurable thresholds and alerts your team before costs spiral out of control. Instead of discovering surprise bills at the end of the month, you get notified the moment spending crosses your budget limits.

How It Works

Cost Guard connects to your cloud service APIs, polls for current usage data on a schedule, and compares metrics against your defined thresholds. When a threshold is breached, TinyOps sends a notification through your preferred channel.

Live Rules

Vercel Budget Alert

Monitors your Vercel month-to-date spend and alerts when it exceeds your configured threshold.

Setting	Default
Metric	Month-to-date spend
Threshold	$50
Trigger	Schedule (9 AM daily)
Notification	Slack

vercel-budget-alert.yaml


name: vercel-budget-alert
trigger:
  type: schedule
  cron: "0 9 * * *"
provider: vercel
condition:
  field: billing.mtd_spend
  operator: gte
  value: 50
action:
  type: notify
  channel: slack
  message: "Vercel MTD spend is ${{billing.mtd_spend}}, exceeding $50 threshold"

Supabase Row Limit

Monitors per-table row counts in your Supabase database and alerts when a table exceeds the configured row limit.

Setting	Default
Metric	Table row count
Threshold	10,000 rows
Trigger	Poll (every 1 hour)
Notification	Email

supabase-row-limit.yaml


name: supabase-row-limit
trigger:
  type: poll
  interval: 1h
provider: supabase
condition:
  field: table.row_count
  operator: gte
  value: 10000
action:
  type: notify
  channel: email
  message: "Table '{{table.name}}' has {{table.row_count}} rows, exceeding 10,000 limit"

Supabase row count checks use the database statistics view for performance. Counts may lag slightly behind real-time values. For exact counts, consider a lower poll interval.
