Cost analysis
Monthly cost delta on every Terraform PR — before it merges.
Powered by Infracost
DriftGuard runs Infracost on every Terraform plan JSON and reports the monthly cost delta per resource. If a PR would add €500/month of EC2 instances, that appears in the PR comment before anyone merges.
Thresholds
# .github/driftguard.yml cost: threshold_monthly_usd: 500 # warn above $500/mo delta block_above: 5000 # block merge above $5000/mo delta
Currency
Cost is reported in the currency configured in your workspace settings. Exchange rates are fetched daily. Supported: USD, EUR, GBP, BRL.
