Zombiecost hunts for AWS’s billing undead
A free, read-only CLI scans AWS accounts for resources that appear idle or unused and estimates their monthly cost.
- For
- AWS operators tracking idle or orphaned resources
- Worth noticing
- It skips resources younger than three days and labels S3 read activity unknown because the relevant request metrics cost extra.
Field notes
The page shows a pip install command followed by a run using an AWS profile, then a table of findings with region, resource, reason, and estimated monthly cost. Its stated safeguards include skipping resources younger than three days and describing S3 read activity as unknown, since those reads are not visible without paid request metrics. The author says the CLI sends only AWS API calls using the user's credentials; hosted weekly scans and Slack alerts are framed as a possible next step.
