LeftSize vs Vantage
Vantage is a cost visibility platform: it brings the spend of AWS, Azure, Google Cloud and 40+ other providers into reports, dashboards and budgets, with cost recommendations and automated AWS Savings Plans. LeftSize looks at the resources themselves and turns idle resources, upcoming retirements and governance gaps into GitHub or Jira issues for the team that owns them. Vantage answers where the money goes; LeftSize hands engineers the fixes.

Where Vantage is the better choice
- Shows total spend, trends and allocation per team, product or tag, which LeftSize does not do.
- Covers Google Cloud, Kubernetes and dozens of SaaS and data providers, not only AWS, Azure and Cloudflare.
- Budgets, forecasts and automated AWS Savings Plans purchasing.
What LeftSize adds
- Findings land as issues in the GitHub repository or Jira project of the team that owns the resources, with a fix script, instead of in a separate console.
- Tracks service retirements and end-of-support deadlines on your actual resources, months before they cost money or break.
- Security and governance checks on the same resources.
- Needs no access to billing data: read-only access to the resources is enough.
Using them together
Use Vantage to see and allocate where cloud money goes, and LeftSize to turn the waste and retirements in your AWS, Azure and Cloudflare accounts into issues engineers fix.
