Cloud cost optimization tools

Every kind of tool that touches the cloud bill, by name: what each one does, whether it acts on its own, recommends or reports, and where it runs. Checked on each company’s own pages, 19 October 2026.

Tools in the market

Four groups. Coral and Amoeba are marked in theirs.

Tools that reduce what Kubernetes costs, from those that act on the cluster on their own to the open-source building blocks.
