komiser

Komiser maps your entire cloud footprint in one place: every resource across AWS, GCP, Azure, and more, with the cost attached. It answers what do we actually have running and what is it costing us, which is harder than it should be once you're spread across accounts and clouds. Free to self-host.

You run it as a single binary or container with read-only credentials, and it builds a dashboard of resources, regions, and spend. Setup is quick, and it's aimed at giving a solo operator or a small team a clear picture without standing up a heavy platform.

One thing to know: Komiser is under the Elastic License 2.0, so it's source-available, not true open source. You can self-host it freely for your own use, you just can't turn around and offer it to others as a hosted service. Solo operators and small teams won't feel that limit at all. Tailwarden, which maintains Komiser, sells the hosted version if you'd rather not run it.

The catch: inventory tools live and die by provider coverage, and the newest services or niche resource types may not show up. It's great for the common resources; verify anything critical against the provider console.
