Observatorium vs Thanos
Both stand on kubernetes monitoring. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APISelf-hosted
Observatorium brings several observability projects together behind shared tenancy and access controls. It provides strong metrics and log foundations, but tracing and project documentation are still developing.

Thanos provides cross-cluster querying and long-term storage for Prometheus environments. Its security limitations around local metrics and HTTP APIs should be weighed when planning a deployment.
