The short version

  • Each has a real cost: SST primarily optimized for AWS with Cloudflare support; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: SST covers Single config file, Thanos covers Global query.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

SST

  • Managing databases and storage alongside application codenot Thanos
  • Creating staging environments for feature testingnot Thanos

Thanos

  • Querying metrics across many clusters or regions from one placenot SST
  • Retaining metrics for years without local disk growthnot SST
  • Removing the gap that appears when a single Prometheus instance restartsnot SST

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SST

  • Primarily optimized for AWS with Cloudflare support
  • Learning curve for developers unfamiliar with infrastructure concepts
  • Limited documentation for some advanced use cases

Thanos

  • Several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • The compactor is a common source of operational trouble and must not run twice against the same bucket
  • Query latency over object storage is meaningfully higher than local Prometheus
  • Object storage costs and API request charges become real at high volume

Answered from the vendors’ own pages

SST: Is SST free?

Yes, SST is open source and free. You only pay for cloud resources from AWS and other providers.

Source
Thanos: Is Thanos free?

Yes, open source and CNCF-incubating. Costs are the object storage it uses.

SST: What cloud providers does SST support?

SST supports over 150 providers through built-in AWS and Cloudflare components, plus Pulumi and Terraform providers.

Source
Thanos: Does Thanos replace Prometheus?

No. It runs alongside existing Prometheus servers, adding global query, deduplication and long-term storage.

Thanos: Thanos or VictoriaMetrics?

Thanos layers onto Prometheus using object storage and is the more established multi-cluster answer. VictoriaMetrics is a separate store aiming at lower resource use and fewer moving parts.
