Where each one falls short

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

StackBlitz

  • Specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.
  • Browser-based execution via WebContainers has limits on which native/binary dependencies can run compared to a real server-backed environment.
  • Heavy or resource-intensive workloads may be constrained by the end user's own browser and machine resources.

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

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

StackBlitz: What does the Teams plan add?

Teams lets GitHub organizations add free or paid members; paid members get access to private collections and repositories, with permissions mirrored from GitHub-owned repos.

Source
Thanos: Does Thanos replace Prometheus?

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

StackBlitz: Is there an Enterprise option?

Yes, custom Enterprise plans are available and require contacting StackBlitz directly.

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.
