Where each one falls short

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

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

You.com

  • Pricing tiers beyond the pay-as-you-go table are not published and require contacting sales for volume discounts.
  • Finance Research API is priced significantly higher than the other endpoints, at $110 per 1,000 calls.
  • No self-serve dashboard details are published for managing enterprise zero-retention settings.
