The short version

  • Each has a real cost: Bitwarden the integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: Bitwarden covers Unlimited password storage, Thanos covers Global query.

Where each one falls short

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

Bitwarden

  • The integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month
  • Free accounts can share vault items with one other Bitwarden user and no more
  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
  • Two-step login accepts up to 10 hardware security keys per account
  • The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month

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
