How pricing works

These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.

  • Clerk (Unknown model) — Clerk bills on a fixed plan from $25/mo, so the listed price is what you pay regardless of volume.
  • OpenObserve (Per Usage) — OpenObserve bills purely on usage — $0.50/GB ingest + $0.01/GB query (30% off annual, no per-seat fees). There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.

Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

Clerk is worth it if… js / React apps who want user management + social login + billing + orgs shipped in an afternoon — not weeks. Free tier covers up to 10K MAUs; Pro adds SSO, advanced features, and higher limits.

OpenObserve is worth it if… OpenObserve is ideal for teams migrating off Datadog, Splunk, or New Relic who want radically transparent pay-per-GB pricing with no seat fees. Best if your telemetry cost is dominated by log and metric volume rather than user count.

Bottom line: Similar positioning, closer to a preference call than a strategic one.
