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.
- 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.
- Sentry (Per Usage) — Sentry bills on usage — $26/mo Team (50K errors + 5GB logs + 5M spans) + $0.50/GB overage on top of a paid plan starting at $29/mo. The plan includes an allowance; anything beyond it is metered.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

What each is best for
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.
Sentry is worth it if… Sentry is ideal for dev teams who want fast error monitoring across the full stack without an observability procurement conversation. Best if bugs/errors are the primary pain point and you'll add tracing/replay/profiling as you grow.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
