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.
- 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.
- Splunk Observability Cloud (Per Usage) — Splunk Observability Cloud bills purely on usage — Quote-based via sales — Entity, Ingest, or Workload pricing models. 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.
Sentry is the leading error monitoring and application observability platform for developers. Developer $0 (5K errors, 1 user); Team $26/mo (50K errors, unlimited users, integrations); Business $80/mo (unlimited dashboards, anomaly detection, SAML/SCIM); Enterprise custom. Event-based pricing across errors, tracing, session replay, logs, profiling, metrics with pay-as-you-go beyond quotas. Seer AI debugging agent available as add-on.
Splunk Observability Cloud is Cisco-owned enterprise observability with three quote-based pricing models: Entity (per-host, predictable), Ingest (per data volume, unlimited searches), and Workload (aligned to search patterns). Includes Infrastructure Monitoring, APM, Digital Experience Analytics, Log Observer, and IT Service Intelligence in one platform. No public list prices — all deals go through sales. 14-day free trial available. Acquired by Cisco in 2024.

What each is best for
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.
Splunk Observability Cloud is worth it if… Splunk Observability Cloud is ideal for large enterprises already running Splunk for security who want unified security + observability data in one platform. Best if you can absorb quote-based procurement and have Cisco as a strategic vendor.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
