Sentry Performance review and pricing

Performance and Web Vitals layered on Sentry error tracking.

By Functional Software, Inc. · Founded 2012 · San Francisco, CA · private

Sentry Performance is the RUM and transaction-tracing module of Sentry, layered on top of the best-in-class Sentry error-tracking core. The product captures Core Web Vitals, transaction spans, and JavaScript errors with native links to session replay, and is sold within Sentry's published per-event and per-replay pricing rather than as a separate platform. The defining shape is hybrid: Sentry is closer to an "errors plus session replay plus light RUM" product than a pure CWV specialist. Best-fit is SaaS engineering teams who already use Sentry for errors and want web vitals data in the same pane. The trade-offs: dedicated perf-team workflows are lighter than SpeedCurve, no infrastructure or logs, and session replay quota economics deserve scrutiny.

Best for

SaaS and product engineering teams (10-2,000 employees) who use Sentry for error tracking and want web vitals plus session replay layered on the same platform.

Worst for

Performance engineering teams needing SpeedCurve-depth CWV analysis, or buyers needing full observability (Datadog or New Relic wins).
