If you’re evaluating Sentry Performance for real user monitoring (rum) software, the three strongest independent alternatives in our editorial ranking are Datadog RUM, New Relic Browser, SpeedCurve. Each has a different best-fit buyer — the right choice depends on team size and workflow, not on which has the loudest review-site presence.
Why Sentry Performance sometimes isn’t the right pick: Performance engineering teams needing SpeedCurve-depth CWV analysis, or buyers needing full observability (Datadog or New Relic wins). See full “worst for” verdict →
9 Sentry Performance alternatives
| Rank | Product | Best for | Target size | Pricing |
|---|---|---|---|---|
| #1 | Datadog RUM | Mid-market and enterprise teams (200-10,000 employees) already on Datadog observability who want RUM in the same pane as APM, logs, and synthetics. | 200–100,000+ | ● Transparent |
| #2 | New Relic Browser | Cost-conscious mid-market and enterprise teams (100-10,000 employees) already on New Relic who want RUM bundled into existing observability spend. | 50–10,000+ | ● Transparent |
| #3 | SpeedCurve | Performance engineering teams (often inside ecommerce, media, or large SaaS) where Core Web Vitals depth, third-party impact attribution, and performance-budget workflows justify a standalone RUM purchase. | 20–5,000 | ● Transparent |
| #4 | Akamai mPulse | Akamai delivery and security customers (large ecommerce, media, financial services) wanting RUM bundled with their existing CDN contract. | 500–100,000+ | ○ Quote-only |

Which alternative for which buyer
Datadog RUM
Broadest enterprise RUM, bundled with Datadog observability.
Mid-market and enterprise teams (200-10,000 employees) already on Datadog observability who want RUM in the same pane as APM, logs, and synthetics.
Standalone RUM buyers not on the Datadog platform, cost-sensitive teams (New Relic Browser bundled is cheaper), or perf-engineering teams wanting Core Web Vitals waterfall depth (SpeedCurve better).
New Relic Browser
RUM bundled in New Relic ingestion-based pricing.
Cost-conscious mid-market and enterprise teams (100-10,000 employees) already on New Relic who want RUM bundled into existing observability spend.
Buyers wanting the deepest Core Web Vitals workflow (SpeedCurve wins), or teams not already on New Relic where the per-GB model offers no leverage.
SpeedCurve
Core Web Vitals specialist; Cloudflare-acquired November 2024.
Performance engineering teams (often inside ecommerce, media, or large SaaS) where Core Web Vitals depth, third-party impact attribution, and performance-budget workflows justify a standalone RUM purchase.
Buyers needing logs, APM, or full observability (Datadog or New Relic wins), or organizations already paying for bundled RUM via APM platforms.
Akamai mPulse
Akamai-bundled RUM with CDN edge integration (Soasta origin).
Akamai delivery and security customers (large ecommerce, media, financial services) wanting RUM bundled with their existing CDN contract.
Buyers not on Akamai delivery, perf-team workflows needing SpeedCurve-depth CWV analysis, or modern cloud-native teams on Cloudflare or Fastly.
Catchpoint RUM
RUM bundled into Catchpoint synthetic and IPM platform.
Enterprises (500-50,000 employees) with global delivery concerns already on Catchpoint synthetic and last-mile network monitoring.
Standalone RUM buyers not on Catchpoint, performance engineering teams wanting SpeedCurve-depth CWV, or cost-sensitive mid-market.
Dynatrace Real User Monitoring
RUM bundled into Dynatrace AI-driven observability.
Enterprise SRE and Digital Experience teams (500+ employees) already on Dynatrace observability who want AI-driven correlation between RUM data and backend traces.
Mid-market under 500 employees, standalone RUM buyers, or anyone wanting transparent pricing or a CWV-focused perf-team workflow.
