RUM Cost 2026: $0.50 to $5.65 per 1K Sessions, 5 Vendors Quote-Only

The 3-card answer band

Most procurement decisions on Real User Monitoring fall into three clear bands by traffic volume. The card most users want is the middle one, 100K to 1M sessions per month, where the cheapest published per-session rate (Sentry at $0.50/1K) and Datadog's roughly $3.15/1K investigate-everything rate (before its separate replay add-on) produce a 6x-plus spread on the same workload. The lowest band, under 100K sessions per month, is dominated by free tiers from Cloudflare, Sentry, Fullstory, and Raygun. The highest band, above 1M sessions per month, is where vendors stop publishing prices and switch to enterprise quote-only pricing. The matrix below lists each tier with its actual price.

What Real User Monitoring measures

RUM is a category of frontend observability tool that runs a small JavaScript snippet in the visitor's browser. The snippet captures three buckets of telemetry: timing data (page load, Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift, time-to-first-byte), error data (uncaught exceptions, network failures, console errors), and session data (clicks, scrolls, page-to-page navigation, and in many tools a full visual replay of the session). All of this is sent to the vendor's collection endpoint, processed, and surfaced as dashboards, alerts, and replay players.

RUM differs from synthetic monitoring (which runs scripted browser sessions on a schedule from controlled locations) by capturing only real user behaviour. It differs from Application Performance Monitoring (APM) by sitting in the browser, not the backend application server. It differs from log analytics by being event-driven rather than line-by-line. And it differs from session replay-only tools (Hotjar, FullStory's legacy product) by including performance metrics alongside the replay.

The pricing model that dominates RUM is per-session or per-pageview, because the vendor's cost scales with the volume of beacons received from end-user browsers. Vendors that ingest into a broader observability platform (New Relic, Elastic, Grafana Cloud) charge per-GB of data ingested across all telemetry. Vendors that bundle RUM into a wider enterprise observability suite (Splunk, Cisco AppDynamics, Akamai mPulse) tend toward quote-only enterprise pricing.

Why per-session prices vary 6x or more

On the same workload, say, 1 million sessions per month investigated in full with 30-day retention, Sentry's base rate works out to about $500/month while Datadog's Measure-plus-Investigate meter is about $3,150/month before its separate replay add-on. That 6x-plus spread is real, and it has four drivers.

• Add-on session replay. Datadog, Dynatrace and Sentry all charge for session replay separately (Datadog $2.50/1K, Dynatrace $2.25/1K, Sentry $3.75/1K). LogRocket treats replay as the entire product. Charging separately means you only pay replay on the sessions you actually record, so dialling replay coverage down is a direct cost lever.
• Retention. 30 days is the default. 90 days adds 20-30% to most vendors' bills. 13 months (Fullstory, some enterprise tiers) adds 50% or more. Sampling matters too, many enterprise RUM contracts default to 10% sampling and surcharge for 100% capture.
• Pricing-model collision. A vendor charging $0.40/GB of data ingest (New Relic) will look cheap for low-volume RUM but expensive once it bundles APM, logs, and infrastructure into the same ingest meter. A vendor charging per-session (Datadog, Dynatrace) is predictable on a single product line but doesn't scale discount across the wider stack.
• Annual commit discount. Most vendors offer 15-25% off annual prepayment. SpeedCurve publishes 20%, Sentry 17%, LogRocket 17%. Datadog discounts annual commit but doesn't publish the percentage. Quote-only vendors negotiate annual discount as part of the contract.

The five vendors that won't quote a price

Akamai mPulse, Splunk RUM (within Splunk Observability Cloud), Pingdom RUM, Fullstory's paid tiers, and Catchpoint's enterprise tier all require a sales call to learn the price. We don't fabricate numbers for them. We list them in the matrix above with a Quote Only badge and link to their contact pages. See the quote-only vendors deep-dive for the operational consequences of vendor opacity, chiefly, that you cannot run a procurement against them in less than 4-6 weeks, and you cannot benchmark them against published rates without first signing an NDA.
