RUM for Agencies and Consultants 2026
Running a performance practice across multiple client websites needs different RUM economics than running a single internal product. Multi-tenancy, project-based billing, white-label, and hand-off all matter.
Direct answer
What's the best RUM tool for an agency running performance work for multiple clients?
SpeedCurve has the strongest performance-budgets and competitive-benchmarking features for agency work. Catchpoint Expert is the enterprise-tier RUM + synthetic for high-end performance consultancies. For per-client billing, look for vendors that support white-label or sub-account billing, SpeedCurve, Datadog, and Dynatrace all do.
What agencies need that internal teams don't
- Multi-tenancy or multi-account. Need to separate client data, dashboards, and alerts. Sub-account billing helps with project profitability tracking.
- White-label or co-branded dashboards. Some clients want to view performance dashboards under the agency's brand.
- Project-based billing. Many clients pay for the RUM tool as part of an engagement, not as ongoing infrastructure. Need clean billing handoff at engagement end.
- Comparative benchmarking against named competitors. “Your site is 1.8s LCP vs your competitor at 2.4s” is the agency's selling point.
- Hand-off documentation. When the engagement ends, the client should be able to take over the RUM contract without losing data history.
Vendors that fit agency work
- SpeedCurve — performance-budgets and competitive benchmarking are headline features; widely used by performance consultancies.
- Catchpoint Expert — enterprise-grade RUM + synthetic + replay. $11,988/yr per account.
- Datadog RUM — sub-account billing supports multi-client isolation; per-session billing works for short engagements.
- Dynatrace RUM — multi-environment isolation; enterprise-tier features.
- Raygun — multi-project under one account; cheap enough that agencies can absorb the cost across multiple small clients.
Vendors to skip for agency work
- Sentry — strong individual-team tool but multi-client billing is awkward; teams typically use separate Sentry orgs per client which adds operational cost.
- Cloudflare Web Analytics — free, but tied to Cloudflare proxy; hard to use as a portable agency tool across clients on different CDNs.
- Free tiers generally — agencies can't bill clients for free products and lose the “tooling investment” talking point.
Billing models that work
- Per-client annual subscription — agency holds the contract, bills client back with a margin. Works for clients who want a stable retainer.
- Project-based — agency runs RUM during the engagement, hands off to client at end. Works for short engagements (90 days or less).
- Sub-account per client — agency holds master account, each client has a sub-account billed separately. Works at scale (10+ clients).
Hand-off considerations
At engagement end, the client typically needs to either take over the RUM contract or migrate to a different tool. Both have friction:
- Contract takeover — client signs a new contract directly with the vendor. Data history is preserved if the vendor supports account ownership transfer. Many do; some don't.
- Tool migration — client picks a different tool, SDK is swapped, historical data is lost or exported. Budget 2-4 weeks of engineering time.
Pick a vendor whose hand-off path matches the most likely client preference. SpeedCurve, Datadog, and Dynatrace all support account transfer; Sentry technically does but the workflow is less mature.
