Website Performance Monitoring and Core Web Vitals
Managed synthetic and real user monitoring, Core Web Vitals history, Lighthouse audits, performance alerts, and deployment regression analysis. Plans from $45/month.
A single PageSpeed score cannot show when a release slowed your site or which visitors are affected. Continuous measurements connect changes in loading, responsiveness, layout stability, scripts, and third-party resources to a timeline your team can investigate.
EXPECTED OUTCOMES
What the engagement is designed to achieve
A historical baseline for LCP, INP, CLS, and page performance
Alerts against agreed performance budgets with accountable owners
Before-and-after evidence for releases and optimization work
Prioritized findings tied to user experience and affected pages
DELIVERABLES

Synthetic browser checks for agreed URLs, device profiles, and locations
Real User Monitoring setup with web-vitals, sampling, and privacy review
Core Web Vitals trends: LCP, INP, and CLS with field and lab data separated
Lighthouse performance audits and resource waterfall analysis
Regression comparisons annotated with deployment events
JavaScript error and script-impact diagnostics within the agreed scope
Third-party resource analysis for ads, analytics, and external scripts
Competitive benchmarks using comparable public-page test conditions
Performance budgets and alert routing

ENGAGEMENT OPTIONS
Choose the scope that fits your team
Monthly plans and implementation options are scoped before work begins. Coverage, allowances, setup, taxes, and additional work are confirmed in a tailored proposal.
Starter
From $45 / month
Focused monitoring for a small website, with coverage confirmed before activation.
Starter begins at $45 USD per month and Growth at $288 USD per month. Enterprise is quoted individually. These starting prices are 50% below the published SpeedCurve Starter ($90) and Growth ($576) starting prices checked on October 9, 2026; this is a price comparison, not a claim of identical allowances or features. Taxes, setup, infrastructure, and additional implementation are confirmed in the proposal. URLs, test frequency, RUM volume, retention, and support determine the final price.
Is this a self-service SaaS dashboard?
This page offers a managed service with onboarding by consultation. It does not provide an instant monitoring account, checkout, or a live customer dashboard. Collection, access, reports, and integrations are configured after the scope is accepted.
How are synthetic monitoring and RUM different?
Synthetic tests repeat a controlled browser journey and help reproduce changes. RUM records supported performance metrics from actual visitors and reflects their devices and networks. Synthetic Lighthouse tests do not measure field INP; field and lab results are reported separately.
What access does Real User Monitoring require?
RUM requires approval to install a collection snippet on your website. We agree sampling, collected fields, retention, consent requirements, and access controls before installation; personal data collection is not assumed.
Does monitoring include unlimited optimization or guarantee good Core Web Vitals?
No. Monitoring provides evidence and recommendations. Remediation, custom development, support response times, and test capacity are bounded by the agreed scope. Results depend on the application, traffic, hosting, and third-party resources.
