SpeedCurve review and pricing

Core Web Vitals specialist; Cloudflare-acquired November 2024.

By SpeedCurve Ltd. (Cloudflare, Inc.) · Founded 2013 · Wellington, New Zealand · public

SpeedCurve is the most depth-focused Core Web Vitals and front-end performance product in the category, founded by Mark Zeman with Steve Souders as adviser and acquired by Cloudflare in November 2024 for an undisclosed sum. The product combines synthetic testing (WebPageTest engine) with RUM data, and front-end performance teams cite it as the only standalone-purchasable RUM where CWV waterfall analysis, third-party impact attribution, and design-budget workflows are first-class rather than secondary. The trade-offs: post-acquisition independence is unclear past 2026 as Cloudflare folds capabilities into Cloudflare Observability, pricing tiers are published but skew toward perf-engineering team budgets rather than full-stack observability spend, and infrastructure-monitoring teams will find no logs or APM here.

Best for

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.

Worst for

Buyers needing logs, APM, or full observability (Datadog or New Relic wins), or organizations already paying for bundled RUM via APM platforms.
