Screpy vs SpeedCurve in 2026: Budget all-in-one monitoring vs enterprise performance benchmarking
One bundles page speed into a $10-a-month audit and rank tracking suite. The other is a $90-a-month specialist platform built by the engineers who helped define web performance culture.
Screpy
SpeedCurve- Screpy bundles page speed with site audits, rank tracking, and uptime monitoring starting at $10 a month. SpeedCurve does performance monitoring only, starting at $90 a month.
- SpeedCurve includes API access on every tier, including the $90 Starter plan. Screpy has no API on any of its three plans.
- SpeedCurve's business impact correlation, connecting LCP and load time to conversion rate, has no equivalent in Screpy's feature set.
- Screpy includes white-label PDF reports from its $30 Pro tier. SpeedCurve does not list white-label reporting as a feature on any plan.
- Both tools offer competitor tracking, but only SpeedCurve documents the methodology: competitor URLs are tested using the same synthetic testing approach applied to your own site.
- SpeedCurve was founded by Steve Souders and Mark Zeman, two of the most recognized names in web performance engineering, and the platform is positioned for teams that treat page speed as a dedicated discipline.
Screpy and SpeedCurve overlap on exactly one line item, page speed monitoring, and diverge everywhere else. Screpy folds Core Web Vitals tracking into a $10-a-month bundle that also covers site audits, rank tracking, and uptime alerts, built for freelancers and small businesses who want one login instead of four subscriptions. SpeedCurve does a single job at a depth Screpy does not attempt: synthetic and real-user performance monitoring with competitive benchmarking against named rivals, business impact correlation that ties load time to conversion rate, and API access on every plan for CI/CD pipeline integration. Picking between them is really a question of scope. If page speed is one item on a longer SEO checklist, Screpy covers it along with everything else for less than a tenth of SpeedCurve's entry price. If page speed is the checklist, SpeedCurve gives a dedicated performance team the benchmarking and API access to prove impact, not just measure it.
The tools at a glance
Screpy
AI-powered SEO platform combining site audits, rank tracking, page speed monitoring, and uptime checks from $10 a month
Screpy treats page speed as one module inside a broader monitoring bundle rather than a specialty in itself. Alongside Lighthouse-based Core Web Vitals scores, the $10-a-month Lite plan includes a technical SEO audit, keyword rank tracking, and uptime alerts, so a solo operator managing several client sites gets four tools worth of coverage under one subscription. The AI layer turns raw audit output into plain-language, prioritized recommendations, which lowers the bar for teams without a performance specialist on staff.
On page speed specifically, Screpy pulls Lighthouse-based lab scores for LCP, FID, and CLS and tracks them over time so you can see whether a deploy helped or hurt. That is useful for a monthly health check, but it is lab data only, no real user monitoring, and there is no way to correlate a speed regression with revenue or conversion loss the way a dedicated performance platform can.
The trade-off shows up in depth and access. No Screpy plan includes API access, so the data stays inside Screpy's own dashboard and exports. For a freelancer checking whether a client site is trending in the right direction, that is rarely a problem. For a team that needs to wire performance budgets into a CI/CD pipeline, it rules Screpy out entirely.

SpeedCurve
Web performance monitoring platform that tracks site speed through synthetic testing and real user monitoring, with competitive benchmarking and business impact correlation.
SpeedCurve was founded by Steve Souders and Mark Zeman, both well known in the web performance field, and the product reflects that pedigree. It combines synthetic testing with real user monitoring in one interface and puts two features front and center that general SEO tools do not attempt: competitive benchmarking against named rival URLs on identical measurement methodology, and business impact correlation that connects metrics like LCP to conversion rate.
That business impact layer is the feature that separates SpeedCurve from most monitoring tools in this category. Once performance data is expressed in terms a non-technical stakeholder can act on, revenue per session, conversion rate, it becomes much easier to justify engineering time on performance work. The API is available on every tier starting at $90, so teams can trigger tests, check budgets, and pull historical data directly from a deployment pipeline.
None of this comes cheap. Pricing starts at $90 for Starter and jumps to $576 for Growth, with Enterprise requiring a custom quote, and there is no free tier. The interface also assumes a level of performance literacy that a general SEO practitioner may not have; SpeedCurve is built for a team whose job is performance, not for someone checking Core Web Vitals as one task among many.

Which should you choose?
ScrepySpeedCurveScrepySpeedCurveScrepySpeedCurveSpeedCurveScrepy and SpeedCurve are not really competing for the same buyer. Screpy is a generalist tool where page speed is one module among audits, rank tracking, and uptime checks, priced for someone who cannot justify four separate subscriptions. SpeedCurve is a specialist tool built for a team whose job is performance, with API access, benchmarking, and business impact data that a generalist platform has no reason to build. The question is not which tool is better, it is whether page speed is a line item on your checklist or the checklist itself.
Bottom line
Start with Screpy at $10 a month if you need broad SEO monitoring on a freelancer or small-business budget and page speed is just one thing you are tracking. Choose SpeedCurve if your team is measured on performance specifically and needs competitive benchmarking, business impact data, and API access to prove that work matters. Do not expect Screpy to replace a dedicated performance platform, and do not pay SpeedCurve prices if all you need is a monthly Core Web Vitals check alongside a basic SEO audit.
Frequently asked questions
Is Screpy a good replacement for SpeedCurve for tracking Core Web Vitals?
Screpy is not a real substitute for SpeedCurve if performance is a dedicated function on your team. Screpy tracks LCP, FID, and CLS using Lighthouse-based lab data only, with no real user monitoring, no business impact correlation, and no API, while SpeedCurve combines synthetic and real user data with both of those features on every plan.
Why does SpeedCurve cost so much more than Screpy?
SpeedCurve's $90 starting price reflects a narrower, deeper product built for performance specialists, with competitive benchmarking, business impact correlation, and API access included from the first tier. Screpy's $10 starting price reflects a broader, shallower bundle that spreads its cost across four functions, audits, rank tracking, uptime, and speed, none of which get SpeedCurve-level depth.
Does Screpy have an API for pulling performance data into a custom dashboard?
No, Screpy does not offer API access on any of its three plans. If you need to pipe Core Web Vitals or audit data into a custom reporting pipeline or CI/CD workflow, SpeedCurve's API, included on every tier from $90 a month, is built for that use case and Screpy is not.
Can SpeedCurve replace an all-in-one tool like Screpy for small business SEO?
SpeedCurve will not replace Screpy for general SEO monitoring because it does not do rank tracking, uptime alerts, or technical site audits at all, it is a performance-only platform. A small business that wants one dashboard covering speed plus the rest of its SEO checklist is better served by Screpy's bundle.
Which tool is better for showing clients that a site speed fix improved conversions?
SpeedCurve is the better choice for that specific case because business impact correlation, connecting metrics like LCP to conversion rate or revenue per session, is a named feature from its Growth tier up. Screpy tracks Core Web Vitals trends over time but has no equivalent way to tie those numbers to business outcomes.
