Quick Verdict
You're looking at two completely different approaches to SEO intelligence. Similarweb is a heavyweight digital intelligence platform that tracks traffic for millions of websites — think competitor research on steroids. Screpy takes the opposite approach: it's a lightweight monitoring tool focused on keeping your own website healthy through uptime checks, speed monitoring, and basic rank tracking.
The core difference comes down to scope versus simplicity. Similarweb analyzes external data about any website on the internet, while Screpy focuses entirely on monitoring your own properties with straightforward alerts and dashboards.

Feature Comparison
Similarweb's strength lies in competitive intelligence features you can't get elsewhere. Their traffic estimation covers desktop and mobile visits, referral sources, and audience demographics for any domain. You can benchmark your site against competitors, discover their top-performing pages, and analyze market share within specific industries. The platform also includes ad intelligence, showing you which display and search ads competitors are running. Screpy operates in a different universe entirely. It monitors page speed using Google's Core Web Vitals, tracks keyword rankings, and sends uptime alerts when your site goes down. The tool includes basic SEO auditing with recommendations for technical fixes, but nothing approaching Similarweb's market intelligence capabilities. What Screpy lacks in breadth, it makes up for in focused execution — its speed monitoring updates every hour, and the interface shows everything on a single dashboard.
Pricing Comparison
The pricing gap is massive and tells you everything about target audiences. Similarweb starts at $149/month for their Starter plan, which includes basic website analysis for 100 websites and limited historical data. Their Professional plans run into the thousands monthly for agencies and enterprises needing deeper data access. Screpy costs $12/month for monitoring up to 10 websites with unlimited keyword tracking and daily reports. Even their highest tier hits just $99/month, making it roughly one-tenth the cost of Similarweb's entry point. Both offer free tiers, but Similarweb's free version only provides five searches per month while Screpy's free plan monitors one website indefinitely.
Best For
Similarweb makes sense when you need external intelligence about competitors or market opportunities. If you're researching acquisition targets, analyzing competitor traffic sources, or presenting market analysis to stakeholders, the traffic estimates and audience insights justify the premium cost. Digital agencies and enterprise marketing teams get the most value from Similarweb's breadth of data. Screpy works better for small businesses and solo practitioners focused on keeping their existing websites running smoothly. The tool excels at catching technical issues before they hurt rankings — I've caught server outages within minutes using their uptime monitoring. If you manage a handful of sites and want simple alerts without complexity, Screpy delivers exactly what you need.
The Verdict
Pick Screpy unless you specifically need competitive intelligence data. The $12/month price point makes it accessible for monitoring essential website health metrics, while Similarweb's $149 minimum only makes financial sense if competitor research is core to your business model. Start with Screpy's free plan to monitor one website and upgrade when you need more properties tracked.
Our verdict
For features, similarweb leads. On a budget, go with screpy.
