What is SimilarWeb? SimilarWeb is a digital intelligence platform that provides website traffic and engagement analytics. It's been the go-to SimilarWeb traffic checker for marketers since 2007. But in 2026, its free tier has become severely limited—capped at just 5 results per month with mandatory sign-up.
If you're searching for a SimilarWeb free alternative that gives unlimited traffic checks without a paywall, here's how SiteWorthIt compares head-to-head.
Feature-by-Feature Comparison

Where SimilarWeb Still Wins
To be fair, SimilarWeb excels in areas that matter for enterprise marketing teams:
- Traffic source granularity — detailed breakdown of direct, search, social, referral, email, and paid traffic
- Geographic distribution — traffic by country with percentage breakdowns
- Industry benchmarks — category-level comparisons (paid feature)
- App analytics — mobile app download and engagement data
However, most of these features require SimilarWeb's paid plans starting at $149/month. The free SimilarWeb traffic checker gives you a taste, but the 5 results/month cap makes it impractical for daily use.

- No sign-up wall — start checking traffic immediately
- Revenue estimation — see estimated earnings for any website
- Creator analytics — YouTube, Twitch, and TikTok earnings data
- Free website comparisons — compare any two domains side-by-side
- Global rank checker — Alexa-style rankings powered by Cloudflare Radar
- Google Analytics connection — verify estimates with real data in the free dashboard
SimilarWeb Pricing in 2026

- Free: 5 results/month, basic metrics only

For individuals, bloggers, and small businesses, these prices are prohibitive. That's exactly why free alternatives like SiteWorthIt have grown rapidly.
