Best Similarweb Alternatives

Overall Score73/100

Market Signal 84

Similarweb estimates traffic and engagement for websites and apps, so teams can benchmark competitors, study acquisition channels and size markets. Its self-serve AI search packages include one user and three to six months of history, while Web Intelligence, data feeds and API access are sold through sales-led packages. Buyers often look elsewhere when they only need one slice of that data, such as app store estimates, ad creatives, technology adoption or competitor messaging. The Similarweb competitors below each cover one of those slices.

Free Similarweb alternatives

If you're after free sites like Similarweb, expect trade-offs. None of the tools here gives away full traffic estimates, but three have a free starting point.

Semrush has a free plan with 10 reports a day across its main tools and one demo project, with no card needed. Its Traffic & Market toolkit, the part that compares competitor visits, is a paid add-on.

BuiltWith is free for looking up the technology behind one site at a time. Adbeat has a free Basic plan for browsing competitors' display ads, though it doesn't publish that plan's limits.

Similarweb itself shows a high-level sample of any site's traffic for free on similarweb.com. For a quick check on one competitor, that's often all you need.

Frequently Asked Questions

Which Similarweb alternative also estimates website traffic?⌄

Among these options, Semrush is the one that estimates competitor traffic. Its Traffic Analytics report shows visits, unique visitors, channels and top pages, Market Explorer maps a niche and EyeOn tracks competitors' new pages and ads. It needs the separate Traffic & Market subscription, and free users only see sample domains.

What should app publishers use instead of Similarweb?⌄

Sensor Tower's Store Intelligence focuses on mobile apps, estimating downloads, revenue, active users and store rankings across the App Store and Google Play, broken down by country, category and platform. It also supports ASO keyword research. Similarweb sells App Intelligence as a separate product, so compare the two on the markets and categories you track.

Does Similarweb have a free trial?⌄

Yes. Similarweb's self-serve AI search packages each come with a free trial, and its support team can move you between product trials. There is no free plan; the free data on similarweb.com is a high-level sample. Larger Web Intelligence packages with longer history, data feeds and API access are arranged through sales.
