The short answer. The six credible SimilarWeb alternatives in 2026 are : Derrick (€9/month, runs inside Google Sheets), BuiltWith ($50/month per tech filter), Wappalyzer ($250/month), Apollo (free tier, then $49 per seat per month), ZoomInfo (~$15,000/year, 3-seat minimum) and HG Insights (~$40,000/year, custom). SimilarWeb itself starts at $199/month for Pro and climbs past $14,000/year for Sales Intelligence, which is the reason most teams start looking. Pick on what you actually need : tech-stack targeting goes to BuiltWith or Wappalyzer, contact data and outbound go to Derrick or Apollo, enterprise IT-spend intelligence goes to HG Insights.
SimilarWeb is the industry-standard web traffic + competitive intelligence platform - 100M+ sites measured for traffic, engagement, marketing channels, and audience overlap. Free tier with limited data, paid plans from $199/mo for Pro and $14K+/yr for Sales Intelligence. Best for marketing teams + sales targeting traffic-defined ICPs ; overkill for general prospecting.
If SimilarWeb isn't fitting (typically because of pricing climbs fast above the $199 entry tier, pricing scale, or stack misalignment), there are 6 credible 2026 alternatives worth shortlisting. This guide ranks them by price, feature depth, and ICP fit so you can shortcut the procurement comparison.
