Similarweb is a popular tool for checking website traffic and spying on competitors, but it is not cheap. Plans start around $125 a month, and there is no lasting free version, just a short 7-day trial. That is why so many marketers, bloggers, and small business owners are searching for free alternatives to Similarweb that still get the job done without the big price tag. The good news is that several free tools can cover the same core tasks, such as tracking traffic, finding keywords, and studying competitors.
In this guide, we tested six of the best free options in 2026 and checked something most lists skip: which tools can actually see competitor traffic, and which ones only track your own website.
Quick Answer
Similarweb starts around $125 to $199 a month and has no permanent free plan. Below are 6 free alternatives to Similarweb that real marketers use, tested in 2026. The one thing no other list makes clear: which tools can actually see your competitors’ traffic, and which only track sites you own.
Why look for a Similarweb alternative
- Price. Similarweb’s self-serve Competitive Intelligence plan is about $125 a month billed yearly, or $199 month to month. Team and Business plans reach roughly $14,000 to $35,000 a year.
- No real free plan. There is only a 7-day trial (card required, about 15 actions a day) plus a basic no-signup web tool that shows around 5 results per metric.
- Weak accuracy on small sites. Estimates for sites under about 100,000 monthly visits can be off by 50% or more. This is a known limit of all panel-based tools, not just Similarweb.
- Thin SEO execution. Similarweb tells you what competitors get. It does little to help you act on it, so many teams add an SEO tool anyway.

How accurate are free Similarweb alternatives?
Treat every third-party number as directional, never exact. Similarweb, Ubersuggest, Semrush, and Ahrefs all build competitor estimates from panels, clickstream data, and models. They agree more on big sites and disagree a lot on small ones. One real 2026 example: a marketer’s own site showed about 5,100 organic sessions in Google Analytics while a popular tool estimated 88,700, then later dropped its own estimate to 7,000 overnight.
The takeaway: The takeaway: use free estimates to spot trends and compare rivals, then confirm your own numbers in Google Analytics and Search Console. For a competitor you cannot verify, cross-check two tools before you trust a figure.

How to choose the right free Similarweb alternative
- Measuring your own site? Start with Google Analytics and Search Console. Both are free and exact.
- Spying on a competitor? Use Ubersuggest or Semrush’s free tier for search traffic and keywords.
- Hate monthly bills? Ubersuggest’s lifetime license is the cheapest long game.
- Planning content or video? AnswerThePublic gives the real questions to target.
- Want free backlink data? Verify your site in Ahrefs Webmaster Tools.
Most people end up pairing two free tools: one for their own data and one for competitor estimates. That combination covers most of what Similarweb does, at no cost.
Moving off Similarweb: what transfers and what does not
Similarweb has little data you can carry out. On a paid plan you can export charts to CSV or a report, but the free web tool only allows screenshots. There is no historical archive to migrate and no live sync into other tools, so switching is clean. You are not moving data so much as changing where you look.
The real switching cost is workflow, not export. If your team built dashboards or reports around Similarweb’s channel view, rebuild those around your new stack. Free tools give you traffic by channel for your own site (Google Analytics) and search estimates for rivals (Ubersuggest or Semrush). Set both up before you cancel any trial so you do not lose visibility for a week.
Who should stay with Similarweb
- You need full-channel traffic estimates for large competitors, including direct and social, not just search.
- You run investor, market-share, or due-diligence reports where one branded source matters.
- You analyze big sites where panel estimates are more stable and the price is easy to justify.
- You need app-download and audience data alongside web traffic in one place.
Imperial AI Tools verdict
For most people, the best free alternatives to Similarweb are not one tool but two: Google Analytics for exact data on your own site, plus Semrush’s free tier or Ubersuggest for competitor search estimates. That pair covers the core jobs at zero cost.
Our top pick is Google Analytics 4 for its exact, free, first-party data. The runner-up is Semrush, the closest all-round replacement when you also need to study rivals. Pick by the job: own-site truth, or competitor guesswork. Neither should cost you a cent to start.
Frequently Asked Questions
Yes. Similarweb was founded in 2007 by Or Offer in Tel Aviv, Israel, and is incorporated there under Israeli law. It now trades on the New York Stock Exchange as SMWB and runs offices in cities including New York and London, but its roots and a large share of staff remain in Israel.
Only in a limited way. Similarweb has no permanent free plan. You get a basic web tool with about 5 results per metric and no signup, a free Chrome extension, and a 7-day trial that needs a card and caps you at roughly 15 actions a day. For ongoing use you must pay.
Open Google Search Console, click add a property, and enter your domain. Verify ownership using a DNS record, an HTML file, or your Google Analytics tag. Once verified, submit your sitemap so Google can crawl your pages. Data on clicks and keywords starts to appear within a few days.
Ubersuggest is directional, not exact. Its competitor traffic and keyword numbers can differ a lot from real Google data, which is true of all third-party tools. Accuracy is the same across its price tiers, so a higher plan buys more volume, not better precision. Use it for trends, then confirm your own numbers in Analytics.
Go to analytics.google.com and sign in with the Google account linked to your property. Pick the site from the property list to open its reports. The Reports section shows real-time and historical traffic; Acquisition shows where visitors come from. Make sure the GA4 tag is installed on your site first, or no data will show.
