Is Similarweb Free? What You Get for $0 in 2026
Paul VengeonsCo-Founder & SEO ConsultantIn short
Partly. Similarweb's Website Traffic Checker gives 3 free searches a day with no login, and its extension is free. The full platform has a 7-day trial with a card charged at the end, then costs at least $125 a month billed yearly ($199 monthly).
A traffic estimate shows who is winning, not what to do on your site. ChatSEO compares you with your competitors and tells you which pages to work on first.
Summarize this blog post with:
Which Similarweb option is for you?
Answer 4 questions: free checker, extension, trial or paid
π¬ How I checked what Similarweb gives for free
I tested Similarweb's free Website Traffic Checker and its browser extension, then read its trial terms and its pricing page. Every limit and price below was checked on Similarweb's official pages on October 30, 2026. ChatSEO appears near the end because it is the tool I co-founded: it is paid, with a trial, and I say so.
My take after years of SEO for clients: free Similarweb is a good first look at a competitor and a poor way to measure your own site. It estimates traffic from a panel of users; your own analytics measure it.
π Is Similarweb free? The answer at a glance
Partly: Similarweb has free tools with no login, a 7-day trial, and paid plans from $125 a month. There is no permanent free plan of the platform itself.
| Option | Price | What you get | The catch |
|---|---|---|---|
| Website Traffic Checker | $0, no login | Last month's ranks and engagement, 3 months of visits | 3 searches a day |
| Similarweb extension | $0, no account | The same estimates on every site you visit | Partial data on small sites |
| 7-day free trial | $0 for 7 days | The full platform | Card required, charged on day 8 |
| Competitive Intelligence | $125/month billed yearly, or $199 monthly | Any site, 3 months of history, 1 user | No free version |
π The 2 free ways to use Similarweb
1. The Website Traffic Checker: 3 free searches a day
Type any domain on similarweb.com and you get last month's traffic estimate for free, with no account, up to 3 searches a day. For semrush.com in September 2026, the free page showed the global, country and category ranks, the bounce rate, pages per visit, visit duration, total visits over the last 3 months, the top countries, the top keywords, the top competitors and the audience's age and gender.
What stays locked is the detail you would act on. Only the top 3 marketing channels show, with a percentage on the first one only; the referral sites, the full country list, the competitor traffic numbers, exports and the comparison of up to 5 sites all ask you to start a trial. It is enough to know roughly how big a competitor is, not where its traffic comes from.
2. The Similarweb extension: the same estimate on every site you visit
The Similarweb extension is free, needs no account and works on Chrome, Edge, Firefox and Opera. One click on any site shows its monthly visits, bounce rate, pages per session, visit duration, its global, country and category ranks, its traffic sources and countries, its top keywords with estimated clicks and CPC, and even its AI chatbot traffic and top prompts.
It is the best free Similarweb option for a quick look while you browse. Similarweb itself warns that "very small websites with limited traffic may return partial data", and history and advanced filters need a paid plan. Our free Similarweb alternative guide lists other free ways to estimate a competitor's traffic.
πΈ The Similarweb free trial, and what it costs after
Similarweb's free trial lasts 7 days and is tied to a subscription: the card you sign up with is charged automatically when the trial ends. Cancel before the end and you pay nothing. Its help center adds two traps: a Gmail address only works through "Sign up with Google", and an email already used on a Similarweb account cannot start a new trial.
After the trial, Similarweb's Web Intelligence plans start at $125 a month billed yearly, or $199 a month billed monthly. That entry plan, Competitive Intelligence, gives 1 user and 3 months of history. Competitive Intel with SEO and AEO costs $333 a month billed yearly or $399 monthly, with 6 months of history, and the plan with ads intelligence on top costs $542 or $649. Businesses get custom pricing, with up to 37 months of data. Our Semrush vs SimilarWeb comparison shows what you get for that money against an SEO suite.
There is no free Similarweb API either. The API is sold within custom business packages or as a standalone product, through the sales team.

π For your own site: free tools that measure instead of estimating
Google Search Console
For your own site, Google Search Console replaces Similarweb's SEO numbers with real ones, for free. It gives the real clicks, impressions and positions of every Google query, with 16 months of history, where Similarweb shows an estimate.
Read a position only with an exact page and an exact query as filters: the site-wide average mixes thousands of queries. Your Search Console clicks on the pages that sell are the SEO number to watch.
Google Analytics 4
Google Analytics 4 measures every visit to your site, from every channel, for free. It tells you which sources bring visitors and which ones convert, which is the question Similarweb answers about your competitors with estimates.
The catch is the one that applies to every analytics tool: it only works on a site where you installed it, so it never replaces Similarweb on a competitor.
ChatSEO: best for turning competitor data into SEO priorities
ChatSEO is the tool I co-founded, and it is not free: you get a 7-day trial with 30 credits, then plans start at β¬29 a month, or β¬23 a month billed annually. The card is asked at signup and charged on day 7 unless you cancel, with a reminder 3 days before.
It answers the question a traffic estimate leaves open: what to do about it on your own site. It compares your site with your competitors on live keyword and backlink data, reads your Search Console, and returns the pages to work on first. Do not pick it for market-wide traffic shares, app data or ad intelligence: Similarweb does that, and ChatSEO is an SEO tool.

β οΈ How far can you trust free Similarweb numbers?
Similarweb's traffic figures are estimates, not measurements. Use them to compare sites with each other, never as the real traffic of one site.
- Small sites are the weak spot: Similarweb says itself that sites with little traffic may return partial data.
- Last month only on the free page: no trend beyond the 3-month visit total.
- Same panel, same bias for everyone: two competitors read on the same tool compare fairly, even when both numbers are off.

Who should not pay for Similarweb: a small business that only wants to grow its own Google traffic. $125 a month buys market estimates, not a plan for your pages. Our Similarweb alternatives guide compares cheaper paid tools, and our page on whether Ahrefs is free covers the other big name.
