Best Similarweb Alternatives in 2026
⭐ What Similarweb is strongest at
Estimating the traffic, channels and audience of websites you do not own. Nothing below does that as well, and most do not attempt it.
If that is not what you actually need, the alternatives below are the better buy. If it is, read our Similarweb review first, because the tools here replace its SEO and AI-visibility modules, not its traffic model.
Compare the top SEO and AI-search visibility tools.
Alternatives
Looking for a Similarweb alternative? Below are 7 tools from the same SEO category, compared against Similarweb for feature fit, pricing tiers and primary use cases.
Every option below has a full ToolChase review, and every price was read from that vendor's own pricing page and matches the figure on its review. Similarweb itself starts at $125/mo billed annually ($199 monthly) for a single seat, and its most popular plan is $333/mo billed annually ($399 monthly).
Why look for Similarweb alternatives?
Four reasons come up again and again. Every Similarweb self-service plan is one seat, and no second-seat price is published. History is 3 or 6 months unless you buy an enterprise package. The platform API, MCP and data feeds are all sales-gated. And as a pure SEO tool, the $333 plan is matched or beaten on depth and price by the specialists below. If you bought Similarweb for competitor traffic, none of that matters much. If you bought it for keyword research or AI-visibility tracking, all of it does.
How they compare to Similarweb
Each alternative wins on a different dimension. Every price below was read from the vendor's own page and matches that tool's review on this site.
Semrush 4.5/5
Best for the widest all-in-one SEO and marketing suite.
SEO $139/mo ($117.33/mo billed annually), Starter $199/mo, Pro+ $299/mo, Advanced $549/mo, with AI search tracking included at every paid tier and a very limited free account. Against Similarweb you lose the third-party traffic and audience layer, but you get far more keyword, rank-tracking and site-audit depth per dollar, and the $139 entry plan undercuts Similarweb's $333 SEO bundle by a wide margin. Pick Semrush when the job is producing and ranking content rather than sizing a market.
Ahrefs 4.6/5
Best for backlink depth and a genuinely free tier.
Ahrefs Free is $0 for your own verified site, Starter is $29/mo (monthly only), Lite is $129/mo ($108/mo billed annually), Standard $249/mo, Advanced $449/mo with 5 seats. Ahrefs is the tool to pick when data depth beats platform breadth: its backlink index is the reference point, and Brand Radar covers AI visibility. It also solves Similarweb's biggest structural complaint, since Advanced ships five seats where every Similarweb self-service plan ships one. What it does not do is estimate a competitor's total traffic and channel mix the way Similarweb does.
SE Ranking 4.4/5
Best for SEO plus AI visibility with API and MCP on every plan.
Core $129/mo ($103.20/mo billed annually) with 2,000 tracked keywords, 100 AI prompts a day across five engines and 25,000 API credits; Growth $279/mo ($223.20/mo annually) with 3 seats and all-time history. SE Ranking gives you the two things Similarweb withholds from self-service buyers, API and MCP access and more than one seat, at a third of the price of Similarweb's $333 bundle. Its AI Competitor Research covers domains rather than modelled traffic, so it is a substitute for the SEO and AEO half of Similarweb, not the market-sizing half.
Moz 4.2/5
Best for a gentler learning curve at a low entry price.
Starter $49/mo ($39/mo billed annually), Standard $99/mo ($79 annually), Medium $179/mo ($143 annually) with 2 users and an AI Visibility beta, Large $299/mo ($239 annually) with 3 users, plus a 7-day trial that takes a card. Moz is the easiest of these to learn and the cheapest way into rank tracking and Domain Authority. It has no competitor traffic estimation, so it replaces Similarweb only for a team that bought it for SEO and found the traffic layer unused.
Serpstat 4.3/5
Best for undercutting everything else on price.
Individual $69/mo, Team $129/mo with 3 users, API, AI tools and a ChatGPT and Claude MCP integration, Team x2 $209/mo with 6 users, Agency $499/mo with 30 users; annual billing takes the four tiers to $50, $100, $169 and $410 a month. Serpstat's Team plan gives three seats and an API for less than Similarweb's single-seat entry plan on monthly billing. The trade is data breadth: no traffic estimation, no audience overlap, and a smaller index than Semrush or Ahrefs.
Profound 4.0/5
Best when AI search visibility is the whole job.
Starter $99/mo for ChatGPT tracking with 50 prompts, Growth $399/mo for three answer engines, 100 prompts and 3 seats, Enterprise custom with up to nine engines; annual billing is advertised as two months free. Profound is a dedicated AEO specialist, so it goes deeper on prompts, agents and per-engine analysis than Similarweb's bundled module. Similarweb's own AEO Intelligence plan is $99 a month billed annually ($129 monthly) with 150 tracked prompts, so compare the two on engine coverage, prompt counts and seats rather than headline price.
Otterly.ai 4.4/5
Best for cheap AI-visibility monitoring with a no-card trial.
Lite $29/mo ($25/mo billed annually) with 15 prompts, Standard $189/mo ($160 annually) with 100 prompts, Premium $489/mo ($422 annually) with 400 prompts, Enterprise custom, and a 14-day free trial with no card. At $29 it is the cheapest way on this page to start tracking brand mentions in ChatGPT, Google AI Overviews, Perplexity and Copilot. It has nothing to say about a competitor's traffic or audience, so it is an alternative to Similarweb's AEO module, not to Similarweb.
Other Similarweb alternatives worth knowing
Peec AI is another AI-visibility specialist, from $95/mo billed monthly or $80/mo billed annually, with unlimited seats on every plan, which is a pointed contrast with Similarweb's one-seat rule. seoClarity publishes floors from $2,500 a month and Botify is quote-only; both sit at the enterprise end and are only worth a call if you are already in that budget bracket. For the free public tools, Similarweb's own Website Traffic Checker remains the quickest way to sanity-check a competitor before paying anyone.
Which Similarweb alternative should you pick?
If you want the broadest suite, Semrush. If backlink data or a free tier for your own site matters most, Ahrefs. If you need API, MCP and more than one seat without a sales call, SE Ranking. If price is the constraint, Serpstat at $69 or Moz at $49. If AI search visibility is the whole job, Profound for depth or Otterly.ai for the cheapest start.
When Similarweb is still the right choice
Similarweb is still the right pick when the question is about a site you cannot see inside: market sizing, share of traffic, a competitor's channel mix, audience overlap, or where a rival's referrals come from. None of the tools above model third-party traffic to the same standard, and for a strategy team, an agency pitching new business or an investor, that layer is the product. It is also a fair single purchase for a marketer who wants traffic intelligence, SEO and AEO in one bill and only needs one login.
