Pick
OnCrawl
OnCrawl is the right pick if your team prefers their approach and pricing fits.
Head-to-head review · Updated June 2026
OnCrawl vs Similarweb: which one wins in 2026?
OnCrawl and Similarweb both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Similarweb
Pick Similarweb if SOC 2 Type 2 matters for your security review.
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for OnCrawl
Founded by Francois Goube, Tanguy Moal, based in Bordeaux, France. On their site they list 10 named customers including Adidas, L'Oreal, Ticketmaster, Harrods.
Enterprise SEO data platform combining crawl, logs, and AI insights.
What people praise
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
- Log file analyzer processes 500M+ log lines per day, surfacing how Googlebot, Bingbot, and AI crawlers actually behave on the site.
- Cross-references crawl data, server logs, GSC, GA4, Adobe Analytics, and Majestic backlinks in one analysis - few competitors integrate all five sources.
- 100% unsampled data analysis appeals to enterprise SEOs frustrated with GA4 sampling and Search Console limits.
Where it falls short
- No public pricing - book-a-demo gating means SMBs and indie consultants are filtered out before evaluation.
- Capterra rating of 3.8 is the lowest among major technical SEO crawlers, with reviewers citing UI complexity and pricing opacity.
- Steep learning curve - the platform assumes data-science fluency, which leaves marketers needing a technical SEO specialist to extract value.
- Self-serve onboarding is limited; complex multi-source setups (logs plus crawl plus analytics) typically need OnCrawl's customer success team.
The case for Similarweb
Similarweb has raised Public (NYSE: SMWB) (IPO May 2021 at $1.6B valuation, raised $165M). Founded by Or Offer, based in Tel Aviv, Israel. On their site they list 8 named customers including Google, Walmart, Adidas, eBay. Pricing starts at $35/mo.
Digital intelligence platform with web, app, and search data — recently added AI search visibility.
What people praise
- Traffic and audience data covers millions of websites globally, providing the broadest competitive intelligence dataset of any tool in this category.
- Intuitive UI that lets non-analysts quickly access competitor traffic, top pages, and audience overlap without training.
- Native Salesforce and HubSpot integrations export account lists and lead data directly into CRM, used heavily by sales intelligence teams.
- Snowflake API integration lets enterprises pipe raw traffic data into their data warehouse for blending with internal analytics.
Where it falls short
- Traffic estimates can deviate 100-200% from actual Google Analytics or GSC numbers, especially for low-traffic sites.
- Pricing jumps significantly at renewal, with long-term subscribers reporting unilateral price hikes year over year.
- Contract inflexibility is a common complaint, with mid-term seat additions and module changes requiring full re-negotiation.
- Data accuracy degrades for smaller websites under ~50K monthly visits, making it less useful for SMB competitive research.

When each one wins
When OnCrawl wins
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When Similarweb wins
- Budget is the constraint. Similarweb starts at $35/mo vs OnCrawl's $∞/mo, so on a per-seat basis it's the cheaper way in.
- Procurement requires SOC 2 Type 2. Similarweb has it; OnCrawl doesn't yet.
- Traffic and audience data covers millions of websites globally, providing the broadest competitive intelligence dataset of any tool in this category.
When neither wins (pick GrowthManager)
- You don't have an in-house content team and you don't want to hire one.
- You want one $999/mo invoice instead of stacking OnCrawl plus an agency.
- You need the team that measures to also act on the data, in the same week.
- You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.
Reasons to pick one over the other
Reasons to pick OnCrawl over Similarweb
- Built for the LLM era. OnCrawl was founded in 2013, built around AI search from day one; Similarweb dates back to 2007 and is retrofitting.
- What users praise most. JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
- EU data residency. OnCrawl is HQ'd in Bordeaux, France, which simplifies GDPR data-processor agreements for European buyers.
Reasons to pick Similarweb over OnCrawl
- Lower entry price. Similarweb publishes a clear entry tier at $35/mo; OnCrawl gates pricing.
- Public pricing. Similarweb publishes 4 tiers on its website; OnCrawl requires a sales conversation.
- SOC 2 Type 2. Similarweb carries SOC 2 Type 2; OnCrawl does not yet, which can hold up procurement.
- More verified reviews. Similarweb has 1,577 G2 reviews vs OnCrawl's none on file, so the average rating carries more weight.
- More mature platform. Similarweb (founded 2007) has had more time to harden the product than OnCrawl (2013).
- What users praise most. Traffic and audience data covers millions of websites globally, providing the broadest competitive intelligence dataset of any tool in this category.
Switching from one to the other
From OnCrawl to Similarweb
Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most Similarweb setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Similarweb's data againstOnCrawl's; one to two weeks of full reconciliation before you cancel OnCrawl. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Similarweb to OnCrawl
Same flow in reverse. Export from Similarweb, import to OnCrawl. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both OnCrawl and Similarwebare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, OnCrawl or Similarweb?
Honestly: neither one fully solves the problem. OnCrawl and Similarweb are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick OnCrawl for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do OnCrawl and Similarweb cost?
OnCrawl starts at Custom. Similarweb starts at $35/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Do OnCrawl and Similarweb actually improve your AI visibility, or just measure it?
Both OnCrawl and Similarweb are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to OnCrawl and Similarweb?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
