Companies Using CleanTalk

We detect CleanTalk on 51,302 domains, including First Student, TransPerfect, Delhi University. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Construction (6.62%).

We detect 51,302 domains running CleanTalk across our monthly crawl of live business domains. Company data could be matched for 36,704 of them (71.5%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 2,329 domains carried a CleanTalk detection previously and no longer do.

CleanTalk holds 1% of the Bot Detection & CAPTCHA category, ranking #5. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to CleanTalk include reCAPTCHA (65.26% market share), Cloudflare Bot Management (26.04% market share), Cloudflare Turnstile (3.68% market share), hCaptcha (3.44% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 15,005 matched CleanTalk domains, followed by United Kingdom (3,069), Netherlands (2,172), Germany (2,126), Australia (1,977). These are counts within the 36,704 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 63.69% of the CleanTalk domains we could match to a company record and size — a subset of 36,704 matched companies, not of all 51,302 detected domains. This is followed by 11-50 employees (25.39%) and 51-200 employees (7.54%).

Among the CleanTalk domains we could match to a company with a known founding date, most were founded in the 2010s (34.61%), followed by the 2000s (19.81%). That matched subset is drawn from 36,704 companies and is not representative of all 51,302 detected domains. This suggests CleanTalk is most popular among relatively young companies.

The ideal CleanTalk customer is: Company Size: 1-10 employees, Location: US, UK, or Germany, City: London, New York, Paris, Los Angeles, Founded: 2010-2019, Company Age: ~5-15 years old — based on our analysis of 36,704 enriched companies at TechnologyChecker.io.

CleanTalk is a cloud-based service that blocks spam bots on websites without using CAPTCHAs or puzzles. It screens comments, form submissions, registrations, and orders in real time using behavioral analysis and a global blacklist database. That invisible approach is what the migration data shows people buying it for: 926 domains moved to CleanTalk from reCAPTCHA against 321 going the other way, which is what it looks like when site owners decide a visible challenge costs them more than a subscription does.

The WordPress plugin itself is free to install, but it requires a paid cloud service subscription to work. Pricing starts at $12 per year for one website, making it one of the cheapest anti-spam options available. Multi-site packages run $69/year for 10 sites, $115/year for 20, and $27/month for unlimited sites. New accounts typically get a free trial period to test the service.

Both are cloud-based WordPress anti-spam services, but they differ in scope. CleanTalk protects forms, registrations, and WooCommerce orders in addition to comments, while Akismet primarily targets comment spam. Our data shows CleanTalk on 51,302 active domains, 96.24% of them WordPress, with Contact Form 7 present on a quarter of them, so the form-protection use case is the dominant one in practice rather than a secondary feature.

Yes. CleanTalk is a long-established commercial plugin with a substantial published review history on Trustpilot, GetApp, Capterra and the WordPress.org plugin directory. Our detection data independently confirms 51,302 active domains running it as of August 2026, across companies from one-person consultancies to First Student, Quad and Curtiss-Wright, which is the kind of footprint a service has to earn over years rather than buy.

Yes, cleanTalk integrates with WooCommerce to block spam orders, fake registrations, and bot-generated checkout attempts. Our tech stack data at TechnologyChecker.io shows 20.9% of CleanTalk websites also run WooCommerce, making it the most common e-commerce platform in the CleanTalk network. The plugin filters WooCommerce-specific forms automatically without requiring separate configuration.

CleanTalk offers plugins for WordPress, Joomla, Drupal, and other CMS platforms, plus a universal API for custom websites. In practice the overwhelming majority of deployments are WordPress-based: our detection data puts 96.24% of CleanTalk sites on WordPress, the highest single-platform dependency we measure on any technology. Joomla and Drupal installations exist but are a rounding error against that.

Construction leads at 6.62%, followed by Medical Practices (3.03%), Retail (2.95%), Real Estate (2.89%) and Business Consulting and Services (2.88%), based on 36,704 enriched companies. No industry beyond construction exceeds 3%. The common thread is small firms whose websites exist to collect enquiries through a form, which is the surface spam bots target most reliably.

Yes, that is its primary function. Our tech stack data shows Contact Form 7 on 24.92% of CleanTalk sites, Gravity Forms on 8.58% and WPForms on 2.82%, so roughly a quarter of the install base pairs it with the most widely targeted contact form plugin on the web. CleanTalk screens submissions server-side against its cloud blacklist rather than challenging the visitor, so the form stays a plain form.

CleanTalk reports a 0.05% false-positive rate. When legitimate submissions do get blocked, admins can whitelist specific emails or IP addresses through the CleanTalk dashboard. The Extra Package includes a Personal White List feature. False positives most commonly occur when JavaScript fails to load correctly on the page or when users submit from IP addresses that appear on CleanTalk's global blacklist.

The United States leads with 41.9% of companies whose country we know, followed by the United Kingdom (8.6%), the Netherlands (6.1%), Germany (5.9%), Australia (5.5%) and Canada (4.9%), based on 36,704 enriched companies. The Netherlands placing third is unusual in our data and makes CleanTalk one of the more European tools in this category, with Europe at 36.5% of the base overall.

For a small site, the value case is strong: our data shows 63.69% of CleanTalk companies have 1-10 employees and 89.08% have fifty or fewer, so it is priced and built for exactly this audience. The migration data supports it too, with 926 domains moving to CleanTalk from reCAPTCHA against 321 going the other way, which is what it looks like when small site owners decide they would rather filter spam invisibly than make every visitor click a puzzle.

Yes, beyond anti-spam, CleanTalk's Security add-on includes a web application firewall, malware scanning, brute-force protection, and two-factor authentication, priced separately from the anti-spam subscription. Our data cannot tell you how many CleanTalk sites have the security add-on enabled, since we detect the anti-spam layer rather than the account's plan, so treat the add-on as a product capability rather than something we can size.

The main alternatives are the CAPTCHA widgets CleanTalk displaces: reCAPTCHA (3,315,944 domains), Cloudflare Turnstile (187,176) and hCaptcha (174,847), plus Cloudflare Bot Management (1,323,076) at the edge-filtering end. Within WordPress specifically the closest comparisons are other anti-spam plugins, which sit below our category's detection threshold individually. Note the direction of travel: CleanTalk is net-positive against every one of those competitors, gaining 1,117 domains and losing 504.

TechnologyChecker.io detects 51,302 active domains using CleanTalk as of August 2026. One caveat worth stating plainly: 38,288 of those were first detected between 4 and 13 August, when the set of domains we crawl expanded sharply. Those installations already existed and we had simply not yet crawled the sites carrying them, which we can confirm because 98.5% of the newly-found domains run WordPress, matching the profile of the population we already knew about. Read 51,302 as our current best estimate of CleanTalk's real footprint rather than as recent growth.
