Companies Using Cookie Consent by Osano

As of our March 2026 crawl, TechnologyChecker.io tracks 110,047 domains running Cookie Consent by Osano and 56,857 enriched company profiles matched to LinkedIn data. This free open-source JavaScript plugin is one of the most widely deployed consent banners on the web, but our data reveals a churn story that tells as much as the adoption numbers.

Growth Trajectory

Cookie Consent by Osano's adoption history tracks directly to regulatory enforcement milestones. The 2019 explosion, from 1,463 to 20,569 domains in four months, coincided with GDPR's first enforcement wave and the Planet49 ruling mandating opt-in consent. Growth continued through 2022-2024, peaking around 100,000+ active domains. But the 2024-2025 period shows a plateau and decline: 100,267 to 84,188 active domains. We've detected 262,587 sites that previously used the plugin. A 70% churn rate that's the highest in the consent management space. That signals a combination of free-tier limitations driving upgrades to paid competitors and natural churn as companies outgrow a one-line-of-code solution.

Sales Signal: The 262,587 churned domains represent companies that needed a consent banner and chose Osano, then left. They're pre-qualified privacy-aware leads for any CMP vendor that can articulate what Osano's free tier lacks: automatic cookie discovery, consent analytics, and server-side blocking.

"262,587 sites removed Cookie Consent by Osano after deploying it, that 70% churn rate creates the largest consent-tool replacement opportunity in our dataset." - Mehmet Suleyman, CEO at TechnologyChecker.io

Customer Profile

Our enriched dataset of 56,857 companies reveals a split personality. Enterprise logos like Deloitte, Oracle, and Shell coexist with a core demographic of small businesses. The 36.85% concentration in 2010s-founded companies makes sense, these businesses launched post-smartphone, built mobile-first, and hit scale during GDPR's 2018 rollout. They didn't inherit legacy consent implementations. In contrast, pre-1960 companies (8.05%) like Shell (1833) and Bayer (1863) deploy the plugin on digital transformation projects, modernizing old web properties without disrupting core systems. Large enterprises use Cookie Consent by Osano on secondary domains (career sites, brand portals, internal tools) where a free solution works fine, while reserving Cookiebot or OneTrust for revenue-critical ecommerce properties.

Sales Signal: Multi-domain enterprises showing Cookie Consent by Osano on 2-5 subdomains have distributed IT budgets ripe for centralized CMP solutions. The free tier on secondary sites is a foot in the door, if you can demonstrate unified consent management across all properties, the upgrade pitch becomes compelling.

Industry and Geographic Concentration

Geographic signals point to GDPR and CCPA as the primary adoption drivers. The US, UK, France, and Switzerland dominate our enrichment sample, aligning with the strictest enforcement regimes. The plugin's claimed support for 50+ country jurisdictions suggests emerging market penetration (Brazil's LGPD, India's DPDP Act) that our Western-biased crawl probably underrepresents. Industry distribution is broad: professional services, technology, retail, and consulting lead, but no single vertical exceeds 8%, confirming Cookie Consent by Osano is a horizontal compliance tool deployed wherever a website needs a consent banner, regardless of what the business does.

Sales Signal: For teams selling privacy tech in Europe, Cookie Consent by Osano detection is a qualifying signal. These companies have acknowledged their consent obligations. The question isn't whether they need compliance tooling but whether the free tier meets their actual requirements. Target companies in regulated industries (finance, healthcare, insurance) where audit trails and consent logs matter more than banner aesthetics.

Migration Patterns

The 70% churn rate (262,587 previously-used vs. 110,047 active) is the dominant migration signal. Most departures don't go to a single competitor, they fragment across Cookiebot, OneTrust, CookieYes, Termly, and Usercentrics, depending on company size and budget. The free-to-paid upgrade path is where companies hit friction: Osano's paid plans offer cookie blocking and DSAR automation, but at price points where mid-market CMPs (Termly, CookieYes) offer similar features for less. Enterprise companies requiring SOC 2 compliance documentation and consent analytics tend to skip Osano's paid tier entirely and move to OneTrust or TrustArc.

Sales Signal: Companies that recently removed Cookie Consent by Osano are actively evaluating alternatives, monitor TechnologyChecker.io for technology changes on your target accounts. A site dropping Osano is a high-intent signal that someone just opened a CMP budget.

"The competitive set breaks into three tiers, and Osano straddles two of them, free users resist upgrades while paid customers compare unfavorably to OneTrust on depth." - Mehmet Suleyman, CEO at TechnologyChecker.io

Technology Ecosystem

The 67.8% overlap with Google Tag Manager (38,551 companies) is tactically significant. Cookie Consent by Osano integrates via GTM triggers, meaning users already have mature tag governance. They can swap CMPs without developer friction. That lowers switching costs, threatening Osano's retention but creating opportunity for competitors. jQuery appears on 92.31% of sites, indicating aging tech stacks. Modern frameworks like React, Vue, and Next.js appear far less frequently. Cookie Consent by Osano users tend to run conservative infrastructure, privacy teams at these organizations likely face IT bureaucracy, slow release cycles, and risk-averse leadership, all factors favoring simple plug-and-play solutions.

Sales Signal: The 67.8% GTM overlap means 38,551 companies can swap their consent banner without touching application code. If your CMP offers a GTM template. That's your lead-in: "You can migrate in 15 minutes without developer involvement."

G2 Review Signals

G2 reviewers cite intuitive ease of use (21 mentions) as the top strength and high cost (6 mentions) as the primary complaint. A paradox for a tool with a free tier, suggesting the criticism targets Osano's paid plans rather than the open-source plugin. Exceptional customer support (17 mentions) earns strong praise, while lack of customization (6 mentions) surfaces as a secondary concern. Our migration data confirms the customization gap: enterprises on secondary domains tolerate basic banners, but revenue-critical properties need branded consent experiences with A/B-tested acceptance rates, features Osano's free tier doesn't offer. The 3.5:1 positive-to-negative ratio shows strong satisfaction among those who stay, but the 70% churn rate tells you most don't.

Sales Signal: The 17-mention support praise is Osano's strongest retention lever. If you compete, don't attack support quality, focus on customization depth, automatic cookie scanning, and consent rate optimization as your differentiators.

Key Takeaways

1. 70% churn rate, highest in consent management. 262,587 former deployments vs. 110,047 active creates the largest CMP replacement opportunity we track.

2. Split personality customer base. Fortune 500 enterprises deploy it on secondary domains while micro-businesses use it as their only consent solution.

3. GTM integration lowers switching costs. 67.8% of sites use Google Tag Manager, meaning CMP swaps require no developer work. A threat to retention and an opening for competitors.

4. GDPR and CCPA drive adoption geography. US, UK, France, and Switzerland dominate, aligning with the strictest privacy enforcement regimes.

5. Aging tech stacks dominate. 92.31% jQuery presence signals conservative infrastructure and risk-averse organizations, position upgrades as low-friction, not transformational.
