The best consent management platforms in 2026, compared
The best consent management platform depends on how your site earns. Publishers showing Google ads in Europe need a Google certified CMP with the IAB TCF, such as Cookiebot, Usercentrics or CookieYes. Advertisers need Consent Mode v2 set before any tag fires, then a plan billed on the meter that suits their traffic.
We compared ten platforms on price, what each one bills on, Google certification and TCF support, using each vendor’s own pricing page on 2 October 2026.
Which consent management platform is best in 2026?
- Cookiebot: small and medium sites that want a well known name.
- Usercentrics: web, app and connected TV consent on one contract.
- CookieYes: quick self serve setup on a small site.
- OneTrust: large companies buying a full privacy programme.
- Didomi: publishers that test and tune consent flows.
- iubenda: a banner bundled with policy generators.
- Complianz: WordPress sites.
- Termly: small businesses that also want policy templates.
- Osano: mid market teams running a wider privacy programme.
- Velo: marketing teams and agencies running several sites on Consent Mode v2 at one price.

Do you need a Google certified CMP?
Only if you show Google ads on your own site. Since 16 January 2024, publishers using AdSense, Ad Manager or AdMob need a Google certified CMP that integrates with the IAB’s Transparency and Consent Framework to serve personalised ads in the EEA and the UK. Switzerland followed on 31 July 2024. The rule is on Google’s CMP requirements page.
Advertisers need something else. Google Ads and GA4 need a correct Consent Mode v2 signal, which means the banner sets consent defaults before any Google tag fires. Test your own install with our guide to checking your banner’s Consent Mode v2 signal.
What does each CMP actually charge you for?
Two plans at the same price can bill very differently.
Same traffic, six different meters.
A content site with thousands of articles and modest traffic pays more on a subpage meter than on a session meter, and a small shop with heavy traffic is the opposite. If you run several sites, check the domain rules too: some plans price each domain on its own.
The ten platforms, one by one
1. Cookiebot
Part of Usercentrics, Cookiebot prices each domain by subpages, not traffic, which suits busy sites with few URLs. TCF support comes with Premium. Worth checking: if a scan finds more subpages than your plan allows, you move up a tier at the end of the billing cycle. Full plan list in our Cookiebot comparison.
2. Usercentrics
Usercentrics bills its web CMP on monthly sessions and is certified for web, app and connected TV. Each plan limits domains, and a subdomain counts as a domain of its own. Worth checking: TCF v2.3 starts on Pro, and going over a session limit adjusts the plan automatically. See our Usercentrics comparison.
3. CookieYes
CookieYes prices each domain by pageviews, counting every load or reload of a page with its code, and lists US dollars before tax. Worth checking: an account holds only one free plan, so every further domain needs its own paid plan. See our CookieYes comparison.
4. OneTrust
OneTrust sells consent inside a wider privacy suite. Its CMP Base and CMP Suite packages cover web, app and connected TV, priced on average daily visitors across all properties. Worth checking: both are quote only after a sales call. Our OneTrust comparison lists what each package covers.
5. Didomi
Didomi serves publishers and larger brands, with consent flow testing and unlimited domains. Worth checking: there is no self serve price.
6. iubenda
iubenda bundles the banner with privacy policy and terms generators and bills on pageviews, with a small charge per extra thousand. Worth checking: on the free plan, the banner stops showing once the monthly pageview cap is reached, so size the plan to your traffic.
7. Complianz
Complianz is a WordPress plugin priced by site, with unlimited pageviews and consent records. Worth checking: it is built for WordPress, so sites on other platforms need a different tool.
8. Termly
Termly pairs a banner with policy generators for small businesses and bills on banner views. Worth checking: TCF v2.3 is on the Pro+ and Agency plans only.
9. Osano
Osano sells consent as part of a wider privacy platform for mid market companies. Worth checking: the first paid plan, Plus, starts at $199 a month.
10. Velo
Velo is our product, so weigh this entry with that in mind. It is a consent banner with Google Consent Mode v2 built in, in early access, for marketing teams and agencies. Pro covers unlimited sites on one session allowance, and advanced Consent Mode, the Tag Manager template and the full consent log are on every plan. Worth checking: Velo is not yet a TCF CMP, so it does not suit AdSense or Ad Manager in Europe. See our TCF status page.
How do you choose a CMP for your site?
Decide whether you need the TCF
If you sell ad space through AdSense, Ad Manager or AdMob to visitors in the EEA, the UK or Switzerland, shortlist only Google certified CMPs. If you only buy ads, you do not need the TCF.
Check the Consent Mode setup
Confirm the platform sets the consent defaults before any Google tag loads, and whether it runs basic or advanced mode. Our post on basic and advanced Consent Mode explains the difference.
Price it on your own numbers
Find the meter each plan uses and read your figure for it. Treat analytics sessions as a floor, since a blocking banner keeps visitors who decline out of them.
Count your domains the way the plan does
Check whether subdomains, staging sites and country sites are billed separately. This is where agency costs usually grow.
Test it on a decline
Install it, refuse consent and watch which tags still fire. An accept proves very little; a decline shows whether the setup works.

Common questions
What people ask about this topic.
What is the best consent management platform in 2026?
It depends on how your site earns. Publishers showing AdSense, Ad Manager or AdMob ads in the EEA, the UK or Switzerland need a Google certified CMP with the IAB TCF, such as Cookiebot, Usercentrics, CookieYes, Didomi or iubenda. Advertisers mostly need a correct Consent Mode v2 signal, then a plan priced on the meter that suits their site.
Is there a free consent management platform?
Yes. Cookiebot, Usercentrics, CookieYes, iubenda, Complianz, Termly, Osano and Velo all had free plans on 2 October 2026. Each caps subpages, sessions, pageviews, visitors or banner views, usually on one domain, so check what happens at the cap.
Do I need a Google certified CMP?
Yes if you serve personalised ads through AdSense, Ad Manager or AdMob to visitors in the EEA or the UK (since 16 January 2024) or Switzerland (since 31 July 2024). If you only buy ads, Google does not require one, but Google Ads and GA4 still need a correct Consent Mode v2 signal.
Which CMP is cheapest for several websites?
Check how the plan counts sites first. Cookiebot and CookieYes price each domain separately, Usercentrics limits domains per plan, and Complianz prices by site. Velo Pro covers unlimited sites on one session allowance from 7 euros a month, VAT included.
Does Velo support the IAB TCF?
Not yet. Velo is not a registered TCF CMP or on Google's certified list, so it does not suit sites that need one for AdSense, Ad Manager or AdMob. It sets Google Consent Mode v2 on every plan, which is what advertisers need for Google Ads and GA4.
