As of 30 Oct 2026, the panel rates consentmanager 2.5/5 and Didomi 3.5/5 in Consent Management (CMP). Weighted by what each judge cares about, 0 of the 6 judges pick consentmanager and 6 pick Didomi. consentmanager scores higher on 1 of 6 criteria (European sovereignty). Didomi scores higher on 5 of 6 criteria (Scanning & cookie classification, Consent records & proof, Banner & choice architecture, plus 2 more). Provenance — consentmanager: EU-Made; Didomi: EU-Made. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
Didomi is ahead on six of seven criteria — banner and choice 7.5 to 5.2, prior blocking 5.8 to 4.2, scanning and classification 7.8 to 4.2, consent records 7.7 to 4.3, standards and platforms 7.0 to 5.5, each 6 judges to 0, and pricing transparency 2.5 to 0.7 with 5 leans and 1 tie; pricing is not weighted in Didomi's verdicts. Sovereignty is the exception: 6 judges to 0 lean consentmanager, 5.8 versus 4.0. consentmanager's attributes list data residency and subprocessor exposure as EU only, and the verdict documents PlusServer GmbH hosting in Cologne, a data processing agreement and named subprocessors with countries; Didomi's attributes list both as unknown, and its verdict names Amazon Web Services LLC at a Seattle address as host of the vendor's own website. Weighted totals per judge span 6.3 to 7.0 for Didomi and 4.3 to 5.1 for consentmanager. The benches split by criterion, not by judge.
Choose consentmanager if
You need consent data to stay in the EU: consentmanager's data residency attribute reads EU only, while Didomi's reads unknown.
Your vendor review requires subprocessor exposure within the EU only: that attribute reads EU only for consentmanager and unknown for Didomi.
You must sign a data processing agreement with the vendor as processor and review named subprocessors with countries and safeguards before rollout: the verdict documents both for consentmanager.
Your auditors want the hosting entity and corporate chain on record: the verdict names a Swedish entity under Italian parent iubenda and PlusServer GmbH hosting in Cologne.
Choose Didomi if
You need scanning behind logins, from a chosen country, or across up to 20,000 pages: scanning and classification is 7.8 to 4.2, 6 judges to 0 for Didomi.
Your legal team must pull the exact consent UI a user agreed to on any date: Didomi's versions-and-proofs module backs consent records at 7.7 to 4.3.
You want a one-click deny route beside accept and agree/disagree buttons that cannot be disabled: banner and choice is 7.5 to 5.2 for Didomi.
Your stack leans on standards and platform support: standards and platforms is 7.0 to 5.5 in Didomi's favor.
You prioritize prior blocking ahead of consent: it is 5.8 to 4.2 for Didomi, with the verdict noting manual per-vendor Google Tag Manager setup at its low end.

The Publisher Marketing Lead
Runs marketing for an ad-funded news site and an online shop in the same group, where every point of consent rate shows up in ad revenue and in Google Ads conversions. Wants a registered IAB TCF CMP, Google Consent Mode v2 in advanced mode, banner tests within what the law allows, consent shared between the site and the app, and a dashboard that shows where visitors drop off.

Criterion by criterion
Banner & choice architecture
consentmanager
From a revenue standpoint I like what is documented: visitors can grant or refuse consent per purpose and per individual third-party vendor, change their choices afterwards, and are asked again twelve months after their settings; the vendor names AI-supported banner testing and help pages cover reject links and creating your own designs and texts. We found no public information on whether reject carries the same weight as accept on the first layer, per-country banner rules, or banner accessibility, so I stop just above mid-level.
Didomi
The first layer offers one-click accept and deny ("Agree and close", "Disagree and close", a cross button, or "Continue without agreeing"), and the Agree to all and Disagree to all buttons are enabled by default and cannot be disabled — equal-weight choice as a default is exactly what I need before running any banner test. Consent applies per purpose and per vendor, geo-targeting serves a different experience per country and regulation, A/B testing and opt-in rate analytics are documented, and language support with automatic detection is stated (the captured pages give different figures for the count: 45+ on one page, 50+ on another). I found no public information on banner accessibility with a named WCAG level, or on the legal limits of what may be A/B tested.
Prior blocking & script control
consentmanager
The help centre documents automatic blocking of codes and cookies plus a getting-started guide to blocking third-party codes and cookies, which is the core of what I need before consent. We found no public information on placeholders for videos and embeds, tag-manager templates, server-side tagging or a documented way to verify nothing fires early.
Didomi
The documented blocking path is manual: in Google Tag Manager I create one trigger per non-IAB vendor, gated on the "Didomi Vendors Enabled" variable, and the documentation is unusually frank about the traps — combining triggers causes OR logic that drops cookies without consent, trigger groups fire once per page on dynamic sites, and every new tag needs the setup again. Consent state is exposed through events and variables, server-side tagging is available on request, and the compliance monitor treats trackers fired before consent as violations with alerts on new tracker activity, which is real verification. I found no public information on an automatic blocking mode or on content blockers with placeholders for videos, maps and social embeds — the video page only recommends collecting consent before embedded videos launch.
Scanning & cookie classification
consentmanager
A cookie scanner is listed as a core module with its own feature pages, and the help centre addresses how to classify unknown cookies. We found no public information on scan scheduling and depth, coverage of local storage and pixels, or a cookie declaration that updates itself from the scan.
Didomi
The bot scrapes configured domains on a schedule (monthly or weekly depending on plan, with XL scans up to 20,000 pages), can scan behind logins and from a chosen country, and groups trackers as cookies, pixels and local storage with a first-party versus third-party split — depth, region and login coverage are all documented. Every scan produces a time-stamped audit trail, JSON export of full vendor and tracker data, and per-vendor risk assessments, with alerts the moment something changes. I found no public information on a maintained classification database with purposes, providers and lifetimes, or on a cookie declaration that updates itself in several languages.
Consent records & proof
consentmanager
Developer documentation of a consent log protocol with audit trail exists in English and German, and the privacy policy states consent is asked again twelve months after the visitor's settings. We found no public information on what each record contains, how long consent logs are kept, or export of the log.
Didomi
The versions and proofs module captures, versions and retrieves every consent event so legal teams can pull "the exact UI a user agreed to, on any date" — a record tied to the notice version and texts shown, which is what a regulator letter actually asks for. Proofs attach to consent events and are retrievable through an API within 24 hours, cross-device and cross-domain consent unify the record, and an Admin API with batch export exists. I found no public information on a consent ID the visitor can look up, configurable consent expiry, how long consent logs are kept or where, or withdrawal being recorded as its own event.
Frameworks, signals & platforms
consentmanager
This is my home ground: the vendor is named a Google-certified platform, with dedicated pages for Google Consent Mode v2 and IAB TCF for publishers including TCF v2 configuration help, and the module list names mobile app consent and connected TV consent. We found no public information on a registered IAB CMP ID, whether Consent Mode v2 advanced mode is supported, GPP or GPC signals for the US, or an API for managing many domains.
Didomi
Didomi is a Google Certified CMP Partner at gold tier, certified for web, apps and connected TV, and names IAB TCF, GPP, GPC, Microsoft UET and AWS and Amazon consent signals, with a REST API and unlimited domains on a monthly-unique-visitor basis — cross-device consent means a user chooses once across my site and my app, my headline requirement. The captured pages give different figures for the TCF version (v2.2 on one page, 2.4 on another), and I found no public information on a registered IAB Europe CMP ID, on Consent Mode v2 being offered in advanced as well as basic mode (the developer page only says the integration is supported under GDPR), or on agency accounts managing many client sites.
European sovereignty
consentmanager
The chain I can see is European: a Swedish contracting entity under an Italian parent, German and French sales companies, hosting stated with PlusServer in Cologne, a data processing agreement with all customers as a pure processor, and named subprocessors with locations and stated safeguards. We found no public information on where the banner script and consent logs are stored, or on security certifications.
Didomi
The contracting entity is solidly European — Didomi SAS at 137 Boulevard de Sébastopol in Paris, registered with the Paris RCS with a French VAT number — and the company states ISO 27001 certification, encryption in transit and at rest, encrypted point-in-time backups and replication across at least two physically separated data centres. But the legal notice names Amazon Web Services LLC of Seattle as the host, the data-centre regions are not stated, and I found no public information on where the banner script and consent logs are stored, on the subprocessor chain, or on a published data processing agreement.
Pricing transparency
consentmanager
A public pricing page exists and the account area shows self-service orders paid by card or PayPal, but the captured pages state no price per tier, no traffic or domain limits and no scaling rules. I cannot compute the annual cost for my news site and shop from what is public here.
Didomi
Every plan — Essential, Advanced and Premium — says "Contact us"; no price appears anywhere, though the comparison page is generous with what each tier gates (scan frequency, auditing scan counts, SSO seats, analytics export destinations) and states consent management covers unlimited domains on a monthly-unique-visitor basis. A free compliance-monitoring scan exists, but I found no public information on tier prices, page-view or visitor bands with their cost, or what the connected-TV, cross-device and server-side add-ons cost beyond "Upon Request". I cannot compute an annual cost from the public pages alone.
