Cookilio vs Didomi: Sovereign CMP or Enterprise Platform?

Cookilio vs Didomi: Do You Really Need an Enterprise CMP?

There’s a tendency in the software world: believing that more expensive means more serious. That more complex means more complete. That if a solution targets large corporations, it must be better.

Didomi is an enterprise CMP. Headquartered in Paris, global presence, Fortune 500 clients, IAB TCF certification, multi-regulation support (GDPR, CCPA, LGPD). A solution built for organizations operating across dozens of markets with millions of daily pageviews.

Cookilio, published by DPLIANCE, is a sovereign CMP at EUR 9 excl. tax/month. Self-hosted, with server-side consent proof, an ultra-lightweight widget, and a simple philosophy: consent is a right to respect, not data to monetize.

The question isn’t “which is the best CMP?” but “which CMP fits your actual needs?”

Two Worlds, Two Scales, Two Philosophies

Didomi: The CMP for Multinationals

Didomi has positioned itself as the enterprise reference for consent management. Its offering is built for complex organizations (source: didomi.io):

Multi-regulation: GDPR, CCPA/CPRA, VCDPA, CTDPA, CPA, Law 25 (Quebec), LGPD (Brazil), PDPD (Vietnam), PIPA (South Korea). Didomi covers legislation in dozens of countries.
IAB TCF v2.3: Full certification for the Transparency and Consent Framework, essential for large-scale programmatic advertising (source: didomi.io/regulations/tcf-2-3).
Advanced consent analytics: Detailed dashboards, consent rate metrics, tracking over time.
A/B testing: Consent banner optimization.
Multi-language: 45+ languages natively supported.
Geo-targeting: The right banner, in the right format, based on user location.
Cross-device: Consent recognition across a single user’s devices.
Google Consent Mode v2: Certified integration.

It’s impressive. It’s also designed for companies operating at international scale with dedicated legal, technical, and marketing teams.

Cookilio: The CMP for Sovereign SMBs

Cookilio starts from a different observation. The majority of European businesses are not multinationals. They don’t operate in 45 languages. They don’t need TCF for programmatic advertising. They need:

A compliant, clear consent banner
Solid consent proof in case of a CNIL (French data protection authority) audit
Control over their data
A comprehensible, predictable price

Cookilio meets these needs without the extras. The multi-step wizard banner guides the user. Server-side proof with correlation IDs is stored in your database. The Preact widget is ultra-lightweight. The price is fixed: EUR 9 excl. tax/month.

Pricing: The Most Visible Difference

Didomi: Custom Quotes, Typically EUR 500+/month

Didomi doesn’t publish a fixed pricing grid. The company offers three plans — Consent Essentials, Core Privacy UX, Privacy UX Plus — with custom quotes (source: didomi.io/offers). Based on market feedback and available comparisons, pricing typically ranges between EUR 500 and EUR 1,000/month for enterprise plans, with variations based on volume and features (source: SaaSWorthy).

On top of that, there are typically:

Onboarding fees
Annual commitments
Additional costs for advanced features (DSAR, SSO, etc.)

Cookilio: EUR 9 excl. tax/month + EUR 250 excl. tax Setup

Cookilio’s pricing fits in one line:

Subscription: EUR 9 excl. tax/month, no traffic tiers
Setup: EUR 250 excl. tax, one-time fee, setup support included

First year: EUR 358 excl. tax. Following years: EUR 108 excl. tax.

In other words, Cookilio’s annual budget often represents less than one month of Didomi.

Sovereignty: A Political and Technical Choice

Didomi is a French company. That’s a positive point in the CMP landscape dominated by American players (OneTrust, CookieBot/Usercentrics). But Didomi remains a SaaS: your users’ consent data is stored on Didomi’s infrastructure.

With Cookilio, data stays on your infrastructure. Your MariaDB database, your servers, your hosting provider. No dependency on a third party for something as critical as consent proof.

For organizations subject to sovereignty constraints — local governments, administrations, companies in regulated sectors (healthcare, finance, defense) — this difference is fundamental. France’s “Cloud au centre” government doctrine pushes administrations toward sovereign solutions. Cookilio fits this approach.

Enterprise Features: Do You Actually Need Them?

Let’s be honest: Didomi offers features that Cookilio doesn’t. The real question is whether you need them.

TCF is a standard developed by the IAB (Interactive Advertising Bureau) for programmatic advertising. It allows ad exchanges, SSPs, and DSPs to verify user consent in a standardized way.

You need it if: you monetize your audience through programmatic advertising (display, video, native ads) at scale.

You don’t need it if: you run a business website, an e-commerce site, an institutional site, a SaaS, or any site that doesn’t rely on programmatic advertising as its business model.

The vast majority of European SMBs don’t need TCF.

Multi-regulation (CCPA, LGPD, etc.)

Didomi handles legislation from dozens of countries. This is essential for a multinational operating in Brazil, California, and South Korea simultaneously.

You need it if: your site targets users in multiple jurisdictions outside the EU.

You don’t need it if: your market is within the European Union. The GDPR covers the entire EEA.

Native Multi-language (45+ Languages)

You need it if: your site exists in dozens of languages.

You don’t need it if: your site is in one language or a handful. Cookilio’s texts are fully customizable.

These are useful features for large organizations looking to optimize consent rates at scale. For an SMB, Cookilio’s basic admin interface metrics are sufficient.

Integration: Simplicity vs Ecosystem

Didomi: A Complete Ecosystem

Didomi integrates with practically everything: Google Tag Manager, Adobe Analytics, Salesforce, HubSpot, mobile SDKs (iOS, Android), connected TVs (OTT/CTV). Onboarding is handled by a dedicated team. It’s powerful, but integration complexity is proportional to the ecosystem’s richness.

Installing Cookilio comes down to:

Adding the Preact widget to your site (one script)
Configuring your vendors in the Angular admin interface
Defining approval and rejection scripts for each vendor

Setup fees (EUR 250 excl. tax) include DPLIANCE support. No weeks of onboarding, no training sessions, no workshops.

The Hidden Cost of Over-Engineering

Choosing an enterprise solution when you’re an SMB means paying for complexity you don’t use. It also means:

Wasted time configuring unnecessary features
Dependency on a provider for simple modifications
Budget disproportionate to the actual need
Technical debt from an overly heavy integration

CNIL doesn’t sanction companies for not having A/B testing on their banner. It sanctions those who don’t collect compliant consent and those who can’t provide proof. In 2025, 21 organizations were sanctioned for tracker-related violations, totaling nearly 487 million euros (source: CNIL 2025 report).

Cookilio focuses on what matters: compliant consent, server-side proof, total sovereignty.

FAQ

Is Didomi French?

Yes. Didomi was founded in 2017 in Paris. It’s a French company with an international presence. However, as a SaaS, consent data is hosted on Didomi’s infrastructure, not on your servers. Cookilio, also French via DPLIANCE, is self-hosted.

Can you migrate from Didomi to Cookilio?

Yes. Migration involves reconfiguring your vendors in Cookilio’s admin interface and integrating the Preact widget on your site to replace the Didomi SDK. New consents will be recorded in your database. Historical records remain with Didomi until your contract expires. Contact DPLIANCE for support.

Can Cookilio handle a high-traffic site?

Yes. Cookilio’s architecture (NestJS + MariaDB) is designed to scale. The Preact widget is ultra-lightweight and doesn’t impact performance, even on high-traffic sites. The advantage of self-hosting is that you size your infrastructure according to your needs.

Cookilio’s per-vendor script blocking allows you to manage Google consent in a granular way. Configuration is done manually via approval and rejection scripts, without a native certified Google Consent Mode v2 integration like Didomi offers.

How to justify choosing Cookilio over Didomi to a DPO?

Three arguments: (1) consent proof is stored on your own servers, not with a third party — that’s an additional guarantee during an audit; (2) the cost is 10 to 50 times lower for an SMB, without compromising compliance; (3) self-hosting meets digital sovereignty requirements, a criterion increasingly valued by CNIL and European authorities.

A CMP’s complexity doesn’t determine its compliance. What matters is proof, sovereignty, and respecting the user’s choice. Cookilio does exactly that — without extras, without surcharges, without dependency.
