Our verdict: Didomi and FlowConsent are both French CMPs, but they serve different customers. Didomi is a full platform for enterprises and publishers: IAB TCF 2.3, Google certification, A/B testing, cross-domain and cross-device sync, apps and connected TV, all on quote. FlowConsent is a simple CMP with public pricing, free up to 25,000 sessions per month and installed in 10 minutes. For an SME website, an agency or an online store, FlowConsent covers the essentials on a budget you know upfront. For a publisher living on programmatic advertising or a multichannel group, Didomi is the stronger choice.
What is a CMP and why do you need one?
A Consent Management Platform (CMP) lets a website comply with the GDPR and the ePrivacy Directive for cookies and trackers. It is used to:
- Display a consent banner that meets regulator guidance
- Collect and record visitor choices
- Block non-essential cookies before consent
- Keep proof of consent (consent log)
- Pass consent signals to advertising and analytics tools, in particular through Google Consent Mode v2
European data protection authorities regularly fine cookie violations, and GDPR fines can reach €20 million or 4% of global turnover. A well-configured CMP also protects your analytics: Google requires consent signals for some advertising features in Europe.
FlowConsent overview
What is FlowConsent?
FlowConsent is a French consent management solution launched in 2024. It focuses on the cookie banner and consent on websites, with one goal: make GDPR compliance accessible to everyone, at a publicly listed price.

Didomi overview
What is Didomi?
Didomi is a French company founded in 2017 in Paris, which has become one of Europe's leading consent management vendors. It sped up in 2025: in April, it raised funding from the investment firm Marlin Equity Partners and acquired Addingwell, a server-side tagging specialist based in Lille; in July, it acquired Sourcepoint, a US CMP widely used by news publishers.
Didomi's philosophy
Didomi targets organizations for which consent is a revenue issue: publishers, media, brands and international groups. Its promise goes beyond compliance: maximize consent rates through A/B testing and analytics, unify consent across sites, apps and devices, and prepare for server-side data collection.

Didomi pricing (October 2026)
Didomi offers three consent management plans, all on quote:
Essential (on quote)
- Multi-regulation compliance
- Banner customized to your branding
- Consent analytics and proof of consent
- A/B testing
- Cross-domain and cross-device sync
- Unlimited domains
Advanced (on quote), presented as the most popular
- Everything in Essential
- Focused on compliance auditing and monitoring
- Higher support and SLA level
Premium (on quote)
- Everything in Advanced
- White labeling
- Advanced analytics exports and data warehouse export
- Admin API
- SAML SSO
The price depends on monthly unique visitors (MUV). Other products have their own metric: number of scans for compliance monitoring, database size and API calls for preference management, number of requests for server-side tagging.
Sessions or unique visitors: what changes
The two vendors do not measure the same thing.
- FlowConsent counts sessions. A visitor who comes back four times in a month counts as four sessions.
- Didomi counts monthly unique visitors. The same visitor counts once.
For a site with many returning visitors, Didomi's metric is therefore mechanically lower. That alone is not enough to compare prices, since Didomi does not publish the price attached to a given volume.
What this means in practice
Small site (10,000 sessions per month)
- FlowConsent: free
- Didomi: on quote
Mid-sized site (50,000 sessions per month)
- FlowConsent: €14.99/month excl. VAT, or €179.88 per year
- Didomi: on quote
Large site (100,000 sessions per month)
- FlowConsent: €14.99/month, or €179.88 per year
- Didomi: on quote
Very large site (500,000 sessions per month)
- FlowConsent: Enterprise plan on quote
- Didomi: on quote
Since Didomi has no public prices, we do not put a figure on savings. The best method is simple: ask Didomi for a quote for your volume and compare it with the €179.88 per year of FlowConsent's Pro plan, or €0 if you stay under 25,000 sessions per month.
