Onesecondbefore CMP review
A focused CMP for teams managing consent across websites and mobile apps.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Onesecondbefore CMP is a consent-management product for websites and mobile applications. It suits teams that need configurable consent bars, IAB TCF 2.2 consent gating, consent-purpose and vendor settings, and stored consent records. Support spans web, iOS, Android, and API use cases, giving mobile teams a focused way to manage consent across more than one application surface. The product is offered by Onesecondbefore, headquartered in Amsterdam, The Netherlands.
The published offer includes Free, Pro, and Enterprise versions, with pricing handled through contact with sales. The Free plan gives the product an accessible starting point, while the tier structure provides a path for organizations that need a broader commercial arrangement. Buyers should assess which plan fits their deployment and operational requirements before selecting a tier. The product’s value is clearest for teams prioritizing consent management rather than a wider marketing technology suite.
Integration and implementation are central strengths. JavaScript supports web deployment, while native Android and iOS SDKs address mobile applications; a REST API provides consent record storage. Google Consent Mode v2 is supported, and the listed integrations include Google Consent Mode and Google Analytics for Firebase. Together, these capabilities make Onesecondbefore CMP a practical fit for mobile teams coordinating consent with analytics. Teams seeking a focused CMP with IAB controls, consent storage, and native mobile options should consider it; organizations looking for AI features or a broader feature set should look elsewhere.
