Cookie Consent by SynapxLab review
A flexible self-hosted consent layer with paid server-side audit logging.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cookie Consent by SynapxLab is an open-source cookie consent management platform for websites, APIs, and self-hosted deployments. It displays customizable banners, stores visitor choices locally, blocks configured third-party scripts until consent, and supports Google Consent Mode v2. It suits teams that want control over implementation and a consent layer that can be adapted to common web frameworks, particularly when open-source distribution and consent logging are priorities.
The base package is free and MIT-licensed. Optional Consent Logger plans add server-side consent logging and audit records: Consent Logger 0–2,000 costs €15 per month, 2K–20K costs €35 per month, and 20K–200K costs €75 per month. The 200K+ plan includes consent logging, while its price is not specified here. Billing is monthly and volume-based, and it can be aggregated across sites or calculated individually. This structure keeps the core banner available without charge while placing server-side records in a paid tier.
Its integration surface covers Google Analytics 4, Google Tag Manager, Matomo, Mixpanel, Amplitude, Plausible Analytics, Hotjar, Microsoft Clarity, advertising pixels, chat tools, CRM services, and other listed platforms. A JavaScript API supports opening, resetting, and reading consent preferences, while 16 preconfigured third-party services support common configurations. The trade-off is a narrower localization and standards profile: the interface has 13 languages and the product does not include verified IAB support. Choose it for customizable, self-hosted consent control with optional audit logging; consider another platform if verified IAB support or broader language coverage is essential.
