Consent management

# Yett

Essential

Yett is a small open source JavaScript library that blocks the execution of third-party scripts until the site allows them, typically after the visitor gives consent. It intercepts script tags matching a blacklist or whitelist and releases them on demand. It is a building block for consent tools and does not track visitors itself.
