ConsentStack is a consent management platform (CMP) that helps websites get visitor permission to use cookies and tracking tools, in line with privacy laws like GDPR, CCPA, and LGPD. It is built for mid-market teams that need a clear, customizable cookie banner and a simple way to prove they are handling consent correctly, without spending weeks on setup or legal review. Most websites today use analytics, advertising, and marketing tools that collect visitor data. Privacy laws around the world require those sites to ask visitors before that data is collected, store the answer, and respect the choice. ConsentStack handles all three steps. It shows the banner to each visitor, records the response, and tells the rest of the site's tools whether they are allowed to run. The platform is used by marketing, privacy, and operations teams at SaaS companies, e-commerce brands, publishers, and agencies that manage compliance for their own sites or on behalf of clients. It is designed to fit teams that want more control than a basic free banner offers, but do not need the complexity or cost of an enterprise compliance suite. Banners are fully customizable, so teams can match their brand styling, write the copy in their own voice, and translate the experience into the languages their visitors speak. Region-aware behavior lets visitors from different countries or US states see the right banner and default settings for their local privacy rules, which removes the need to maintain separate setups for each jurisdiction. Every visitor choice is captured in an audit-ready consent log with the date, banner version, and policy version attached, giving privacy teams the proof they need during internal reviews or regulator requests. ConsentStack also includes a vendor directory that lists the third-party tools running on a site, what data each one collects, and which consent category it belongs to, which makes it easier to keep privacy policies accurate as a stack changes. Agencies and larger organizations can manage many websites from a single account with controlled access for each user. A typical site can be configured in under five minutes, and updates to banner copy, languages, or vendor settings go live without a developer redeploying.
