What is Cookie Consent?

Cookie Consent is a lightweight JavaScript plugin for alerting users about the use of cookies on your website.

It is designed to help you quickly comply with the EU Cookie Law, CCPA, GDPR and other privacy laws. We made it fast, free, and relatively painless.

Cookie Consent is seen over 2 BILLION times every month and is used on millions of sites, making this by far the most popular consent project on the internet.

We welcome community contributions and actively review pull requests.

Hosted Zero Config Consent

Our parent company Osano actively maintains this open source project. Osano is a B-corp and is backed by millions of dollars in venture capital to create data privacy tools for the world. Our mission is to create transparency in data, please consider joining our team.

Ensuring that your website is compliant with various laws can be complicated. To effectively use any open source consent manager, you will need to do GeoIP lookups, adjust the consent types based on visitor location, callback and save consents in a database, and create callbacks to load scripts after consent is granted.

Osano offers a completely free hosted consent management platform, with additional features. If you have a high traffic website or need additional privacy tools, Osano offers paid plans as well. Unless you specifically need the open source tool, most website owners will be better served by the hosted version. If you use Osano for your business, please support continued development by purchasing a paid plan.

The hosted version of the cookie consent manager provides additional capabilities such as:

  • Multi-lingual, translated into 38 languages and growing. Visitors automatically see the dialog in their browser or OS preferred language.
  • Consents are stored automatically on the blockchain. REST API calls are available to developers to search and browse the consent records.
  • 3rd party script blocking and loading does not require callbacks but is instead configurable from a dashboard providing developers with control over what the marketing team can enable or disable.
  • Hosted on AWS Cloudfront with edges around the globe for

Basic Use

With version 4.0 you only need to attach the script as we've bundled everything together now. The initialization style has changed as have the callbacks (they're gone). Please see the text below to get started. Then, take a look at updated API via the docs.


import CC from "CookieConsent"
// or
const CC = require( "CookieConsent" )


const CC = window.CookieConsent
const cc = new CC({
  type   : "categories"
Lifecycle hooks, are now events:
cc.on( "initialized", ( ...args ) => console.log( args ) )
cc.on( "error", console.error )
cc.on( "popupOpened", () => console.log( "Popup Open" ) )
cc.on( "popupClosed", () => console.log( "Popup Closed" ) )
cc.on( "revokeChoice", () => console.log( "Popup Reset" ) )
cc.on( "statusChanged", ( ...args ) => console.log( args ) )
