Extensions are small software programs that customize the browsing experience. They let users tailor Chrome functionality and behaviour in many ways, providing things like:
- Productivity tools
- Web page content enrichment
- Information aggregation
- Fun and games
Extensions let you “extend” the browser by using APIs to modify browser behaviour and access web content. Extensions operate by means of an end-user UI and a developer API
An extension must fulfil a single purpose that is narrowly defined and easy to understand. A single extension can include multiple components and a range of functionality, as long as everything contributes towards a common purpose. User interfaces should be minimal and have intent.
Most Chrome users get extensions from the Chrome Web Store. Developers across the globe publish their extensions in the Chrome Web Store where they are reviewed and made available to end users.
Some organizations use enterprise policies to install extensions on their user’s devices. These extensions may either be fetched from the Chrome Web Store or hosted on the organization’s web servers.
You can distribute your extensions through the Chrome Developer Dashboard, publishing them to the Chrome Web Store.
