Local Development

Git Built-in

All Squarespace template repositories are exposed via Git automatically, so you can work with a team and easily roll back.

JSON Data Store

Query any page as JSON to access your site's data in a structured way. Your website content is an API.


Our familiar template language has very few language constructs to learn, yet offers the power and expressiveness needed to implement any design.


Whether you have 10 or 10,000 visitors a day, your site will remain online. We host Squarespace.com on the same servers, so we're in this together.

Content Delivery Network

Our built-in CDN reduces load times using geographically distributed servers. Your assets will be delivered quickly to any place on Earth.
