If you’re not familiar with Squarespace, it’s a website builder that allows users to create beautiful websites without any coding knowledge.

One of the best things about Squarespace is that it’s constantly evolving and adding new features. One recent addition is the Extensions store, which offers a range of add-ons that can be used to extend the functionality of your Squarespace site.

Squarespace Extensions are essentially plugins that add additional features and functionality to your Squarespace website. They can be used to add things like social media buttons, contact forms, e-commerce features, and more.

There are a wide variety of extensions available, created by both Squarespace and third-party developers. Some are free to use, while others come with a monthly or one-time fee. Using extensions can help you create a more robust and feature-rich website without having to code anything yourself.

What are Squarespace Extensions?

Squarespace Extensions are tools that help you customize your Squarespace website. They can be used to add features, change website behavior, or integrate with third-party services. In most cases, Extensions are created by Squarespace partners.


When you install an Extension from the Partner Directory, it appears in your site’s Settings panel. If an Extension is no longer available or supported, it’ll be removed from the directory. Extensions are different from Code Blocks because they don’t require code skills to use.

They’re also different from App Showcase items because they don’t need to be approved by Squarespace before you can use them on your site.

Are Squarespace Extensions Free?

There are a few different types of Squarespace extensions, but most of them are free. The only exception to this is the eCommerce extension, which costs $4 per month. However, this extension is not required in order to sell products on your Squarespace site – you can use the built-in eCommerce functionality for free.

Can You Add Extensions to Squarespace?

If you’re looking to add a little something extra to your Squarespace site, you might be wondering if you can add extensions. The short answer is yes! There are a few different ways to add functionality to your Squarespace site using extensions.

One way to do this is by installing a third-party extension. These are programs that are created by developers other than Squarespace, and they can be used to add all sorts of different features to your site.


For example, there are extensions that can help you create forms, manage your social media accounts, or even accept payments on your site.

Installing a third-party extension is easy just head over to the Extension Marketplace and find the one that’s right for you. Once you’ve installed it, all you need to do is follow the instructions on how to use it.

Another way to add functionality to your Squarespace site is by using code injections. This method requires a bit more technical know-how, but it’s still relatively easy to do.

Basically, all you need to do is copy and paste some code into specific parts of your Squarespace template. This code will then allow you to add things like custom CSS or JavaScript snippets onto your site.

If you’re not sure how code injection works, don’t worry -Squarespace has plenty of documentation on their website that can walk you through the process step-by-step.

So there you have it – two different ways that you can add extensions to your Squarespace site! Whether you want an easy-to-use solution or something with a bit more customization potential, there’s an option out there for you.

What Integrations Does Squarespace Have?

Squarespace has integrations with a number of different applications and services. These include social media platforms like Twitter and Facebook, e-commerce platforms like Shopify, and email marketing tools like MailChimp.

The Squarespace platform itself is also highly customizable, so you can use third-party plugins and code snippets to add even more functionality to your site.

In addition, Squarespace offers a number of its own native features that can be used to further extend the capabilities of your website.
