So, over the course of the past few weeks, I have become familiar with the Squarespace 7 platform. Going in, my initial thought was "how different could Squarespace be from Weebly"... Very different.
In this article, I will describe some of the principle differences between Squarespace and Weebly's powerful web development platforms.
Interface: When you log into Weebly, you are greeted by a summary dashboard that shows statistics about page views, lists different sites you own, and provides dedicated access to administrative functions such as account and payment information. From the dashboard, you can enter the editor. Once in the editor, Weebly has a side panel on the left side containing all of the HTML elements (called Blocks in Squarespace) that one can employ in their site. A generous amount of screen space is dedicated to your website which you can interact with and edit. Weebly also has navigation along the top of the editor with options that allow you to access more "global" elements of the site such as domain attachment, SSL certificates, favicons, site membership, etc which comes out in a pop-out window on top of your site.
When you log into Squarespace, you are in the editor. They have a larger left side panel from which you control all aspects of your site, where by contrast, Weebly breaks it up into different access points.
Mobile Site Rendering: Both Weebly and Squarespace automatically create a mobile version of your site for viewing on smartphones which you do not have much control over. Squarespace's mobile sites look significantly better.
Platforms on Which the Editor Works: Weebly has an iOS and an Android app that allows you to edit your site from an iPad, iPhone, Android Tablet, or Android Smartphone. Both platforms obviously work on laptop and desktop computers. With that said, Weebly works really smoothly on the Asus C300 chromebook we provide to students as part of the Interfaced Scholar program (I am using one to write this right now), whereas Squarespace really needs a full blown computer with generous CPU, RAM, and graphics capacity to run smoothly.
Cost: The cheapest Weebly package is cheaper than Squarespace's cheapest package whereas Squarespace's most expensive option is more expensive than Weebly's (if you pay for multiple years in advance with Weebly).
Themes/Templates: Weebly has WAY more themes and templates than Squarespace. With that said, there is the old adage of "quality vs quantity". Each of Squarespace's comparatively fewer themes are very premium while Weebly has a lot of templates I would never touch. Squarespace also offers more modern options like Index pages (sites where the whole site is one page you just scroll through, very popular right now) and also the ability to add a video to a slideshow or as a background image to a header (also a modern feature).
Overall Thoughts: On the whole, Weebly has the superior editing platform, however, with painstaking effort and throwing yourself into Squarespace's platform, you have the potential to make a more impressive looking site, PROVIDED that you have really high quality pictures and videos to employ, and further if you have a VERY SPECIFIC set of fonts and colors you want to use on the site.
