Weebly's free online website creator uses a simple widget-based site builder that operates in the web browser. All the site elements are drag-and-drop, and it automatically generates a mobile version of each website. Storage is unlimited, but the service restricts individual file sizes. Consumers are given the option to have any url ending in .weebly.com, .com, .net, .org, .co, .info, or .us. (example.weebly.com)

Android and iPhone apps are available that allow users to monitor their website traffic statistics, update blog posts and respond to comments, and add or update products if the user has an e-commerce online store. Basic features for blogging and e-Commerce are supported: site owners can develop simple stores with payments through either PayPal, Stripe or Authorize.net. Users can choose to incorporate advertisements in their pages, and visitor statistics can be tracked through an in-house tracking tool or Google Analytics.

Weebly is offered in 15 languages: English, French, Spanish, Italian, German, Portuguese, Polish, Norwegian, Dutch, Danish, Swedish, Chinese, Japanese, Russian and Turkish.

A new version was released on October 1, 2015. Named Weebly Carbon, it enabled users to add plugins into their websites among other features.
