All these website building platforms, including Wix, Jimdo and Weebly offer a completely free login, but the secret is that you have to accept certain limitations. A free account gives you access to the majority of the features on most of the website builders, but you have tiny web space and bandwidth for your web project.
Free is not exactly free
How do you suppose a company that offers free website builder and hosting to make any money to run their operations?
The answer: Through advertising. The free website builders insert advertising into your page and you don’t have control over what advertising is shown.
