The following are not listed in any particular order or preference. It is random just to show you what is out there for helping you build your own website.
Wix is the fast becoming the most popular in 2021. There are over 100 million sites already built and it has tons of tools and functionality to build almost anything.
Weebly definitely comes in under Wix and Squarespace as it does not have as many users as of yet. So far as of 2020, they probably have around 55 million websites created so far. One strong point about these guys is that they offer unlimited storage.
Duda has about 10 million+ websites built so far and growing! It is very design-centric, meaning it is perfect for those that are into good design over all. You should definitely check them out before you make a decision.
GoDaddy is known for their famous and funny superbowl commercials but for a good reason. They provide a full range of services, including website builders (not to mention also domain hosting too). They are a well known name and their customer service is decent.
WordPress is our absolute favorite still. You can sign up for as little as $5 a month and you can use many cool templates for your design.
Want to sell products like digital goods or music? Then this is probably the best deal out there for you. It is very similar to Wix but overall they have a larger user base and seem to be much easier to configure.
