We typically do not like closed website builder platforms because they lock you in and make it harder to switch. If we had to pick one to avoid, then we’d say avoid Wix because it’s the hardest platform to switch away from. They aggressively try to upsell every step of the way.
We’ve been building websites since 1998 and have tried many platforms. For the last decade, we always favor WordPress because it’s open source and gives you full ownership of your content.
