If you're looking for a simple and free way to create a website, Google Sites is a great option. It's easy to use, integrates with other Google products, and is responsive on all devices. However, if you need a website with a lot of features or you want to have more control over the design, you might want to consider a different website builder.
Google Sites is the Google Workspace intranet-building solution, which also happens to be great for designing simple websites. I've been using the product for 13 years and I've built thousands of sites. Like any no code web platform it has its limitations, but it works especially well at bringing together Google apps for clean company intranets, wikis and free sites. Google Sites is legitimately the only completely free website builder, with free hosting included!
