Mobirise offers many site blocks in several themes, and though these blocks are pre-made, they are flexible. You can combine blocks in different ways on your pages.
Mobirise gives you the freedom to develop as many websites as you like given the fact that it is a desktop app.
Publish your website to a local drive, FTP or host on Amazon S3, Google Cloud, Github Pages. Don't be a hostage to just one platform or service provider.
Just drop the blocks into the page, edit content inline and publish - no technical skills required.
