Open Source Website Builder
A website builder trades hand-coding for speed, but every drag-and-drop shortcut writes markup you don't see, and that hidden output decides whether the site stays fast, accessible, and yours to move. The open source builders here generate code you can read and host anywhere, so you keep the convenience of visual editing without surrendering the actual files your site is made of.
