Are there any free alternatives to Setka/Udesly?

I found these from the integrations section of Ghost and found them to be easy to use to design a custom ghost blog pages or posts but they are not affordable to everyone. Are there any free alternatives to Setka/Udesly?

I can always tinker with HTML and CSS but I want a easy drag and drop builder like Elementor or Setka/Udesly.

I wish the built in editor had support for content alignment, adding column blocks, text overlay over header images.

@DavidDarnes Any suggestions on this?
