Help to decide: Landing page tool without online editor, is it worth it?

Hi,

I was using Unbounce previously, the tool is great, but being forced to use online editor - really annoying.
Also, you have no control over your HTML and CSS: you can’t extend it the way you want, online editor limits you.
This is classical vendor lock - if you decide to move to another landing page tool you can’t export and import.

So I decided to build my own tool.
No online editor - just upload your HTML, JS and CSS and it is working.

Hosting, A/B split testing and analytics - all included.

What do you think about the idea? Is it worth implementing?

I would really appreciate if you answer two questions:

  1. Why would you use it?
  2. Why wouldn’t you use it?
