I've tested your platform, it's really sick man, good job :D
And indeed, it asks for 24$/month after the process of creation. From the main page, it feels like it's free, moreover, you're offering a pro version so it feels like the non-pro version is free, the pro version is not.
That must explain the fact people leave the platform after seeing that.
In my opinion, you should put the pricing on your main page, so people will use it only if they agree with your pricing and you'll be able to measure it. I personnaly clicked "Start building" before seeing the pricing link at the top.
Test different things is the only way ^^
Oh, and will also appreciate a lot to have your website listed on networkup.io <3 Can add it on my own if you want but you'll be able to have notifications if you do it with your account.
May the force be with you!
