Roast our landing page

Certainly a good start to a landing page with lots of useful information to get a viewer converted to a user, or at least trying it out. The "Try now" button didn't take me anywhere, not sure if that's just an issue for me.
As I was scrolling through the page, I noticed the translucent nav bar was slightly distracting. It's a good idea to keep it fixed so the CTA is constantly shown however I think you can keep it a solid colour.
When you're ready it may be good to attract users with testimonials. The examples you have could perhaps be enhanced to have some comments from the owners.
I didn't notice any pricing info which I think is crucial to a viewer, this could be covered either in a pricing table or even FAQs section.
I'm building a landing page tool myself so I'm keen to know which tool you used and any info you can share on your experience (what worked well, what could be improved, etc.). If you'd like to consider my tool (for free of course) then let me know and we can have a chat :)

1. You want your main heading to be the benefit. So change it to "Create a custom web app in minutes".

2. Tag line can be "Lowdefy is a no-code platform that provides you all the building blocks to create a web app."

3. To me, the site looks dull and very enterprisy. I prefer a more lively site. But it's just me.

4. A screenshot of your UI will definitely help.

5. Make sure to add testimonials if you have any.
