Wappler is not a no-code tool. You need to understand front-end & back-end & servers & then some more to make use of its amazing capabilities. From a programming language/toolkit point of view, I would suggest to take courses outside of Wappler and try to learn HTML, CSS, Bootstrap, Data Structures & Logic Building, JavaScript, SQL & Git.
Wappler is just a tool that lets you use all of the above and more - in a fast, powerful & visual way.
You will not be able to use Wappler’s full capabilities unless you really understand the basics of how all of it works. Don’t need to be an expert, but need to know the basics.
From what I know, platforms like Webflow & Bubble are no comparision to what one can do in Wappler. But its also true that such tools are very mature and have its perks. They also cater to a different target audience than Wappler.
One thing I envy is other such platforms/tools which have Dedicated Support. This is where your question about “what happens when something goes wrong” comes in. With Wappler, you only have community. You might get a reply in a minute or a week. There have been cases where I had to change my logic because of delays in fixing certain issues in the past. So our strategy has been to not update Wappler immediately to minimize such situations, and wait a few days or even few updates before updating. But never more than 3 versions.
Good thing is Wappler does not update anything automatically. So you are always in control. And with Git, you can control the updates Wappler pushes to your project files as well.
With version 3, Wappler has been really improving the balance between bug fixes & new features.
With version 4, overall product has grown a lot with even more powerful features.
As you say that you are just a designer, there is a huge learning curve ahead of you if you want to use Wappler as your primary development tool. If you are trying to assess if Wappler is the right fit for you with this and other posts, only way to actually know that is to invest for a couple of months & start using it. You will learn nothing in 7 day trial… give it at least two months… since you don’t come from a programming background.
Hope this helps.
