Otherwise you would not be asking but telling us.

There is NO BEST no-code web app tool as what makes it best varies with each person. But in your case, Silconmint didn't make the cut.

Can you tell us why it didn't?

https://sourceforge.net/software/no-code-development/?feature_no-code-development=Web+%2F+Mobile+App+Development has a top-74 for open source no-code web or mobile app tools. Alas, you need to read the descriptions to see how many are for web apps and how many for Android/iPhone.
Of course, there are a lot of not-open-source tools also.

It might take some time to find the best for your next project. And it doesn't seem unlikely that for your second project another one is best.
Maybe settle for "good enough"?

It might be useful to read through a few of our editorial articles about it. Find them with by googling for NO CODE WEB APP SITE:TECHREPUBLIC.COM

No-code” doesn’t really mean no-code. In fact, there is coding, and that is the coding the people who developed the tool did. However, for an easier and cheaper experience for the user of the tool (meaning most businesses today), all you need to do is click, scroll, and/or drag and drop.

Thus, the process of coding and programming is made more accessible for the masses and a new era of technology has arrived.
