For example, someone posted https://typeprompt.com. This is a nice example of what I am looking for.

From my extensive research, there is AppSmith, Tooljet, Windmill.dev, lowcoder, Budibase available.

These tools are limited. They either limit number of users, don't provide SSO. None of them allow removal of logos even in the open source software.

Despite all no code hype and solutions, do we have anything that can put together a functional app without restrictions?

I would love to get your suggestions.
