At face value this seems like it could apply to a bunch of different categories (e.g., another text editor, another todo list, another chat app, etc...)? Yes, most new software in every category fails, but every once in awhile one succeeds, and that's how we make progress. The failures along the way just seem like a necessary byproduct of progress.

Well maybe you're not the target market then? It looks like a no-code rather than low-code effort, and I'm hazarding a guess that you're a dev and so ...

I'm sure that you didn't.
Here's the thing: this is a "Show HN" - somebody has been brave enough to show their new thing to the community. People vary - some are much more sensitive than average, particularly in a community like this that self-identifies as not-average, and will take the mildest criticism very personally.
If something's not for you, there's always the option of not commenting, or at least starting out by saying something encouraging to soften the blow.
