As someone who's done this before, the value is all in that experience and finding those gaps that you didn't know existed.
One important gap I originally didn't know about was needing a market for my product idea. I thought just because I had a clever idea that it would sell! Turns out that's not the case most of the time.
And in this case, I don't think there's a market for no-code solutions that simultaneously require HTTP API integration (that's not no-code, that's low-code), when there is a really simple low-code solution that doesn't require a network round-trip.
Again, kudos on completing the exercise of releasing something! It's a step most developers don't take, and absolutely worth the experience no matter where it goes.
