I have seen appsmith and tooljet in the space. Played around with them for a while. What I am super scared of is pricing. Though it is free and opensource. I love that, moment you ask me to pay. I am going to opt Retool as it is more enterprise ready from perception wise. Even superblocks that cloned and copied appsmith, I am willing to pay for them as there is trust of some sorts as they have certain upfront pricing. Not having upfront cost can. be very deceptive.
