Very powerful in the back-end, with room for improvement in the front-end
I am passionate about the no-code and low-code solutions out there and I can say Directual is a great addition to this landscape.
The way Directual handles the back-end is a breeze of fresh-air compared to other competitors and I hope it allows me exceed some of the limitations found in other tools (e.g. implementation of complex logic, exposure of APIs), thus I encourage you to give it a try to check if it helps your use cases.
Regarding the front-end, it is very fast to implement yet it lacks some of the features required to build an entire app solely relying on Directual (which would be my dream!). I hope the Directual team continues working on this area and making it even better.
For now, the fact that they have agreed on adding the much needed white-labelling to the Sumoling buying this deal is already a good signal, keep it like that!
