Most people who have used this product haven't really tried the alternatives so I don't really think that Pilot is better than the others, just different in that Pilot uses Javascript as a scripting language, is easy to setup, and is Open Source.

But https://www.retool.io, https://bubble.io/, Mendix, Outsystems, Oracle Apex are all much better paid options than Pilot

And https://www.lazarus-ide.org/ is probably a better Open Source option

Anyway, it is still very early days for this tool, so still a long way to go
