Lots of power, but not enough documentation and pretty poor support. Found a bug, verified by Form.io, they offered to fix but only with payment. Already on the enterprise plan.

I asked for help about a specific functionality in building a form and support answered in a very short time with a fully working tip.

This is a great a service. The documentation to create the forms was incredibly helpful.

There was obviously a tremendous amount of work as well as planning that went to the platform. I'm a developer and, honestly, I don't know that I could have pulled this off. Looking at the source code that is available, the developer(s) have allowed for easy customization but also future design and function implementation. I should also mention the extensive safeguards that are in place with regard to security... very comprehensive.

I think Form.io is a good lib and contributes to build strong applications under low-code philosophy. Although the documentation for developers that want to contribute and extend the components is not enough and would be better.

Some of the features they claim to providing in there docs have issues and team is not fixing those. e.g in there Datetimepicker it the timezone is not working for other options it always shows in viewer timezone. Also there are issues with populating data programmatically to components. we used the same way to populate data as mentioned in the docs. And we also tried with the latest build version. Issues are still there.
