For years, we have to use the third-party Websites to let our employee/colleges to create/modify surveys and forms, so later our users/clients will be able to fill these surveys/forms.
We have all pieces, so you will be able to create the Survey management solution exactly for your needs. Running surveys and Editor will look as you need them look. Those question types that you do not need will be removed from Editor Toolbox, custom question types, that only you need will be available for your users. You may even customize Editor Toolbox for differently for different types of your user. You may add new properties into question types or remove/hide the existing. Customize Property and Question Editors and so much more.
Do not be afraid to create YOUR OWN Survey management solution. Many of our SurveyJS Editor customers have already built them. We helped dozens companies to make it happens. It is not a rocket science, since the hardest part has been already implemented and it is their as open-source libraries.
If you come back on this page in several weeks, you will be able to see the examples of Survey management systems built on different server developer platforms.
