I have been looking for a long time, for a no-code solution with a self-hosted option. I have trialled many options with varying degrees of success and satisfaction, and this is by far the most comprehensive and customisable solution I have found. The support is excellent, responses are within hours, and the team work with you until your issue/question is resolved. The pricing structure is fair, and not the standard "per user" found in similar products. This makes it a much more affordable robust solution for small businesses or teams to implement and use. The learning/training tools are very helpful and cover all aspects of the product. Review collected by and hosted on G2.com.
The extensive customisability makes it a fair bit harder to learn, but the training tools and videos help immensely. Review collected by and hosted on G2.com.
