How AI is used
4D is a full-stack development environment designed for creating business applications. It provides tools to manage data models and business rules, supporting deployment across desktop, mobile, and web platforms.
The platform is intended for developers, independent software vendors (ISVs), and software publishers who build native applications for macOS, Windows, iOS, and Android. It includes an object-relational data access system called ORDA, which is designed to map data to real-world concepts.
Version 4D 21 LTS introduces AI capabilities through Vibe Coding, which supports the use of natural language prompts for prototyping and debugging. This may help reduce manual effort during the early stages of application development.
Buyers should confirm the specific user minimums and additional costs for web servers and user extensions when planning their budget, as these impact the total monthly cost.
