4D
Fast development platform for business apps
4D is an integrated development platform for building and deploying business applications across web, mobile, desktop, and client-server environments. It combines a graphical relational database with application development tools, allowing developers to focus on data models and business rules while targeting multiple platforms from a single environment.
The platform includes ORDA for object-oriented data access, 4D Write Pro for document generation, 4D View Pro for spreadsheet-like views, and Qodly Pro for web development. It also offers an AI Kit for AI integration, Fluent UI and Liquid Glass interface components for Windows and macOS, and QUIC protocol support for connection reliability. 4D Server handles application hosting, with shared and session singleton execution support.
4D is aimed at consultants, independent software vendors, in-house developers, software publishers, decision makers, and educational institutions. It is available through a free trial, with pricing based on a per-user monthly subscription model. A maintenance program and professional services are offered separately, along with training content that is free for Silver Partners and above.
