4D review
A paid, integrated environment for building 4D database and web applications.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
4D is an integrated development environment for building business applications across desktop, web, and mobile environments. It brings together a code editor, database and structure tools, debugger, web server, REST server, runtime, compiler, and application builder. Teams working in 4D can use it for application development, deployment packages, web interfaces through 4D Qodly Pro, and mobile projects generated from a project workflow.
According to the vendor’s pricing statement, 4D starts at $30 per user per month with monthly billing. There is no free plan. The published pricing information supports a straightforward entry point, but buyers should assess the paid commitment against their team size and development requirements. The platform’s broad scope may suit teams that want coding, debugging, building, deployment, and testing tools in one environment rather than separate products.
Its ecosystem supports OpenAI APIs, Microsoft Graph, Google Workspace, REST APIs, SQL data sources, GitHub, and GitLab. Developers can connect projects to source-control systems, manage components, plug-ins, and dependencies, and use the tool4d command-line utility for CI/CD scripts and automatic unit tests. The integrated debugger includes tracing, breakpoints, watch panes, and remote debugging, while the built-in servers support web and REST application patterns. Choose 4D when your team is building database and web applications in the 4D environment and values an integrated toolchain. Teams seeking a free development environment or a narrower tool focused on a single development task may prefer another option.
