Expand your projects to the .NET platform without discarding your existing native Delphi / Win32 code.
Hydra is an application framework for creating modular applications that mix managed and unmanaged code in one project. It supports host applications and plugins across Delphi, .NET, Java, and native Windows development, making it practical to extend existing applications, reuse established code, and combine different user interface technologies.

Modular Application Architecture

Hydra structures an application around host applications and plugins. This model lets developers split functionality into separate modules, deploy them with the main application or separately, and combine multiple parts into a single application experience.

Cross-Platform Code Integration

The framework enables one project to combine managed code such as .NET with unmanaged Delphi code, and also supports Java and native Windows code. This makes it suitable for teams that need different technologies to work together inside one application.

Host And Plugin Communication

Hydra provides an interface-based approach for exposing plugin functionality to the host application. Developers can define clear integration points, call into plugin logic, and keep communication between modules organized and predictable.

Visual Plugin Embedding

Hydra can load visual plugins that contribute user interface elements to the host application. This allows teams to place UI built with different frameworks into the same application and present it as a unified desktop experience.

Non-Visual Business Logic Reuse

The framework also supports non-visual plugins for background processing, calculations, data handling, and other shared logic. This helps developers reuse existing code without tying it directly to a specific user interface layer.

Multiple UI Technology Support

Hydra supports host applications based on VCL, FireMonkey, and WinForms, while plugins can be created with technologies including VCL, FireMonkey, WinForms, WPF, Swing, and non-visual implementations. This broadens integration options for desktop application teams.

Delphi Code Modernization Paths

Hydra is designed for scenarios where developers want to extend established Delphi applications with newer technologies or reuse proven Delphi code in newer application projects. It supports gradual evolution instead of forcing immediate rewrites.

Mixed Delphi Version Scenarios

The framework can bridge code built with different Delphi versions through its host and plugin model. This helps teams isolate code that is harder to migrate while still introducing newer Delphi-based functionality into the wider application.

Java And Native Windows Interoperability

Hydra supports Java plugins and native Windows plugins built with Elements and Island. This allows developers to integrate Java business logic, Swing interfaces, or native modules written in supported languages into Delphi and .NET host applications.
