Simplify and Standardize Your Software Development Process

What is Gears?

Gears is a software development framework that defines a standard way for components to communicate through formal interfaces.

Gears uses a component-based architecture to promote rapid development by building applications from self-contained systems and having them communicate via formally defined interfaces. This allows functionality to be reused and avoids the complexity of tightly coupled systems.

Gears Studio Overview

Gears Studio is a development environment to facilitate the development of products, components, and APIs within a framework intended to avoid common pitfalls and to automate common tasks encountered in software development.

Create Products

Choose components that will help you accomplish your goals. Gears Studio simplifies the process of organizing components into a cohesive group that will serve as the foundation of your application.

Generate Components

Spend more time writing code. Gears Studio will quickly generate the framework for your components so you don’t have to.

Write APIs

Build a comprehensive API that exposes your component’s functionality. Using Gears Studio’s API editor, define formal interfaces for your components.

Build Server Integration

Set up a build server to build, test, and share components. The benefits of Gears Studio are bolstered when used in conjunction with continuous integration tools.

Community Edition vs Professional Edition

Bohemia Interactive Simulations provides a baseline unlicensed product, Gears Studio Community Edition, that provides everything required to streamline the development of Gears Products. Gears Studio Professional Edition is an extended product, requiring a license, that adds support for code signing and JFrog Artifactory integration.

Why Gears

The Gears framework and its companion tool Gears Studio were created to prevent common pitfalls and to automate common tasks encountered in software development.

Gears provides the advantages of a component-based architecture while Gears Studio automates tasks to facilitate its implementation.

Created by Developers for Developers

Developed by Bohemia Interactive Simulations, a global developer of advanced training and simulation software, Gears is being used extensively in the company’s current development efforts and is being considered for recommendation as a “modular game architecture” standard by both NATO and DoD.
