What advantage does GitLab's integration of code review and Review Apps provide to developers?

The integration of code review and Review Apps in GitLab significantly speeds up the development process by enabling a seamless workflow within one unified platform. This allows developers to collaborate on code changes and immediately see the effects of those changes in a live environment. When a developer submits a code change for review, Review Apps automatically deploy the code in a temporary environment, allowing the team to test and provide feedback instantly. This immediate access to a working version of the application reduces the cycle time for testing and feedback, leading to faster iterations.

Moreover, this integration minimizes the need for multiple tools and contexts, allowing developers to focus on their work without switching between different platforms for code review and deployment. This streamlined process ultimately enhances productivity, allowing teams to deliver features and fixes more rapidly and efficiently. In contrast, the other options either focus on narrow aspects of development or don’t directly relate to the core benefits of integrating these specific features.
