  Instant feedback from code changes enables more iterative development and faster bug detection, ultimately enhancing the quality of the software being developed.

Possible disadvantages

• Cost
  JRebel is a commercial product, which means it incurs a licensing fee that can be a drawback for startups and smaller teams with limited budgets.
• Learning Curve
  Despite being easy to integrate, new users might face a learning curve when configuring JRebel to suit their specific development environment and requirements.
• Limited to Java
  As a tool deeply integrated with Java, JRebel is not applicable to projects outside the Java ecosystem, which limits its utility for teams working with multiple programming languages.
• Complex Deployment Scenarios
  In complex application setups or large enterprise environments, configuring JRebel might require additional effort to ensure consistent performance across all integration points.
