Best Code Review Tools

In software development, reviewing your code base is essential for executing clean and healthy code and delivering a high-quality product.

That’s why code review is critical for developers throughout the SDLC. So today, you will be introduced to some of the top automated code review tools and basics.

Advantages of code review

• Detecting bugs early in the development process is more accessible than finding them during code executions and developments, saving time and money.
• Your code will comply with coding and security best practices.
• Participating in code reviews allows new developers to learn from experts.
• There is no miscommunication among teams. A code review gives the whole team a clear project picture, bringing them to the same page.
