description: CodeRabbit is AI-powered code reviews built for modern development teams
77

As developers, we understand the critical value of code reviews - they're the backbone of maintaining code quality and knowledge sharing across teams. But let's be honest about the growing challenges: as codebases expand and development velocity increases, traditional code reviews often become a bottleneck. This is where CodeRabbit comes in, not to replace human reviewers, but to make their work more impactful and helpful.

### Deep Understanding, Immediate Insights

# Why CodeRabbit?

13-
Think about how you approach reviewing a complex pull request. You first try to understand the context, examine potential edge cases, and consider architectural implications. CodeRabbit performs this same thoughtful analysis, but delivers insights within minutes of PR submission.
14+
Looking back at CodeRabbit's journey, our fundamental reasons remain unchanged:

For example, when examining a change to your authentication system, CodeRabbit doesn't just flag syntax issues - it analyzes the entire authentication flow, identifying potential security vulnerabilities in token handling or session management specific to your implementation:
16+
1. **To build the best code review experience in the tech**
17+
18+
> This continues to be our core mission. It was clear to us then, as it is now, that development workflows are becoming increasingly complex — and teams need intelligent automation to maintain quality while moving fast.
19+
20+
2. **In an ever-evolving tech space, we believe AI-powered code review is the future**
21+
22+
> Just like Git revolutionized version control and CI/CD transformed deployments, we believe AI-assisted code review will become the standard for quality assurance.
23+
24+
3. **An insight that modern code review can be reimagined**
25+
26+
We call this approach _contextual analysis_, which allows us to understand not just the code changes, but their implications across your entire codebase. This enables us to provide insights about:
27+
28+
- Security vulnerabilities
29+
- Performance impacts
30+
- Architectural changes
31+
- Best practices
32+
- Knowledge sharing
33+
34+
4. **The conviction that our AI can provide a better Developer Experience (DevX)**
35+
36+
Features such as:
37+
38+
- Instant analysis
39+
- On-demand Reports
40+
- Review Instructions
41+
- CodeRabbit Commands
42+
- PR summary on the fly
43+
- Visual diagrams
44+
- Docstrings (Beta)
45+
- Custom review rules
46+
47+
> All these features improve the developer experience by reducing review time, maintaining consistency, and sharing knowledge effectively across teams.
48+
49+
These are CodeRabbit's foundational principles, but given the many _code review tools_ available today, let's explore why **you** should choose CodeRabbit:

Let the AI learn and grow with your team.
104+

Being an adaptive system means that CodeRabbit continuously learns from your team's practices and preferences without requiring manual configuration or rule setting. When reviewers accept or reject suggestions, CodeRabbit learns and applies these preferences to future reviews.

What makes CodeRabbit truly valuable is its ability to learn and adapt to your team's codebase, practices, and standards. It doesn't just pattern match - it builds a deep understanding through direct interactions with your team. For example, when a reviewer indicates a preference:

The current implementation processes each tool creation sequentially. Consider using Prisma's `createMany` for better performance. This batch operation can significantly reduce database round trips and improve overall execution time.
