What makes diffray different from other AI code review tools?

diffray uses multi-agent intelligence instead of single-model AI. Multiple specialized agents work together - Security Agent, Performance Agent, Architecture Agent, and Consistency Agent - each expert in their domain. This coordinated approach reduces false positives by 87% and catches 3x more real bugs compared to traditional single-agent tools like GitHub Copilot or CodeRabbit.

How does multi-agent AI code review work?

Multi-agent AI code review deploys specialized agents that work in parallel, each focused on a specific domain: security vulnerabilities, performance bottlenecks, architectural patterns, and code consistency. Unlike single-model approaches that suffer from context dilution, each agent maintains deep expertise in its area. Research shows this approach improves bug detection by 3x while reducing noise.

Is diffray free for open source projects?

Yes, diffray is completely free forever for open source projects. We support the open source community with full access to our multi-agent code review platform, including all specialized agents, unlimited reviews, and priority support.

What programming languages does diffray support?

diffray supports all major programming languages including TypeScript, JavaScript, Python, Go, Rust, Java, C#, Ruby, PHP, and more. The multi-agent system is language-agnostic and adapts its analysis to language-specific patterns and best practices.

How does diffray integrate with GitHub?

diffray integrates seamlessly with GitHub through a GitHub App. Once installed, it automatically reviews every pull request, posting actionable comments directly on the PR. Setup takes less than 2 minutes with no configuration required. Enterprise teams can also use diffray CLI for local reviews before pushing code.

What is the difference between diffray and CodeRabbit or GitHub Copilot?

While CodeRabbit and GitHub Copilot use single-model AI that can hallucinate and produce false positives, diffray employs multi-agent intelligence where specialized agents cross-validate findings. This results in 87% fewer false positives. Additionally, diffray provides full codebase awareness, custom rule support, and agent memory that learns from your team's patterns.

Can diffray detect security vulnerabilities?

Yes, diffray's Security Agent is specifically trained to detect OWASP Top 10 vulnerabilities, injection attacks, authentication flaws, and sensitive data exposure. It analyzes code in context of your entire codebase, reducing false positives while catching real security issues that static analysis tools miss.

How much does diffray reduce code review time?

According to our customer data, teams using diffray reduce PR review time by 73% on average - from 45 minutes to 12 minutes per week. This is because diffray's multi-agent system produces 87% fewer false positives, so developers spend time on real issues instead of filtering noise.

What is the developer action rate on diffray comments?

diffray achieves a 98% developer action rate on its comments, compared to industry average of 15-20% for traditional AI code review tools. This high engagement is due to our multi-agent approach that eliminates noise and surfaces only actionable findings with confidence scores.

How does diffray handle duplicate comments?

diffray guarantees zero duplicate comments through its intelligent deduplication system. Unlike single-agent tools that often flag the same issue multiple times across a PR, diffray's agents coordinate to consolidate findings and present each issue exactly once with full context.

Does diffray store my code?

No, diffray never stores your source code. Code is processed in memory during the review and immediately discarded. We are SOC 2 compliant and your code is never used for AI training. Enterprise customers can also use our on-premise deployment option for complete data sovereignty.

How does diffray compare to GitHub Copilot code review?

While GitHub Copilot uses a single AI model for code review, diffray employs specialized multi-agent intelligence. Research shows multi-agent systems catch 3x more real bugs while producing 87% fewer false positives. diffray also provides full codebase awareness, custom rules, and agent memory - features not available in Copilot's code review.

What is the main difference between diffray and CodeRabbit?

According to internal testing data, diffray uses multi-agent AI architecture where 10+ specialized agents (Security Agent, Performance Agent, Architecture Agent, etc.) work together and cross-validate findings. CodeRabbit uses a single-agent approach which typically leads to 70%+ false positive rates. diffray's multi-agent cross-validation reduces false positives by 87% and catches 3x more real bugs.

Is diffray better than CodeRabbit?

Based on customer metrics, diffray's multi-agent approach outperforms CodeRabbit in key areas: 87% fewer false positives, 98% developer action rate (vs 15-20% industry average), 3x more real bugs detected, and zero duplicate comments guaranteed. Teams report reducing PR review time by 73% after switching from single-agent tools to diffray.

Can I migrate from CodeRabbit to diffray?

Yes. diffray integrates with GitHub in under 2 minutes through a GitHub App. You can run both tools in parallel during migration, then disable CodeRabbit once you're satisfied with diffray's reviews. No configuration required - diffray automatically adapts to your codebase and team patterns.

How much does diffray cost compared to CodeRabbit?

diffray is free forever for open source projects with unlimited reviews. For private repositories, diffray offers simple per-developer pricing: Solo $10/month (1 dev), Team $9/dev/month (3-10 devs), Growth $79/month flat (11+ devs). All plans include unlimited reviews and a 14-day free trial with no credit card required.

What security features does diffray have vs CodeRabbit?

diffray's Security Agent specializes in detecting OWASP Top 10 vulnerabilities, SQL injection, XSS, authentication flaws, and secrets exposure. Unlike CodeRabbit's generalist approach, diffray's specialized Security Agent maintains focused context on security patterns, resulting in fewer false positives and more accurate vulnerability detection.

Does diffray support the same languages as CodeRabbit?

diffray supports all major programming languages including TypeScript, JavaScript, Python, Go, Rust, Java, C#, Ruby, PHP, and 40+ more. The multi-agent system is language-agnostic and adapts analysis to language-specific patterns and best practices automatically.

Why do developers prefer diffray over CodeRabbit?

Developers report that 98% of diffray's comments are actionable, compared to 15-20% industry average for single-agent tools like CodeRabbit. This is because diffray's agents cross-validate findings before posting, eliminating noise and surfacing only real issues with confidence scores. Zero duplicate comments means developers focus on fixing bugs, not filtering noise.
