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.

How does diffray handle monorepo complexity?

diffray analyzes your monorepo structure — whether Turborepo, Nx, Lerna, or pnpm workspaces — and understands package boundaries. When you change shared code, it identifies all affected packages and flags potential breaking changes.

Can it detect cross-package breaking changes?

Yes. diffray tracks internal APIs and dependencies between packages. If you change a function signature in a shared library, it flags all packages that import that function and might break.

Does it work with Turborepo and Nx?

Absolutely. diffray integrates with popular monorepo tools and understands their dependency graphs, task pipelines, and caching strategies. It can even suggest which packages need testing based on changes.

How does it maintain consistency across packages?

The Consistency agent enforces shared conventions across all packages — naming patterns, folder structure, dependency versions. Your monorepo stays cohesive even as it grows.

Monorepo Growing Pains

The bigger it gets, the harder it gets

Blast Radius Blindness

Change one file, break 5 packages. No way to know which packages depend on shared code until something breaks.

Inconsistent Standards

Each package evolves differently. Different linting rules, different patterns, different quality levels.

Review Complexity

PRs touch multiple packages. Reviewers need expertise in all areas, or issues slip through.

Dependency Hell

Internal package versions drift. Breaking changes propagate silently. Integration issues surface late.

AI That Understands Your Monorepo

diffray analyzes your workspace structure and provides context-aware reviews

Cross-Package Impact Analysis

When you change shared code, diffray maps every package that depends on it and flags potential breaking changes.

"This change affects @app/ui, @app/forms, and @app/dashboard. Consider the impact on form validation."

Boundary Enforcement

Define which packages can import from which. Prevent coupling creep and maintain clean architecture.

"@app/core should not import from @app/web. This creates a circular dependency risk."

Consistent Standards

Apply team conventions across all packages. Same quality bar everywhere, regardless of package age.

"This package uses default exports, but team standard is named exports. See @app/components for examples."

Smart Test Suggestions

Know which packages need testing based on changes. Don't waste CI time testing unaffected code.

"Changes to @shared/utils affect 12 packages. Recommend running tests for: @app/auth, @app/payments."
