About diffray

diffray is a revolutionary AI-powered code review platform designed to transform how development teams ship quality software. It moves beyond the limitations of generic, single-model AI tools that flood pull requests with noisy, irrelevant feedback. Instead, diffray employs a sophisticated multi-agent architecture, where over 30 specialized AI agents—each an expert in a specific domain like security, performance, bug detection, best practices, or SEO—work in concert to investigate your code changes. This targeted approach allows diffray to understand not just the diff, but the full context of your repository, leading to profoundly more accurate and actionable insights. The result for teams is a dramatic reduction in review fatigue and a significant acceleration in development velocity. Developers spend less time sifting through false positives and more time fixing genuine, critical issues. diffray is built for engineering teams of all sizes who are frustrated with the inefficiency of current AI review tools and are ready to experience intelligent, context-aware automation that truly augments their workflow, cutting PR review time and boosting code quality with every merge.

Features of diffray

Multi-Agent Specialized Intelligence

diffray's core innovation is its fleet of over 30 specialized AI agents. Unlike a single, generalized model that tries to do everything moderately, each diffray agent is a dedicated expert. You have agents solely focused on uncovering security vulnerabilities, others that hunt for performance anti-patterns, and more that specialize in catching bugs, enforcing best practices, or optimizing for SEO. This division of labor ensures deep, investigative analysis in each category, transforming code review from superficial speculation into a thorough audit.

Full Codebase Context Awareness

Traditional tools often review a pull request in isolation, leading to generic or irrelevant suggestions. diffray breaks this pattern by understanding your entire repository's context. It analyzes the existing codebase to spot duplicates, recognize established patterns, and identify inconsistencies that a simple diff would miss. This means it can catch issues like adding a redundant library, drifting type definitions, or logic that contradicts prior architectural decisions, providing feedback that is genuinely relevant to your project.

Clean, Actionable Feedback

Tired of emoji spam and vague comments? diffray is engineered for professional workflows. It delivers clean, concise, and highly actionable feedback directly in your pull requests. Comments include specific file paths, line numbers, and clear explanations of the issue and its impact. The system is designed to provide findings you can immediately act upon, such as pointing out exact call sites that need updating after a function change or identifying specific tests with empty assertions.

Effortless Integration & Setup

Getting started with intelligent code review should not be a chore. diffray is built for seamless integration into your existing workflow. You can sign in with GitHub in one click, install the GitHub app on your organization or personal repositories, and be up and running in minutes. It offers full control over which repositories are enabled and allows for customization of review settings and agent preferences, putting you in charge of the review process from the very beginning.

Use Cases of diffray

Accelerating Pull Request Review Cycles

Development teams bogged down by lengthy manual review processes can use diffray to dramatically cut review time. By automatically surfacing critical security flaws, performance bottlenecks, and logical bugs with high accuracy, diffray allows human reviewers to focus on higher-level architecture and design discussions. Teams report reducing weekly PR review time from 45 minutes to just 12 minutes, unlocking significant productivity gains and faster release cycles.

Enforcing Code Quality and Consistency

For tech leads and engineering managers, diffray acts as a tireless enforcer of code standards and best practices. Its codebase-aware agents prevent duplicate utility functions, catch type definition drift across files, and suggest shared schemas for validation logic. This ensures the codebase remains clean, maintainable, and consistent as the team grows, reducing technical debt and onboarding time for new developers.

Proactive Security and Reliability Auditing

Security-conscious teams in sectors like fintech or healthcare leverage diffray's specialized security agent to catch vulnerabilities that generic tools miss. It can identify non-atomic database updates that risk data inconsistency, spot potential SQL injection vectors, and find concurrency issues that could lead to race conditions. This proactive, automated audit provides an essential safety net for every code change.

Improving Test Suite Effectiveness

diffray helps teams build more robust software by analyzing test code. It can identify "meaningless tests" that exist but contain no real assertions, ensuring your test suite provides genuine value and coverage. It also checks if code changes break existing tests or if new functionality lacks proper test coverage, guiding developers to write more effective and reliable tests.

Frequently Asked Questions

How is diffray different from other AI code review tools?

diffray fundamentally differs through its multi-agent architecture. While other tools use one generic AI model for all tasks, leading to noisy and often irrelevant feedback, diffray employs over 30 specialized agents. Each agent is an expert in a specific domain like security or performance, and they investigate your code with full repository context. This results in far fewer false positives, catches more real issues, and delivers actionable, context-aware feedback instead of generic speculation.

Does diffray store my source code?

No, diffray is built with privacy and security as a priority. Your source code is never stored permanently. The system processes code temporarily in memory to perform the analysis and generate feedback for your pull request, but it does not retain the code after the review is complete. This approach is aligned with stringent security standards.

Can I customize which agents review my code?

Yes, you have full control over the review process. During the setup and configuration of your repository, you can choose which specialized agents to enable or disable based on your project's needs and your team's priorities. This allows you to tailor the review focus to what matters most for your specific codebase.

Is diffray free to use?

diffray is completely free for open-source projects. For private repositories, diffray offers a 14-day free trial with no credit card required to start, allowing you to experience the full benefits on your own codebase. After the trial, you can choose a plan that fits your team's size and needs.
