About diffray

Imagine you're a developer, finally finishing a feature. You open a pull request, hoping for a smooth review, but instead, you're greeted by a wall of AI-generated noise. Generic suggestions about variable names, style nitpicks you've disabled in your linter, and a complete miss on the critical security flaw you accidentally introduced. This was the reality of single-model AI code review—a tool of speculation that created more work than it saved. diffray was born from a simple belief: code review shouldn't be a chore of sifting through false alarms. It should be a focused investigation.

diffray is a multi-agent AI code review platform that transforms how engineering teams ship quality code. Instead of relying on one generic AI to guess at everything, diffray deploys a team of over 30 specialized agents. Each agent is an expert detective in a specific domain: one hunts for security vulnerabilities, another optimizes for performance, while others are dedicated to finding bugs, enforcing best practices, checking SEO, and more. This architectural shift is profound. Because each agent investigates with purpose and context, diffray delivers what others can't: actionable, precise feedback that respects your time. The result? Teams cut their PR review time from an average of 45 minutes to just 12 minutes per week, while catching 3x more real issues with 87% fewer false positives. It's for every developer and team tired of AI noise and ready for intelligent, codebase-aware analysis that feels like pairing with an expert senior engineer on every commit.

Features of diffray

Multi-Agent Architecture

At the heart of diffray is a symphony of specialized intelligence. Unlike single-model tools that make broad guesses, diffray employs over 30 dedicated agents, each trained to be a master in one specific area. You have a security agent that deeply understands OWASP top ten and dependency vulnerabilities, a performance agent that spots inefficient loops and memory leaks, and a best-practices agent versed in your framework's idioms. This means feedback isn't generic; it's the precise, expert opinion you need for each unique aspect of your code, turning a scattergun approach into a targeted investigation.

Full Codebase Context Awareness

diffray doesn't just look at the diff in isolation—it investigates your entire repository. This context is everything. It allows diffray to catch issues that are invisible to other tools, like detecting that you're adding a duplicate utility function when one already exists, spotting a new library that conflicts with your established tech stack, or identifying call sites that break due to a function signature change. It remembers your team's past decisions and the architecture of your project, ensuring suggestions are relevant and actionable, not theoretical.

Clean, Actionable Feedback

The days of emoji spam and vague, unhelpful comments are over. diffray is built for developers who value clarity and efficiency. Every comment it leaves is clean, professional, and directly actionable. It provides concrete file paths, line numbers, and clear explanations of the why behind a suggestion. The feedback is so precise that developers act on it 98% of the time. It's designed to integrate seamlessly into your workflow, giving you the signal you need without the distracting noise.

Seamless Platform Integration

Getting started with intelligent code review takes just minutes, not days. diffray integrates directly with the tools you already use, starting with GitHub (and GitLab, Bitbucket, and on-premise solutions). You sign in with your GitHub account, install the diffray app, and choose which repositories to enable. There's no complex configuration or infrastructure to manage. It's a frictionless setup that immediately begins providing value, offering a free tier for open-source projects and a full 14-day trial for private repos to start the journey.

Use Cases of diffray

Accelerating Pull Request Reviews for Fast-Moving Teams

For development teams under pressure to ship features quickly, lengthy PR reviews become a major bottleneck. Junior developers wait for senior eyes, and context-switching eats into productive time. diffray acts as a first-line, expert reviewer available 24/7. It automatically scans every PR, catching critical bugs, security issues, and performance anti-patterns before human review even begins. This allows senior engineers to focus on high-level architecture and logic, trusting diffray to handle the foundational checks, ultimately cutting average weekly review time by over 70%.

Enforcing Code Quality and Consistency at Scale

As engineering teams grow, maintaining a consistent codebase and upholding quality standards becomes a monumental challenge. Style guides drift, and different patterns emerge across squads. diffray's specialized agents act as persistent guardians of your codebase standards. The best-practices agent ensures consistent patterns, the duplication agent finds and suggests consolidation of similar code, and the type-safety agent prevents schema drift. This creates a self-documenting, self-enforcing quality gate that scales with your team.

Proactive Security and Reliability Hardening

In industries like fintech, SaaS, or healthcare, a single bug or vulnerability can have catastrophic consequences. Traditional security scanners often run outside the development loop. diffray brings security investigation directly into the PR, where fixes are cheapest. Its security agent proactively hunts for SQL injection risks, insecure dependencies, non-atomic database operations, and concurrency issues as code is written. This shifts security left, transforming it from a final audit checkpoint into an integrated part of the developer's daily workflow.

Onboarding and Upskilling Development Talent

Onboarding new engineers onto a large, complex codebase is a slow and resource-intensive process. diffray serves as an always-available mentor. As a new developer submits their first PRs, diffray provides immediate, contextual feedback that aligns with the team's established patterns. It points out existing utilities they could reuse, explains project-specific conventions, and catches common beginner mistakes. This accelerates the onboarding journey, builds confidence, and helps new team members contribute production-ready code much faster.

Frequently Asked Questions

How is diffray different from other AI code review tools?

The difference is foundational. Most tools use a single, general-purpose AI model that tries to do everything at once, leading to generic, often noisy feedback. diffray uses a multi-agent system where over 30 specialized AI agents, each an expert in a domain like security or performance, work together. This allows for deep, investigative analysis of your code within the full context of your repository, resulting in far more accurate, relevant, and actionable findings instead of speculative guesses.

Does diffray store or have access to my private source code?

No, diffray is built with security and privacy as a core principle. Your source code is never stored on diffray's servers. The analysis happens in a secure, ephemeral environment where the code is processed for the duration of the review and then discarded. diffray is also SOC 2 compliant and GDPR ready, ensuring enterprise-grade data handling for all teams, from startups to large corporations.

What if I disagree with a suggestion or it's not relevant to my project?

You are always in control. diffray is designed to be a collaborative assistant, not an authoritarian gatekeeper. You can easily dismiss any comment with a single click. Furthermore, you can configure which specialized agents are active on a per-repository basis and customize guidelines to match your team's specific coding standards and architectural decisions, ensuring the feedback is always relevant.

How long does it take to set up and see results?

Setup is designed to be virtually instantaneous. You can sign in with your GitHub account and install the diffray GitHub app in just a few clicks. Once you enable it on a repository, it will automatically analyze the next pull request you open. You'll see your first intelligent, multi-agent review comments within minutes, with no complex configuration or credit card required to start the free trial.
