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.

How long does a code review take with diffray?

diffray provides comprehensive code reviews quickly. The multi-agent system works in parallel to analyze your code efficiently while maintaining thorough analysis.

Is diffray free for open source projects?

Yes, diffray is free forever for open source projects. We support the open source community with full access to our multi-agent code review platform.

For Solo Developers & Indie Hackers

Ship Fast.
Stay Secure.

The Solo Developer's Dilemma

You move fast. But without code review, problems compound silently.

No Second Eyes

You code, you commit, you deploy. No one catches your mistakes. Bad patterns become habits. Technical debt grows invisibly.

"I spent 3 days debugging an issue that a reviewer would have caught in 30 seconds."

Security Blind Spots

SQL injection. XSS. Hardcoded secrets. You know the risks, but you're focused on features. Security issues hide until it's too late.

"My API keys were exposed on GitHub for 6 months before I noticed."

Bugs Ship to Production

Edge cases you didn't think of. Race conditions. Null pointer exceptions. Your users become your unpaid QA team.

"A critical bug hit production at 2am. I was the only one who could fix it."

The Reality of Solo Development

Code reviews before shipping

67%

of solo projects have security vulnerabilities

more bugs reach production without review

40%

of debugging time on preventable issues

The AI Coding Paradox

Cursor & Copilot Made You Faster.
But Also More Vulnerable.

You're shipping 3x more code with AI assistance. But here's what no one tells you: AI-generated code needs more review, not less.

AI Hallucinates APIs

Copilot suggests functions that don't exist. Methods with wrong signatures. Deprecated patterns.

Security Blindness

AI doesn't know your threat model. It generates vulnerable code that looks perfectly reasonable.

Subtle Bugs

Off-by-one errors. Missing edge cases. Race conditions. AI code works until it doesn't.

diffray: Your AI Code Reviewer

Use AI to write code faster. Use diffray to catch the mistakes AI introduces.

Catches AI hallucinations

Verifies that suggested APIs actually exist in your dependencies

Security-first analysis

Specialized security agent checks OWASP Top 10 on every PR

Bug detection

Finds edge cases and potential runtime errors before your users do

The smart play: AI writes your code, AI reviews your code. You ship with confidence.

Your Senior Engineer on Autopilot

diffray reviews every commit like a 10x engineer would — automatically and instantly

Security First

Catch SQL injection, XSS, exposed secrets, and OWASP Top 10 vulnerabilities before they reach production. Sleep better knowing your app is secure.

Secret detection in code & config
Injection vulnerability scanning
Authentication & authorization checks

Bug Prevention

Find null pointer exceptions, off-by-one errors, race conditions, and edge cases. Fix bugs before they become 2am emergencies.

Edge case detection
Null safety analysis
Error handling verification

Building Solo: Before vs After

Before diffray

No one reviews your code

Security vulnerabilities ship unnoticed

Bugs discovered by users in production

Bad patterns become habits

Technical debt grows silently

Debugging takes hours unnecessarily

Deploy and pray

After diffray

Every PR reviewed automatically

Security issues caught before merge

Bugs fixed before reaching users

Consistent code quality

Learn best practices as you code

Fix issues while context is fresh

Ship with confidence

Built for Solo Developers

diffray understands the indie hacker workflow

Zero Overhead

No configuration. No maintenance. No meetings. Set it up once and forget it exists — until it saves you from shipping a bug.

Signal, Not Noise

Only high-confidence issues. No nitpicking about code style. Real security vulnerabilities. Actual bugs. Things that matter.

Ship Faster

Catch issues immediately while the code is fresh. No more going back to debug problems you introduced weeks ago.

Level Up Your Skills

Every review teaches you something. Learn best practices, security patterns, and clean code — from an AI that's reviewed millions of PRs.

What Solo Devs Say

"I was leaking API keys in my code for months. diffray caught it on my first PR. That alone paid for years of subscription."

— Solo founder, B2B SaaS

"Building alone is hard. diffray is like having a senior dev on call 24/7. The security feedback alone has saved me countless hours."

— Indie hacker, ProductHunt Top 5

"I use Cursor for everything now. But AI-generated code has subtle bugs I'd never catch myself. diffray finds them before my users do. Game changer for solo devs."

— Solo founder, dev tools

"Shipped my MVP in 3 weeks. Without diffray, I would've shipped 5 security holes too. It's like having a co-founder who only does code review."

— Bootstrapped founder, fintech
