Sourcegraph Cody: Your AI Partner for Large Codebases
Why Big Code Is So Hard
If you’ve ever joined a large project, you know the pain.
Hundreds of repos. Thousands of files. Years of legacy logic wrapped in tech debt.
Finding where to change code can take longer than writing it.
That’s why Cody exists — it’s your AI-powered code companion built specifically for massive, real-world repositories.
Unlike most AI assistants that only “see” one file at a time, Cody understands your entire codebase, across languages and services.
It doesn’t just autocomplete — it explains, searches, and refactors.
It’s like having a senior engineer who knows everything about your company’s code — available 24/7.
What Makes Cody Different
🔍 Code Search at Scale
Built on Sourcegraph’s world-class search engine, Cody can instantly find where a function is used, how a variable flows, or where dependencies are defined — across millions of lines of code.
No more scrolling endlessly or guessing what’s connected to what. Just answers in seconds.
💬 AI-Powered Explanations
Stuck on confusing legacy code? Ask Cody.
It explains what a function does, why it exists, and how it connects to the rest of the system — in natural language.
Perfect for onboarding new devs or digging into inherited projects.
🧩 Guided Refactoring
Refactoring used to be risky. Cody makes it safer.
It maps dependencies, highlights potential impacts, and suggests changes with confidence.
You can modernize old systems without fear of breaking production.
🤝 Team Collaboration
Cody isn’t just for individuals — it’s for teams.
During code reviews or architecture discussions, you can ask Cody to validate design choices, generate documentation, or summarize code changes.
It keeps everyone aligned and informed.
🚀 Always Learning
Cody learns from your repositories and scales with your projects.
As your codebase grows, Cody grows smarter — continuously refining its understanding of your architecture, frameworks, and style.
Why Teams Love Cody
