Codebase-aware AI assistant built on Sourcegraph's code search — the strongest tool for massive monorepos.
Sourcegraph Cody pairs AI coding assistance with Sourcegraph's world-class code intelligence — giving it contextual understanding of your codebase at a depth other tools can't match. For teams working on large monorepos, multi-repo environments, or codebases where understanding cross-repository dependencies is critical, Cody's Sourcegraph-powered context makes it significantly more accurate than AI tools with superficial codebase indexing.
Sourcegraph Cody is the AI coding assistant built into the Sourcegraph ecosystem. Sourcegraph is an enterprise code intelligence platform used by some of the largest engineering organizations in the world — Uber, Lyft, Dropbox, Cloudflare — for code search, navigation, and cross-repository analysis at scale. Cody leverages this code intelligence infrastructure to provide AI assistance that is genuinely grounded in the full codebase context — including cross-repository dependencies, API usage patterns across the organization, and semantic code search results — rather than just the files open in the editor. For engineering teams working on large monorepos (millions of lines of code) or multi-repo environments where AI tools typically lose context, Cody's Sourcegraph-backed understanding is a meaningful differentiator. Cody provides inline completions, chat, command execution, and code editing in VS Code and JetBrains. The free plan on sourcegraph.com provides basic Cody access for individual developers. The Pro plan at $9/user/mo is for individuals needing advanced chat and completions. The Enterprise plan, priced for organizational deployment, connects Cody to the full Sourcegraph code intelligence infrastructure for maximum codebase awareness. For teams already on Sourcegraph for code search, Cody is a natural AI coding extension. For teams not on Sourcegraph, the setup investment is higher but pays off on large codebases.
For codebases with millions of lines across hundreds of packages, standard AI tools either run out of context window or make suggestions that don't account for existing internal APIs and patterns. Cody's Sourcegraph-backed indexing maintains semantic understanding of the entire monorepo — asking 'How does our payment processing flow work?' returns an answer grounded in actual cross-service relationships, not a generic response.
In multi-repo environments, understanding how a shared library is used across 50 different services, or how a breaking API change propagates through the organization's codebase, requires the kind of cross-repository intelligence Sourcegraph was built for. Cody extends this intelligence to AI assistance — 'What services depend on this function?' or 'How is this configuration used across repos?' get accurate, grounded answers.
No — Cody's free and Pro plans work on sourcegraph.com without running your own Sourcegraph instance. However, the full codebase intelligence advantage (cross-repo context, massive monorepo support) requires Enterprise deployment with your own Sourcegraph instance connected to your code hosts.
For standard codebases, they're comparable. For very large monorepos or multi-repo environments, Cody's Sourcegraph-backed context provides meaningfully more accurate, grounded answers. GitHub Copilot Chat is limited by what's open in the editor; Cody with full Sourcegraph integration understands the entire codebase semantically.
