Cody vs GitHub Copilot

Sourcegraph Cody and GitHub Copilot both bring AI into your editor, but they approach the problem from different angles. Cody leverages Sourcegraph's code intelligence to understand your entire codebase, while Copilot focuses on fast inline completions.

Overview

Sourcegraph Cody is an AI coding assistant that uses Sourcegraph's code graph to provide context-aware answers about your codebase. It can search across repositories, understand code relationships, and answer questions about unfamiliar code. Cody supports multiple LLMs including Claude and GPT-4. GitHub Copilot provides AI-powered code completions, chat, and pull request features inside your IDE. It is tightly integrated with the GitHub ecosystem and powered by OpenAI models.

Key Differences

Codebase understanding: Cody's killer feature is deep codebase awareness powered by Sourcegraph indexing. It can answer questions like "where is this function called?" or "how does authentication work in this repo?" across your entire codebase. Copilot's context is limited to open files and nearby code. Multi-repo search: Cody can search and understand code across multiple repositories simultaneously. Copilot works within a single project context. Model choice: Cody lets you choose between Claude, GPT-4, and Mixtral models. Copilot uses OpenAI models exclusively. Completions speed: Copilot's inline completions are faster and more polished as completions are its primary focus. Cody completions are improving but chat and codebase Q&A remain its strengths. Platform integration: Copilot integrates deeply with GitHub (PR summaries, Actions, CLI). Cody integrates with Sourcegraph's code intelligence platform, which some large enterprises already use.

Pricing

Cody offers a free tier with generous usage limits and a Pro plan at $9/month. Enterprise pricing is custom. Copilot Individual is $10/month, Copilot Business is $19/month per user.

Verdict

Choose Sourcegraph Cody if you work across large or multiple codebases and need an AI that deeply understands your code architecture. Choose GitHub Copilot if you want the fastest inline completions and tight GitHub ecosystem integration.
