Cody

What is Cody?

Cody is the AI software development assistant created by Sourcegraph, a leading enterprise in large-scale code search. Launched in 2023, Cody's major strength is its ability to map and understand your entire local or remote codebase, offering unparalleled search context.

How it works

Cody utilizes Sourcegraph's advanced graph search engines to index entire repositories. It feeds market-leading models (such as Claude 3.5 Sonnet and GPT-4o) with the exact context of your code, generating answers that respect the architectural rules of your system.

Key features

• Full Codebase Context: Answers complex questions by reading multiple directories and related files natively.
• On-the-Fly Model Switching: Choose which AI to use in chat (Claude 3 Sonnet/Opus, GPT-4o, Gemini 1.5 Pro, or Mixtral).
• Custom Quick Commands: Shortcuts to generate unit tests, explain complex logic, or create standardized documentation.
• Smart Autocomplete: Fast multi-line code prediction integrated in VS Code, JetBrains, and Neovim.

Available integrations

Cody integrates seamlessly with:

• VS Code
• JetBrains IDEs
• GitHub
• GitLab
• Sourcegraph Enterprise

Who it is for

• Developers working in monorepos or complex and massive codebases.
• Software engineers who like to switch between different language models depending on the task.
• Teams that value open-source tools and want built-in privacy in their workflow.

Real-world use cases

1. Understanding legacy systems: Ask Cody's chat "Where are admin permissions configured?" and receive the exact file path.
2. Writing tests for complex code: Select a function full of dependencies and request a matching mocked test file.
3. Safe API refactoring: Modify API routes while ensuring corresponding calls in other files are updated.

Data and results

• Massive adoption by developers who prefer the flexibility of switching AI models.
• Significant reduction in time spent navigating old internal documentation.
• Rated as one of the most robust code context assistants due to Sourcegraph's core technology.
