# Claude Code vs GitHub Copilot

Both now reach the editor, the terminal and the cloud. What differs is where each one starts: Claude Code in a terminal next to your tests, Copilot in your editor and in GitHub's issues and pull requests.

## The two options

### Claude Code (terminal, plus cloud sessions)

An agent in your shell that can run your tests and read the failure.

Pick it if:
- You want the agent where git, tests and deploys already live
- You would rather read a diff than watch a file change under your cursor
- You want the loop closed: it edits, it runs the suite, it sees what broke

What will annoy you: The CLI is a text interface with no file tree. If the terminal is new to you, that is a second thing to learn at the same time as the agent. The same agent also ships as a VS Code extension and a desktop app, and can run a task as a cloud session that ends in a pull request — but the terminal is where it is most at home.

### GitHub Copilot (editor, GitHub and terminal)

Help that starts in the editor you already use — suggestions as you type, an agent in a side panel — and reaches into GitHub, where a cloud agent works an issue on a branch and can open a pull request for you to review.

Pick it if:
- Your team's work already runs through GitHub issues and pull requests
- You want to stay in your current editor — VS Code, Visual Studio, JetBrains and others
- You want suggestions as you type as well as an agent that takes whole tasks

What will annoy you: It is several products under one name — editor suggestions, an agent, a cloud agent, a CLI, code review — and what you get depends on your plan, the editor you use and your organization's policies, so the feature you read about may not be the one in front of you. Its instructions come from more than one file, too: .github/copilot-instructions.md for the repository, plus AGENTS.md files.

## What is the same

- Both edit files and run commands for you, within the permissions you allow
- Both can take a task to a cloud machine and come back with a pull request
- Both have a terminal agent and an editor integration — they differ in which one is home
- Both can take project instructions from an AGENTS.md in the repository

## Where does your work start: in a terminal, or in GitHub and your editor?

Copilot is spread across GitHub itself: it suggests code as you type in VS Code, Visual Studio, JetBrains IDEs and others, its cloud agent picks up work from an issue, a pull request or the agents panel, works on a branch and can open a pull request for you to review, and Copilot CLI brings an agent to the terminal. Claude Code starts in the terminal and reaches outward — an editor extension, a desktop app, cloud sessions. If your team already files and reviews its work in GitHub, Copilot meets the work where it is filed. If your day is a terminal with git and the tests in it, Claude Code is already sitting there. Either way, keep the shared rules in AGENTS.md: Copilot's agents (the cloud agent, Copilot CLI) and Copilot Chat in VS Code read it — in other editors its chat reads .github/copilot-instructions.md instead — and Claude Code reads it directly when there is no CLAUDE.md, or through an @AGENTS.md import when there is.
