Activating a product opens its read here. Activating the selected product opens its hub.
Each product sits on the layers it owns, placed left to right by how far its positive sources lead its negative ones. A disc's area is its sources in this view and its tone is its band. Products with fewer than 20 sources from 15 authors have no net and sit at the right, under Unscored. The teal line joins GitHub Copilot across its layers.

Stack Footprint
What is GitHub Copilot used for, and by whom?
AI Coding Agents, also listed under AI developer assistant, developer tools, and software development.
Plan
Work planning: Supports
Work planning, supports. Plan mode in the CLI and desktop app prepares an implementation plan. The cloud agent accepts issues from GitHub, Linear, or Jira. Your issue tracker keeps the planning record.
Build
Codebase context: Supports
Codebase context, supports. Copilot indexes repositories for semantic code search in chat and the cloud agent. It reads repository instructions such as copilot-instructions.md and AGENTS.md.
Coding: Core
Coding, core. This is Copilot's primary role. It writes code through completions and next edit suggestions in the IDE, agent mode, the CLI, and a cloud agent that implements an issue as a draft pull request.
Agent runtime: Core
Agent runtime, core. Developers direct Copilot through IDE extensions, Copilot CLI, the GitHub Copilot desktop app, GitHub.com, and GitHub Mobile. Sessions transfer between these interfaces.
Tool execution: Supports
Tool execution, supports. Agents run shell tools with approval and call MCP servers, and the cloud agent has the GitHub and Playwright MCP servers on by default. Tool orchestration serves the coding work and is not the product's center.
Validate
Debugging: Supports
Debugging, supports. Copilot chat and agents use repository context and terminal output to investigate failures. Dedicated debugging and production-diagnosis tools still handle their own work.
Testing: Supports
Testing, supports. The cloud agent runs tests and linters in GitHub Actions before it finishes. Your team still owns the test infrastructure.
Code review: Core
Code review, core. Copilot code review comments on pull requests on GitHub and in IDEs. Admins can enable automatic review for every pull request and extend it to members without Copilot licenses.
Application security: Supports
Application security, supports. Before finishing, the cloud agent checks its changes with CodeQL, secret scanning, and the GitHub Advisory Database, and it can be assigned code scanning alerts. The scanning itself belongs to GitHub's security products.
Ship
Source control: Supports
Source control, supports. Agent work lands on a copilot/ branch with signed commits and a draft pull request that branch protections govern. GitHub itself is the source-control system of record, and Copilot works inside it.
CI/CD: Touches
CI/CD, touches. Both the cloud agent and code review run on GitHub Actions runners, and Copilot CLI can run inside workflows. Builds and deployment stay with the delivery platform.
Operate
Observability: Touches
Observability, touches. Given the relevant context, Copilot can help investigate production issues, but it provides no observability of its own.
Used for feature development, code generation, code review, refactoring, debugging, testing, and engineering automation, by software engineers, engineering teams, and platform teams.

How to read this map. Each layer lists the products that structurally own it, so a product that only touches a layer isn't listed among its owners. GitHub Copilot is underlined in teal where it is Core, and its rows sit a shade lighter; where it supports or touches a layer, that row names it first.
