GitHub Copilot

The product GitHub sells under the Copilot name spans five surfaces: the editor extensions for VS Code, Visual Studio, JetBrains, Eclipse and Xcode, a terminal CLI, a desktop app, github.com and GitHub Mobile, and a cloud agent that works on a repository without a developer present. The marketing page frames it as "Your AI accelerator for every workflow, from the editor to the enterprise".

The capabilities differ by surface. In an editor you get inline suggestions, inline chat and agent mode. On github.com you can assign work to Copilot and it creates a pull request, and the cloud agent can research and plan "with or without a pull request". In the terminal, Copilot CLI makes and commits changes locally or on GitHub and exposes a programmatic mode. Pull request review and the cloud agent are the two features the free plan does not include.

There are four individual tiers and two organization tiers. Free is $0, Pro is $10 a month, Pro+ is $39 and Max is $100; Copilot Business is $19 per granted seat per month and Copilot Enterprise $39.

The plan price is only half the bill. Agent mode, code review, the cloud agent, the CLI and chat all consume GitHub AI Credits, and the plans page states total credit values of $15, $70 and $200 a month against the $10, $39 and $100 prices, split into base credits and a "flex allotment" that GitHub says "may change over time". Pro and above may purchase additional credits; Free may not. Credit consumption varies by model, which means the same plan costs different amounts of capability depending on whether a developer reaches for a Haiku or an Opus class model.

Organization credits behave differently again: GitHub describes included AI credits as shared org-wide with admin controls for spending, and shows pooled usage as not included on any individual plan.

Copilot Free is a standing $0 plan rather than a trial. It carries an allowance of AI credits, restricts model choice to auto model selection only, and caps inline suggestions at 2,000 completions a month. Copilot Chat skills in IDEs are explicitly not available on it.

Two eligibility conditions matter. Free is "only available to individual developers who don't have access to Copilot through an organization or enterprise", and verified students, teachers and maintainers of popular open source projects can get paid-tier access at no cost. A developer whose employer has a Business seat cannot fall back to Free.

Agents reach GitHub through the GitHub MCP Server, which GitHub publishes itself. The remote endpoint is https://api.githubcopilot.com/mcp/ and is hosted by GitHub, with OAuth or a personal access token for authentication, an insiders channel at /mcp/insiders, and a local Docker image at ghcr.io/github/github-mcp-server for hosts that do not support remote servers. GitHub Enterprise Cloud with data residency is supported at a copilot-api.<subdomain>.ghe.com host; GitHub Enterprise Server is not, and the docs state Copilot is not currently available for GitHub Enterprise Server at all.

The server is documented for hosts beyond Copilot, including Claude Desktop and Claude Code, Codex, Cursor, Windsurf and Zed, so the GitHub tools are usable by agents that are not GitHub's. In the other direction, integration with MCP servers is included on every Copilot plan for agent mode, and from Pro upward for the cloud agent.

GitHub also operates the MCP Registry at github.com/mcp, a catalogue of community servers with one-click install, which is a discovery surface rather than part of the Copilot subscription.

Copilot is a client over other companies' models. The plan documentation lists Anthropic Claude, Google Gemini and OpenAI GPT families side by side, with availability differing per tier: Claude Sonnet and Haiku class models are available on Pro, while the Opus class models and several Gemini and GPT variants are marked not included on Pro and included on Pro+ and Max. Free and Student get auto model selection only.

The practical consequence is that a model named on the marketing site is not necessarily a model your plan can select, and the tier-by-tier model table is the only place that settles it. Copilot can also delegate tasks to third-party coding agents including Claude and Codex, which GitHub marks as a preview and as not included on Free or Pro.

Parts of Copilot are published under permissive licenses. The VS Code Copilot Chat extension is MIT licensed, though that repository is archived with development moved into the main VS Code repository, and the GitHub MCP Server is a public Go project with a published Docker image. The hosted Copilot service, the prompts and the model routing are not published, and no license is offered for them.

That matters for anyone evaluating Copilot as infrastructure rather than as a subscription: the client is inspectable and forkable, the thing doing the work is not.

GitHub publishes REST API endpoints for Copilot covering usage metrics, user and seat management, content exclusion rules and cloud agent repository settings. These are management APIs: they let a platform team provision seats, pull adoption metrics and exclude paths from Copilot's context.

For driving the agent itself the path is Copilot CLI, which the plans page lists with a programmatic mode included on every tier, including Free. A team that wants Copilot inside its own build pipeline is scripting the CLI, not calling a completions endpoint.

The fit is strongest where the work already lives in GitHub: issues, pull requests, Actions runs and reviews are the objects Copilot's agents act on, and the MCP server exposes exactly those. App modernization for Java and .NET is included from Pro upward, which points at the same buyer.

It fits less well in three cases. Teams on GitHub Enterprise Server are excluded, since Copilot is not currently available there. Buyers who need a predictable monthly figure face a credit meter with a flex allotment GitHub reserves the right to change. And anyone wanting to call a model directly rather than through an editor, CLI or the cloud agent is looking at the wrong product: the published APIs manage Copilot, they do not serve completions.
