GitHub Copilot: what it is, who it is for and alternatives

Category: AI coding tools

GitHub Copilot is GitHub’s AI coding assistant for autocomplete, chat, and agent-style help inside common IDEs and on GitHub.com. Usage on paid plans is often framed in AI credits, with pooled allowances on Business seats and overage rules when the vendor publishes them.

It fits individual developers on Free, Student, Pro, Pro+, or Max-class plans, and organisations on Business or Enterprise that need seat admin and pooled credits. Students and educators should confirm current eligibility on GitHub’s own pages. It is not Microsoft 365 Copilot: that product targets Word, Excel, Teams, and related Microsoft 365 apps under different licensing.

AI Stack Wise lists verified seat and credit-related figures from official GitHub sources and links a calculator for seats and credit overage where the dataset supports it. Unverified annual prices stay labelled.

Typical jobs it handles

Developers rely on Copilot for inline code completion, chat inside the editor about selected code, generating unit tests, explaining errors, and drafting pull request descriptions. Its coding agent can take a GitHub issue, work in a cloud environment, and open a pull request for review. Code review suggestions on pull requests and command-line help round out the surface.

Who should look elsewhere

Buyers who want help with Word, Excel, Outlook or Teams are looking for Microsoft 365 Copilot, a different product with separate licensing. The consumer Microsoft Copilot app is also different again. Developers who want a fully AI-centred editor may compare Cursor or Windsurf, and terminal-first users may compare Claude Code or OpenAI Codex.

How it differs from close peers

Copilot’s main strength is reach: it plugs into VS Code, Visual Studio, JetBrains IDEs, Xcode, Neovim and github.com, and it ties into GitHub organisation policy, audit and seat management. Cursor, by contrast, asks you to adopt its editor. Within the Copilot family, keep three names apart: GitHub Copilot for code, Microsoft 365 Copilot for office work, and Microsoft Copilot for consumer chat.

Plan posture

GitHub offers a free tier with monthly caps, individual Pro and higher Pro+ options, and Business and Enterprise seats managed by organisations. Premium requests for advanced models are metered against allowances, and verified students, teachers and maintainers of popular open-source projects may qualify for complimentary access under GitHub’s rules.
