Our take

The most ubiquitous coding assistant — wins on reach and integration, not raw power.

What it is

GitHub Copilot is the AI pair programmer that put AI coding on the map. It is deeply integrated across GitHub.com, VS Code, JetBrains, Visual Studio, and even the terminal. It started as autocomplete and has grown into chat, multi-file edits, and (in Copilot Workspace) full task agents.

Best for

Inline autocomplete while typing
Chat with your code in the editor
Use Copilot Workspace to plan and execute larger tasks

Pros

Most ubiquitous coding assistant — works everywhere
Tight GitHub integration (PRs, issues, code review)
Good free tier

Cons

Not the best at long-horizon autonomous tasks
Cloud-only — code leaves your machine

Quick start

Free tier: github.com/features/copilot → "Get started" → sign in with your GitHub account → 2,000 code completions / month + chat access.
Pro ($10/mo): install the Copilot extension in VS Code / JetBrains / Visual Studio → sign in → 300 premium requests and unlimited chat.
Use Copilot Chat: Ctrl+I (inline edit), Ctrl+Shift+I (chat panel), or @workspace in chat to ask about your repo.
Open a PR → Copilot auto-generates a description draft; review and commit.
Team / Business ($19–$39 per user/month) adds admin controls, audit logs, and code referencing on private repos.

Sample input / output

Input

In VS Code chat: "Refactor this 200-line React component into 3 smaller components, keep tests green, and write a single-line PR description."

Output

src/ProfilePage.tsx → split into src/ProfileHeader.tsx, ProfileBody.tsx, ProfileFooter.tsx. New index.ts barrel.
12/12 tests still green. Lint clean (no new warnings).
PR opened with auto-generated description:
  "Refactor ProfilePage into Header/Body/Footer components. No behavior change. Tests unchanged."

Should you pick this?

Pick it if You want the most polished and ubiquitous AI coding experience, with first-class GitHub PR / Issue / code-review integration and a generous free tier.

Skip it if You want self-hosting, BYOK models, or deep project-wide context for big refactors — Cline, Continue, or Claude Code will go further. Copilot is also the default, not the leader.
