FAQ
They serve different workflows. Copilot excels at real-time in-IDE suggestions; Claude Code is better for agentic, multi-step terminal tasks across a codebase. Many developers use both.
GitHub Copilot is easier to start — it installs as an IDE extension and works immediately. Claude Code requires more setup and works best when you can review and steer agent changes.
