Verdict
Pick Copilot if you want an assistant inside the editor you already use, especially Visual Studio, Xcode, Eclipse or Neovim, which Claude Code doesn’t support. It’s cheaper to start, with a free plan and a $10 Pro plan, and it lets you switch between Claude, GPT, Gemini and other models in one place. Its cloud agent and code review are built into GitHub, so issues and pull requests are where the work happens.
Pick Claude Code if you want a strong agent that works across your whole codebase and you’re happy with Claude models. It comes with every paid Claude plan, so if you already pay for Claude, your coding is included. Hooks, subagents, skills and scheduled cloud tasks make it well suited to long, multi-step work.
On cost, Copilot’s credits are easy to predict but can run down quickly on premium models, since every request is billed against your allowance. Claude Code’s allowance is shared with your Claude chats and has a five-hour window on every plan except Ultra.
On privacy, note that Copilot’s individual plans now train on your interactions by default. Opt out in your GitHub Copilot settings if that matters to you. Claude’s consumer plans train only if you allow it.
You don’t have to choose: Copilot Pro and above can run Claude Code as a third-party agent.
Frequently asked questions
Is Copilot or Claude Code cheaper?
Copilot is cheaper to start: Pro is $10 a month and there's a free plan. Claude Code needs at least Claude Pro at $20 a month. For heavy agent work, compare Copilot's credit allowance (20,000 credits, worth $200, on the $100 Max plan) with Claude Max at $100 for 5x Pro usage.
Can I use Claude Code inside Copilot?
Yes. GitHub lists Claude Code and Codex as third-party agents available in Copilot from the Pro plan upwards.
Which is better for JetBrains or Visual Studio users?
Both support JetBrains IDEs. Only Copilot supports Visual Studio, Eclipse, Xcode and Neovim.
Does either train on my code?
Copilot Free, Pro and Pro+ use interaction data for training by default unless you opt out; Business and Enterprise don't. Claude Code trains on consumer sessions only if you allow it, and not on Team, Enterprise or API data.
