Best AI coding tools

Editors and assistants for changing a real codebase.

Ranked for repository work. Hosted playgrounds are useful and they are not the same purchase as an editor your team lives in.

  1. 1

    Cursor

    Start here for an editor that can change the repo.

  2. 2

    GitHub Copilot

    Start here if the requirement is GitHub.

  3. 3

    Claude

    The assistant to keep beside the editor.

  4. 4

    Windsurf

    The closest alternative AI IDE.

  5. 5

    ChatGPT

    Useful for explanation and snippets, weaker as the daily editor.

Bottom line

Cursor first for an AI-native editor. GitHub Copilot first when the requirement is GitHub. Claude remains the assistant to keep open beside either.
