Our take
Pick Aider if you're a developer who already live in git and a TTY and will paste an API key. Pick GitHub Copilot if you're a developer already in GitHub who want completions and chat without switching to a separate AI IDE. Skip Aider if you're people who want an IDE Agent sidebar (Cursor, Cline, Continue) and will not run aider in a repo. Skip GitHub Copilot if you're on a team that cannot send code to GitHub’s
