Our take
Pick Aider if developers who already live in git and a TTY and will paste an API key. Pick Devin if engineers who will let an agent open PRs and will watch the quota. Skip Aider if people who want an IDE Agent sidebar (Cursor, Cline, Continue) and will not run aider in a repo. Skip Devin if people who want an IDE with Tab (Cursor, GitHub Copilot) and will not run Devin sessions.
