Our take
Pick Aider if developers who already live in git and a TTY and will paste an API key. Pick OpenCode if developers who want a local MIT agent and will connect a provider or use the included free models. Skip Aider if people who want an IDE Agent sidebar (Cursor, Cline, Continue) and will not run aider in a repo.
