The SFTP browser Apple forgot to ship. Transfer browses a server the way Finder browses your disk: press Space to preview a file, open an editable file and every save uploads, and drag, copy and paste between servers and the Finder. It uses the ssh already on your Mac, so your ~/.ssh/config, agent and ProxyJump just work.
Free and open source, for macOS 27 or later on Apple silicon.
