Unlike `package.el`, which relies on downloading pre-built packages from ELPA archives, `straight.el` clones packages directly from their source repositories (typically Git), enabling reproducible and fully source-controlled package configurations.

Unlike traditional Emacs package managers, Elpaca installs packages asynchronously, allowing Emacs to remain responsive during installation and updates.
