It has composer support in version 3. According to the documentation you can set in application/config/config.php .
$config['composer_autoload'] = TRUE; //around 134 lineIt will search for composer autoload script inside application/vendor . Place composer.json inside application(Codeigniter's application folder, not the root) folder. Then run composer init, and then - composer install.
And if CI fits you, then its right tool for your job:)
