Akuity Platform vs Deployer

Akuity Platform has no write-up on Specifiction yet; its figures are above.

Deployer is a PHP deployment tool for sending applications to servers. It switches releases through atomic symlinks, so a deployment does not expose an incomplete state, and a failed release can be reverted with one command. The command line can list releases and return to the latest good release. Tasks run concurrently across selected hosts by default, with an option to limit concurrency. Projects describe hosts and tasks in deploy.php or deploy.yaml files and may add custom build tasks. Recipes cover Laravel, Symfony, WordPress, Drupal, Magento, CakePHP, CodeIgniter, Yii, Contao, Shopware, TYPO3, and Sulu. Deployer connects over SSH, can open an interactive SSH session, and includes a recipe for provisioning Ubuntu with firewall, PHP, database, and HTTPS configuration. Installation is available through Composer, Phive, a PHAR bundle, or Docker. CI/CD guidance covers GitHub Actions, GitLab CI/CD, and Bitbucket Pipelines. It is free and open source, with Linux, macOS, API, and self-hosted options.
