Deployer

Deployer is a free, open-source PHP deployment tool for teams that run their own servers and want deployment logic kept with the application. It is strongest for PHP projects using SSH-accessible hosts, while teams wanting a hosted runtime or broad, non-Ubuntu provisioning should look elsewhere.

Overview

Deployer runs project-defined tasks against remote servers, localhost, Amazon EC2 instances and Ubuntu VPSs rather than supplying an application platform. That division of responsibility suits developers who already control their infrastructure: they keep ownership of the hosts and release process, but remain responsible for server operations.

Each project describes hosts and tasks in a deploy.php or deploy.yaml recipe. Custom build tasks let a team adapt the workflow to its application instead of accepting a fixed pipeline. Project installation is particularly sensible for CI/CD because the project can pin its Deployer version.

Key features

Release publication uses atomic symlink switching, so visitors should not encounter a partially updated application while a deployment is in progress. The CLI can list releases and return to the most recent good release before the current one in a single rollback command. That is a practical recovery mechanism for server-based PHP delivery, although operators still need to investigate the change that caused the failure.

Tasks run in parallel across selected hosts by default. A concurrency limit is available when a fleet, database, or dependent service needs a slower rollout. This combination favors teams deploying to several machines, while smaller installations can leave the default behavior unchanged.

SSH is both the transport and the route to an interactive session opened with the configured host. The host guide recommends placing sensitive SSH parameters in ~/.ssh/config rather than in the project recipe, keeping credentials and connection details out of shared deployment code.

The recipe catalogue includes Laravel, Symfony, WordPress, Drupal, Magento, CakePHP, CodeIgniter, Yii, Contao, Shopware, TYPO3 and Sulu. Framework-oriented starting points reduce initial scripting for PHP teams, while the recipe model leaves room for application-specific tasks.

Installation can be global or project-local through Composer, via Phive, or through a PHAR bundle that does not require Composer; the download options also include Docker. CI/CD guidance covers GitHub Actions, GitLab CI/CD and Bitbucket Pipelines, so an existing pipeline can invoke the same command-line workflow.

The provision recipe can configure an Ubuntu server's firewall, PHP, database and HTTPS. It requires root SSH key authentication and targets Ubuntu, making it useful for a new Ubuntu VPS but a poor fit for teams standardizing on another operating system or avoiding root-based provisioning.

Pricing

Free and open source — free. Deployer is MIT licensed, with no paid plan, trial, seat charge, quota or usage limit stated. The free model is well suited to individual developers and teams that can operate their own hosts without a vendor subscription. It does not include a hosted service, so infrastructure and its operating costs remain yours.

Platforms

Deployer supports API, Linux, macOS and self-hosted use. Its deployment targets include remote servers, localhost, Amazon EC2 instances and Ubuntu VPSs. The command-line, SSH-oriented approach fits Unix-based development and server environments; teams seeking a browser-first managed platform should consider an alternative.

Who it's for

Choose Deployer if you build PHP applications, have SSH access to the machines that run them, and want recipes, parallel execution, atomic releases and a direct rollback command. It is also a good match for CI/CD teams that need a project-pinned deployment tool and for operators provisioning an Ubuntu VPS with the supplied recipe.

Look elsewhere if you want the vendor to host the runtime, need Kubernetes-native delivery, or require provisioning beyond Ubuntu. Deployer gives control, but that control comes with responsibility for the servers, SSH configuration and deployment code.

Pros and cons

Pros

• Atomic releases and rollback: symlink switching avoids an exposed partial release, and one command restores the previous good version.
• PHP-focused recipes: coverage for major frameworks and platforms shortens the path to a workable project recipe.
• Flexible execution: parallel host tasks, configurable concurrency and custom build tasks accommodate both small and multi-host deployments.
• Open distribution: Composer, Phive, PHAR and Docker installation options, plus MIT licensing, avoid a subscription dependency.

Cons

• Self-managed infrastructure: Deployer executes against your hosts and does not provide a managed application runtime.
• Ubuntu-bound provisioning: the provision recipe requires Ubuntu and root SSH key authentication.
• SSH responsibility: teams must manage access and keep sensitive settings in their SSH configuration.
• PHP scope: its framework recipes and deployment model are specialized rather than general-purpose application delivery.

Alternatives

Railway is the better choice when you want a hosted, multi-platform application service and a trial with $5 of credit, two replicas and defined resource allowances.

fastlane suits teams seeking a free MIT-licensed automation tool spanning Android, iOS, Linux, macOS and Windows rather than PHP server deployment.

Northflank is preferable for a managed platform with a free Sandbox offering two services, one database and two cron jobs.

Upsun (formerly Platform.sh) fits teams wanting a hosted platform with a 15-day trial and monthly credit for one project and one user.

Argo CD is the relevant alternative for declarative, self-managed GitOps delivery on Kubernetes.

AWS CodeDeploy suits AWS-oriented deployments where EC2 updates carry no additional CodeDeploy charge, while on-premises updates cost $0.02 per instance.

Flux CD is another free, open-source Kubernetes delivery project, provided you already operate a Kubernetes cluster.

Octopus Deploy is worth considering when you need a commercial deployment product with machine and tenant add-ons.

Verdict

Deployer is a strong recommendation for PHP developers and small infrastructure teams that want recipe-driven SSH deployments, zero-downtime release switching and fast rollback without a license fee. Choose another product when you need a hosted runtime, Kubernetes-first delivery or provisioning that is not tied to Ubuntu and root SSH access.
