Docker4Drupal vs Kool

Docker4Drupal is a local Drupal environment built from Docker images and a preconfigured Compose setup. It lists images for Drupal CMS 2 and vanilla Drupal 11 and 10, with a stack that includes Nginx, Apache, PHP, MariaDB, PostgreSQL, Valkey, Redis, Memcached, Varnish, Node.js, Solr and OpenSearch. Optional tools include Mailpit, Gotenberg, Webgrind, Xhprof viewer, Adminer, phpMyAdmin, Selenium Chrome and Traefik. You can use the bundled Drupal setup or mount an existing codebase. Traefik supports routing multiple projects through a shared port or separate ports; Mailpit catches outbound email by default, and OpenSMTPD can be enabled for delivery. Documentation covers Xdebug for web and command-line debugging and IDE configuration such as PHPStorm. Docker is required, with Docker Compose also required on Linux. Database volumes persist by default, with bind mounts recommended when data should stay attached across restarts. It is free at free under the MIT license, for local development; the project directs server deployment users to Wodby’s Drupal stack.

Kool.dev Cloud is a platform-as-a-service for deploying containerized web applications, either on managed hosting or infrastructure a team provides. Deployments can start with a Git push, trigger automatic builds, create preview environments for pull requests, and avoid downtime. Kool supports Docker Compose compatibility and existing Compose setups. For bring-your-own-cloud deployments, it installs Kubernetes using k0s on a VPS with SSH access; named providers include DigitalOcean, Hetzner, AWS, Vultr, OVH, and Linode, and Kool says any VPS with SSH can be used. Managed database options include MySQL, PostgreSQL, Redis, MongoDB, and Elasticsearch. Monitoring includes Prometheus and one-click Grafana dashboards. Listed security features include automated hardening, network isolation, secrets management, SSH key authentication, cluster activity logs, and credentials encrypted at rest. Plans include BYOC Free, managed cloud plans from $5.00 per month, and BYOC Pro at $49.00 per month. The BYOC Free tier is limited to one cluster, one node, one environment, and one app; a valid credit card is required after seven days. Kool lists documentation, community Discord, and email support for all plans, with priority support for Pro and Team.
