Dokku vs Oracle Visual Builder

Dokku is a self-hosted Platform as a Service for building and running applications from Git pushes on a server you choose. It can deploy applications with Heroku buildpacks, Dockerfiles, or Docker images, targeting a single server, Docker containers, or a K3s cluster. Dokku routes web processes, manages background processes and automated cron tasks, and supports deployment rollback and audit logs. Its plugin architecture allows users to add functionality, with official plugins for PostgreSQL, MySQL, Redis, MongoDB, Elasticsearch, and Let’s Encrypt. Per-application SSL/TLS certificate management is supported, and HTTPS responses have HSTS enabled by default. Dokku recommends SSH key authorization for pushes. The free open-source plan costs nothing. Dokku Pro costs $849, paid once and adds a web interface, JSON API, HTTP(S) app push, management tools, scaling, logs, team management, and email support.

Oracle Visual Builder is a browser-based development service for creating and deploying web and progressive web applications. Its visual builder provides drag-and-drop components, actions, and WYSIWYG interfaces, while developers can customize applications with HTML5, JavaScript, and CSS. Apps can use custom data objects and connect to catalogued or external REST services. Teams can access business objects from Oracle Cloud Applications and extend those applications with custom tabs or menu options. Extensions can use the same users and roles as Oracle Cloud Applications without a separate login. Visual Builder is described as a managed development and hosting service with a web server and embedded database for application data. Published apps run in the cloud and can be accessed from desktop or mobile devices. Administrators can require authentication, and developers can configure role-based access and business object permissions, including row-level conditions for viewing, updating, and deleting data. Communication with underlying JET components is secured over HTTPS and REST. Oracle positions the product for teams extending Oracle Cloud Applications and building web or mobile apps with minimal coding. A 30-day trial is offered; no free plan is listed.
