Understanding the Platform

Visual Builder vs Visual Builder Studio — Two Complementary Tools

Oracle’s Visual Builder platform comprises two products. eAppSys works with both.

Oracle Visual Builder (VB)

  • Managed platform for hosting and running visual applications
  • Includes web/app server, database, REST proxy, and identity service integration
  • Browser-based visual development environment — no software to install
  • Hosts standalone web and mobile applications with their own security and custom domain
  • Hosts standalone web and mobile applications with their own security and custom domain
  • Licensed product — OCPU per hour pricing
  • Deploy mobile, web, and desktop apps anywhere — cloud and on-premises

Oracle Visual Builder Studio (VB Studio)

  • Free with every Oracle Fusion Cloud Application subscription
  • Development platform for teams — Git, CI/CD, issue tracking, agile planning, dashboards
  • The development environment for building Fusion Cloud Application extensions
  • Extensions deployed directly into Fusion instances — integral UI, not iFramed
  • Oracle uses VB Studio internally to build new Fusion Cloud Application modules
  • Includes the development environment — Visual Builder Runtime licence required to host standalone apps
Fusion Cloud Extension Patterns

Three Ways to Extend Oracle Fusion Cloud with Visual Builder Studio

Oracle confirms three extension patterns. eAppSys selects the right pattern based on the use case, Fusion pillar, and business requirement.

1. Oracle Fusion Cloud Extensions

  • Extend existing Redwood pages — add, remove, or modify fields, components, and layouts
  • Create new Application Extension pages within the Fusion UI — integral, not iFramed
  • Extension access controlled using Fusion Apps roles — extension, flow, and page level
  • Single sign-on — same Fusion users, roles, and authorisation as the core application
  • Extensions deployed via VB Studio CI/CD to Fusion development, test, and production instances
  • Covers all Fusion pillars — HCM, ERP (Financials), SCM, CX, and Procurement

2. Standalone Web & Mobile Applications

  • Browser-based visual development — responsive web apps and Progressive Web Apps (PWA)
  • PWA: install-to-home-screen, offline fallback, and native device OS integration
  • Custom domain names, own security implementation, and own database for custom objects
  • Service catalog integration — direct access to Oracle Fusion Cloud business objects via REST
  • Mash-up multiple REST data sources — Fusion, OCI services, and external APIs in one application
  • Customise using standard HTML5, JavaScript, and CSS for full flexibility

3. Visual Builder Studio CI/CD

  • Git repository setup — distinct repositories per Fusion pillar (HCM, SCM, ERP, CX)
  • Build pipelines — automated packaging and deployment of extensions to Fusion instances
  • Workspace management — isolated development environments per developer or feature branch
  • Merge request workflows — code review, approval gates, and conflict resolution
  • Environment mapping — VB Studio environments linked to Fusion development, test, and production
  • Issue tracking, agile planning, and development dashboards — full SDLC toolchain

4. REST Service Integration

  • Oracle Fusion Cloud REST API integration — business objects and events across all Fusion pillars
  • Service catalog — one-click access to Oracle Cloud Application business objects
  • External REST service integration — pick from catalog or invoke any REST endpoint
  • REST proxy — secure authentication and calling of services from within Visual Builder
  • OCI service integration — connect Visual Builder applications to OCI AI, storage, and streaming
  • Custom data objects — replace spreadsheets with multi-user Visual Builder web applications

Fusion Cloud Extension Patterns

Three Ways to Extend Oracle Fusion Cloud with Visual Builder Studio

Oracle confirms three extension patterns. eAppSys selects the right pattern based on the use case, Fusion pillar, and business requirement.

Edit an Existing Redwood Page

Customise existing Oracle Fusion Cloud pages — add or remove fields, change layouts, show or hide components, and add custom validation rules. Uses VB Studio Express Mode. Available across HCM, SCM, ERP, and CX Redwood pages.

Create a New Redwood Application Extension

Build entirely new pages within the Fusion UI framework — using Fusion business objects, custom VOs, or external REST data sources. Extensions appear in Oracle Cloud Application menus and share Fusion authentication and authorisation.

Standalone Visual Builder Application

Build a standalone web or mobile application hosted on the Visual Builder platform — with its own domain, security model, and database for custom objects. Connects to Fusion data via REST service catalog. Accessible from anywhere, not just within Fusion.
Extension Use Cases by Fusion Pillar

What eAppSys Builds in Visual Builder — by Module

eAppSys has delivered Visual Builder extensions across all four Oracle Fusion Cloud pillars — representative use cases for each are listed below.

HCM Extensions

Custom employee self-service pages, talent review workflow extensions, onboarding checklist applications, custom absence reporting dashboards, and performance review process extensions — all within the Fusion HCM Redwood UI.

ERP / Finance Extensions

Custom journal entry workflows, expense approval extensions, supplier payment status portals, budget monitoring dashboards, and invoice processing workflow pages — integrated with Fusion Financials business objects.

SCM Extensions

Supplier onboarding portals, custom procurement approval workflows, inventory adjustment applications, order status dashboards, and Redwood page extensions for Supply Chain Cloud using VB Studio Express Mode.

CX / Sales Extensions

Custom opportunity management pages, account planning applications, deal desk approval workflows, customer 360 dashboards consuming Fusion CX business objects, and sales analytics extensions within the CX Redwood UI.

Common Questions

Frequently Asked Questions

What is Oracle Visual Builder (VBCS)?
Oracle Visual Builder (formerly Visual Builder Cloud Service — VBCS) is Oracle’s managed platform for building and hosting web and mobile applications. Oracle Visual Builder lets you create and deploy web and progressive web applications visually. Rapidly create and deploy engaging web and mobile apps directly from the browser. Visual Builder provides a web/app server, database, REST proxy, and Oracle identity service integration. Extensions built on Visual Builder Studio are an integral part of the Fusion UI — not iFramed — and share Fusion authentication and authorisation.
Oracle Visual Builder (VB) is a service that offers a managed platform to host visual applications. Visual Builder Studio (VB Studio) is a platform for teams to manage their development process and source code, and to automate CI/CD. VB Studio is a free entitlement for any paying Oracle Cloud customer — automatically provisioned for every Oracle Fusion Cloud Application customer. VB Studio includes Git, CI/CD, issue tracking, and the development environment for Fusion extensions. A Visual Builder Runtime licence is required to host standalone applications.
Extend Oracle Cloud Applications — embed your applications as custom tabs within Oracle Cloud Applications, or as menu options that link to external applications. Single sign-on access — leverage the same users and roles as Oracle Cloud Applications in your extensions. Extensions are an integral part of the Fusion UI experience — not iFramed — and appear in Oracle Cloud Application menus. Oracle itself uses VB Studio to build new modules across Oracle Fusion Cloud Applications.
Visual Builder Studio supports extensions across all Oracle Fusion Cloud pillars — HCM, ERP, SCM, and CX. Oracle confirms access control: ‘Define who can access your extension using Fusion Apps roles — available at the extension, flow, and page levels giving you granular control.’ Three patterns are supported: editing an existing Redwood page; creating a new Redwood Application Extension; and developing a standalone Visual Builder application connecting to Fusion REST services.
eAppSys provides Oracle Visual Builder development across four areas: Oracle Fusion Cloud Extensions (editing Redwood pages, creating new Application Extensions, extending HCM, ERP, SCM, and CX using VB Studio); Standalone Visual Builder Applications (web and mobile applications hosted on the Visual Builder platform); Visual Builder Studio CI/CD (Git repository management, build pipelines, and automated deployment to Fusion instances); and REST Service Integration (connecting Visual Builder applications to Fusion Cloud REST APIs, OCI services, and external data sources). Ongoing support is provided through OracleCloudCare.
