About Oracle APEX

Oracle APEX is a low-code development platform that is trusted worldwide to deliver mission-critical, data-driven applications that are secure, scalable, and built on the Oracle Database.

About Oracle APEX

Oracle APEX is a low-code application development platform that enables rapid delivery of enterprise applications through a declarative development model that is easier to understand, maintain, and extend. Its metadata-driven architecture also makes applications well-suited for AI-assisted development workflows.

Built natively on Oracle Database, Oracle APEX inherits enterprise-grade security, scalability, governance, and data management capabilities. Developers can build and deploy applications with confidence, knowing that data access, user management, and application behavior are governed within a secure, centralized environment—an increasingly critical requirement in the era of AI.

Oracle APEX provides a browser-based development environment for data loading, database object management, REST API development, and application creation. Applications are responsive by default and deliver consistent user experiences across desktop and mobile devices. APEX supports a broad range of use cases, from spreadsheet-based solutions and operational dashboards to productivity applications and mission-critical data management systems.

Oracle APEX is SQL-native. Any logic expressible in SQL can be directly incorporated into an application. The platform combines the power of SQL with low-code development capabilities, offering prebuilt components for data management, analytics, and visualization. Intelligent wizards and declarative tools minimize manual coding while accelerating application delivery.

Oracle APEX provides a fully managed, secure environment for both development and deployment, with no limits on the number of developers or application users. Infrastructure operations—including configuration, patching, monitoring, and upgrades—are managed by Oracle, allowing teams to focus on delivering business value rather than maintaining the platform.

By combining low-code productivity with enterprise-grade capabilities, Oracle APEX enables organizations to deliver solutions faster, reduce development costs, improve consistency, and adapt quickly to changing business requirements. The platform empowers professional developers, citizen developers, and business users to collaborate in building modern, data-centric applications.

APEXlang and Generative Development

APEX apps can optionally use the new APEXlang syntax. APEXlang is an open application specification language for generative development of Oracle APEX applications. It gives developers and LLMs a supported way to represent APEX applications as human-readable files that can be reviewed, versioned, diffed, scanned, validated, and governed.

To learn more, see Open Specification Application Language (APEXlang) and Creating an Application with APEXlang in Oracle APEX App Builder User’s Guide.

About Oracle APEX Cloud Deployment Options

Rapidly build and deploy scalable and secure applications in the cloud with the world's most popular low-code application platform.

Note:

APEX may reside in a local self-managed Oracle AI Database or in a hosted environment (such as an Oracle Cloud service). The sign in process differs depending on where APEX resides. See Oracle APEX in Oracle Cloud.

Oracle APEX AI Application Generator (APEX Service)

APEX Service is a low-code application development platform that enables developers to quickly build feature-rich, mission-critical apps that are easy to maintain. APEX uses AI to both accelerate app development and provide a richer experience to app users. Only pay for the resources consumed when an app is used.

Key features include:

• Includes a specialized Oracle Autonomous AI Database
• Available Always Free shapes and shapes for developers

Oracle APEX AI Application Generator in Oracle Autonomous AI Database

Oracle APEX AI Application Generator in Oracle Autonomous AI Database is installed, enabled, and ready to use in Oracle Autonomous AI Transaction Processing and Oracle Autonomous AI Lakehouse.

Key features include:

• Includes APEX pre-configured and fully managed
• Supports a broad ecosystem of Oracle Database clients
• Available Always Free shapes and shapes for developers

Oracle Database Cloud Services

About Oracle Cloud Infrastructure

Oracle Cloud Infrastructure (OCI) is a set of complementary cloud services that enable you to build and run a wide range of applications and services in a highly available hosted environment.

Oracle Cloud Infrastructure offers high-performance compute capabilities (such as physical hardware instances) and storage capacity in a flexible overlay virtual network that is securely accessible from your on-premises network.

Use Oracle Infrastructure as a Service (IaaS) offerings to quickly set up the virtual machines, storage, and networking capabilities you need to run just about any kind of workload. Your infrastructure is managed, hosted, and supported by Oracle.

Use Oracle Platform as a Service (PaaS) offerings to provision ready-to-use environments for your enterprise IT and development teams, so they can build and deploy applications based on proven Oracle databases and application servers.

Oracle APEX Web Browser Requirements

Oracle APEX requires a JavaScript-enabled browser and supports the current and prior major releases of Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge.

About Oracle REST Data Services

Oracle REST Data Services (ORDS) functions as a communications broker between the Web browser and the Oracle APEX objects in the Oracle database by mapping browser requests into database stored procedure calls.

Oracle REST Data Services is preconfigured and available for all APEX instances. With the default ORDS, Oracle performs any required configuration, patching, and maintenance.

Oracle REST Data Services also enables access to APEX application data using custom REST APIs. Developers can then utilize these APIs from any language environment without installing and maintaining client drivers in the same way they access other external services using the most widely adopted API technology: REST.

Note:

APEX Service supports the creation of custom REST APIs. Direct access of the REST-SQL interface is prohibited.
