XME.digital Core

Open-source fast-code platform for building SaaS products, B2B/B2C solutions, and rapid prototyping (formerly known as a XM^ONLINE)

About

XME.digital Core is the foundation of the XME.digital platform, available under the Apache-2.0 license. We believe we've built a powerful tool and want to share it with engineers and developers worldwide.

Use XME.digital Core to:

• Build your own SaaS products with complete independence
• Develop B2B and B2C solutions
• Rapidly prototype startup ideas with future scalability in mind

The Core includes all essential developer tools to implement and run your applications. Enterprise features are available separately through XME.digital.

Key Features

• Multi-tenancy — dedicated isolated spaces for each customer with individual configuration, user management, and access rules
• Dynamic Domain Objects — create and configure entities dynamically without hard-coding
• Attribute-Based Access Control (ABAC) — context-aware, risk-intelligent access control with flexible policy rules
• Logic Extension Points (LEP) — extend business logic using Groovy, JavaScript, or TypeScript without full development cycles
• Dashboards & Widgets — configurable visual displays with multiple widget types
• Balance Management — monetary and non-monetary balance operations with policies and thresholds
• Timeline — chronological event tracking and monitoring for any entity
• Anylogin — flexible authentication via username, email, phone, or social networks
