A self-hosted low-code platform for building and hosting multi-user business applications with full data ownership.

REI3 is a self-hosted low-code platform designed for the creation and hosting of multi-user business applications. It provides a framework that enables the development of internal tools and business management systems while ensuring that the organization maintains full ownership and control of its underlying data.
The software operates as a web application and server, allowing administrators to build custom business solutions through a low-code interface. It is intended for deployment on private infrastructure, where it serves as a centralized hub for managing internal workflows, organizational data, and operational processes across different user roles.
Developed using the Go programming language, the platform utilizes a server-side architecture designed for efficiency and stability. It targets organizations that require specialized internal solutions for budgeting, money management, and general business operations. By providing a structured environment, the software allows users to define specific data models and operational flows that align with their unique organizational requirements. This architecture supports the creation of complex ERP systems that can be scaled according to the needs of the business.
The system is designed for users who prefer to avoid external cloud dependencies and require a private environment for sensitive business data. It integrates low-code development principles to reduce the amount of manual coding required to deploy functional business applications. This makes it suitable for technical administrators who need to rapidly iterate on internal tools or for organizations seeking a unified platform for various business management tasks.
