About Rebuild

REBUILD is an enterprise business platform that focuses on implementing business requirements rather than offering a generic technical framework. Its documentation and interface are in Chinese, and it lets organizations design entities, fields, layouts and forms graphically to assemble systems such as CRM, warehouse management, production reporting, HR and more.

Main capabilities include zero-code modeling, workflow automation with triggers, approval flows and scheduled tasks, fine-grained permissions by team, role and department, web and mobile access with embedding in enterprise messaging apps, and an OpenAPI for integrations and Java or Spring Boot extension. Recent versions add an AI assistant that can operate on business data through natural language, with support for skills, tools, a knowledge base and MCP.

REBUILD is written in Java and licensed under GPL-3.0, with installation by Docker, a standalone package or a Spring Boot jar, and MySQL recommended for production. According to the project, the open-source version is free for internal commercial use by enterprises, while a commercial edition provides more advanced features. It suits small and mid-sized companies that lack development resources.
