Visual, extensible workflow automation platform for enterprises
Loonflow 3.0 delivers drag‑and‑drop process and form designers, plugin architecture, fine‑grained permissions, and multi‑tenant support, enabling rapid digital transformation for IT, HR, finance, and customer service teams.
Loonflow 3.0 is a self‑hosted workflow engine aimed at enterprises and development teams that need visual process modeling and deep customization. It provides a drag‑and‑drop process designer with conditional branches, parallel tasks, and hook nodes, as well as a visual form builder supporting a wide range of field types. The platform’s plugin architecture and comprehensive RESTful API let you embed custom business logic, integrate with CMDB, monitoring, CI/CD, and other systems, while fine‑grained permission controls and audit logs satisfy compliance requirements. Optional multi‑tenant isolation makes it suitable for SaaS providers or large organizations.
Installation is streamlined through Docker‑compose. After downloading the docker-compose.yml and .env files, adjust the password settings, run docker-compose up -d, and create an admin user with Django’s createsuperuser command. The system is then reachable via a web browser, ready for immediate configuration of tickets, forms, and plugins.
IT Incident Management
Automates ticket routing, escalation, and resolution tracking, reducing mean time to repair.
HR Leave Approval
Provides a visual leave request form and multi‑level approval workflow, ensuring policy compliance.
Financial Reimbursement
Captures expense data, validates policies, and routes approvals, streamlining finance processing.
Customer Service Request Handling
Integrates with CRM via API, auto‑assigns agents, and logs interactions for audit.
Loonflow is built on Django and uses Docker‑compose for containerized deployment.
Through the plugin architecture and RESTful APIs, you can add custom actions, notifications, or integrate external systems.
Multi‑tenant isolation is optional and requires additional authorization configuration.
Download the provided docker‑compose.yml and .env files, adjust credentials, then run `docker-compose up -d` and create a superuser.
The project includes a documentation section with installation guides, API reference, and tutorials; a full ReadTheDocs site is planned for future releases.
