OTOBO
Flexible web-based ticketing system used for customer service, help desk, IT service management.
It is a web‑based, modular platform for managing tickets and service requests across IT, customer support, HR, facilities and other departments. The core provides classic ticket handling, a knowledge base with internal and external access, workflow automation, and optional IT Service Management extensions such as a configuration‑management database for tracking assets like hardware, buildings or vehicles.
The system is designed for organizations that need a self‑hosted, fully open‑source solution without subscription fees. It can be customized through extensions and configuration to fit specific processes, and it supports ITIL‑aligned practices for ITSM, as well as broader enterprise service management and customer service scenarios.
Distributed under GPL‑3.0, the software is stable and maintained by a community‑driven project that encourages contributions via forums and GitHub. Documentation, professional consulting, training and managed hosting options are available from the core developers.
