Horilla is an open-source HR management system (HRMS) built on Django. It covers attendance, leave, payroll calculation, recruitment and onboarding, and includes regional modules for payroll in India (PF, ESI, TDS) and the United Arab Emirates (WPS, EOSB). Organisations can run it on their own servers with Docker and the full source code, or subscribe to Horilla Cloud, a managed service run by the vendor. The vendor positions it as an alternative to proprietary cloud HR suites such as BambooHR.
Horilla is developed by Cybrosys Technologies Pvt. Ltd., founded in 2013 with offices in Calicut and Kochi in the Indian state of Kerala, so the vendor is based in India. The LICENSE file of the source repository names the LGPL-2.1 licence. Self-hosting keeps employee data on infrastructure the organisation controls. Horilla Cloud is governed by Indian law. Cybrosys describes itself in its terms as a data processor acting on the customer's instructions, but the terms do not state where Cloud data is hosted.
