Frappe HR is a comprehensive open-source HR and payroll software, offering over 13 modules for employee management, leave tracking, expense claims, and performance management. Initially part of ERPNext, it became a standalone product due to its growth and maturity. Built on the Frappe Framework, the software provides robust integration with ERPNext and features like geolocation-based attendance and a mobile app. Users can set it up on Frappe Cloud or locally using Docker and comply with development guidelines for contributing.
