Frappe HR is a complete, open-source Human Resource Management System (HRMS) designed for organizations seeking full control over their HR and payroll operations without vendor lock-in. Built for teams of all sizes, it replaces fragmented SaaS tools with a unified platform that handles everything from recruitment and onboarding to exit interviews and payroll processing. It is specifically tailored for technical teams and businesses that value transparency, customization, and integration with existing financial systems.
Built on the Frappe Framework (Python + JavaScript) and Frappe UI (Vue-based), Frappe HR offers a low-code environment for custom workflows, a mobile PWA for on-the-go access, and seamless integration with ERPNext for accounting. It supports deployment via Docker or local bench setups and is hosted on Frappe Cloud for managed infrastructure, making it suitable for both self-hosted and cloud-based deployments.
What You Get
- Employee Lifecycle Management - End-to-end tracking from recruitment and onboarding to promotions, transfers, and exit interviews with automated documentation and feedback collection.
- Leave and Attendance with Geolocation - Configure regional holiday calendars, track check-ins/out via mobile geolocation, and monitor attendance with real-time reports and balance calculations.
- Payroll & Taxation Engine - Create salary structures, define income tax slabs by region, process standard and off-cycle payments, and generate detailed income breakup reports for compliance.
- Performance Management with KRAs - Set and track employee goals aligned with key result areas, enable self-evaluations, and streamline appraisal cycles with customizable review forms.
- Expense Claims & Advances with Workflows - Submit and approve expense claims and advances with multi-level approval chains, integrated directly with ERPNext accounting ledgers.
- Frappe HR Mobile App (PWA) - Apply for leaves, check in/out using geolocation, view pay slips, and access employee profiles from iOS and Android devices without installing a native app.
- Low-Code Customization - Build custom forms, reports, print formats, and approval workflows without writing code using Frappe Framework’s doctype and desk builder tools.
- ERPNext Accounting Integration - Automatically sync payroll, expenses, and advances with ERPNext’s accounting module to eliminate reconciliation work between HR and finance systems.
Common Use Cases
- Running a multi-location payroll for 500+ employees - A manufacturing company uses Frappe HR to manage shift-based attendance, geolocation check-ins, and regional tax slabs across 12 branches with integrated ERPNext accounting.
- Managing remote teams with mobile-first HR - A SaaS startup with distributed engineers uses the Frappe HR PWA to handle leave requests, expense claims, and performance reviews from mobile devices without requiring desktop access.
- Customizing HR workflows for compliance - A healthcare provider configures custom approval chains for overtime claims and creates print formats for labor law-compliant payslips using Frappe’s low-code tools.
- Replacing expensive SaaS HR tools - A nonprofit organization replaces Workday and BambooHR with Frappe HR to eliminate per-employee licensing fees and gain full ownership of their HR data.
Under The Hood
Architecture
- Modular monorepo structure isolating frontend, HR modules, and payroll components into distinct workspaces with clear ownership boundaries
- Business entities modeled as DOCTYPEs with built-in validation and workflow hooks, enabling declarative business logic without custom controllers
- Event-driven communication between modules via doctype lifecycle events, ensuring loose coupling and cross-functional consistency
- Dependency injection through Frappe’s service registry, allowing services like notifications and file handling to be decoupled from core controllers
- CI/CD pipeline enforces architectural integrity across branches with automated merges, backports, and quality gates
Tech Stack
- Python 3.10+ backend powered by Frappe Framework with ERPNext integration, using Ruff for consistent code formatting and linting
- Vue.js and Next.js frontends built with Vite, leveraging Frappe-UI components and client-side rendering tools for dynamic HR interfaces
- Yarn workspaces manage multi-repo dependencies with dedicated build scripts for PWA and roster modules
- Pre-commit hooks enforce code quality across Python and JavaScript files using Ruff, Prettier, and standard linters
- Translation workflow integrated via Crowdin with automated .pot/.po synchronization and PR labeling for localization
Code Quality
- Extensive test suite unified under a shared base class, standardizing setup and assertions across HR modules
- Custom validation exceptions enforce business rules with clear, behavior-driven test cases covering edge conditions
- Integration tests simulate real-world workflows by combining multiple doctypes to validate cross-module interactions
- Inconsistent test coverage across modules, with some areas lacking comprehensive test implementations
- Naming conventions align with framework standards, producing highly readable and intent-revealing test methods
- Limited type annotations due to reliance on Frappe’s dynamic ORM, trading compile-time safety for development flexibility
What Makes It Unique
- Native attendance and holiday tracking with reactive calendar rendering, eliminating external library dependencies
- Unified resource abstraction layer that auto-synchronizes employee data between UI and server, reducing boilerplate
- Context-aware components that dynamically adapt to user roles using dependency injection, not conditional code paths
- Declarative list views generated from doctype metadata, enabling configuration-driven HR workflows
- SVG-based branding with semantic color coding that enhances accessibility while preserving brand identity across modules
