Next, to finalize my long list, I used the evaluation criteria below to further compare each of the long list nominees against each other. I also drew on my years of experience in HR to pick which solutions were most likely to provide the most value.

To satisfy your curiosity even further, here are the specific selection criteria I used to create this list:

What is Open-Source HR software?

Open source HR software is a type of human resources management tool with its source code available for anyone to use, modify, and distribute. It allows businesses to customize their HR processes, including employee data management, payroll, recruitment, and performance evaluation, according to their specific needs. This software typically offers cost advantages and flexibility, supported by a community of developers and users.

Features of Open Source HR Software

When assessing which open-source HR software tools to add to my list, I dove into the following features to see how each system fared:

  • Payroll & benefits: Managing calculations for regular pay, overtime, taxes, insurance, and related factors.
  • Employee development & performance: Keeping track of progress and achievements to help plan career growth trajectories. Facilitate learning and professional development.
  • Managing employee information: Keeping track of employee information relating to contact details, positions, rates, vacations, and benefits. Document management is also an asset.
  • Applicant tracking system: Storing information about applicants for specific positions, results of interviews, salary expectations, job offers, etc.
  • Salary & benefits administration: Managing employee salaries and ensuring they receive benefits they are entitled to.
  • Absence management: Dealing with matters and calculations related to vacations, business trips, absenteeism, and sick leave. 

When using open source HR software, you have the freedom to customize the code. However, if customization isn't your priority, explore these HR software platforms that offer out-of-the-box functionalities.

Benefits of Open Source HR Software

Open-source HR software offers numerous benefits for users and organizations. Here are several reasons why you might want to implement open-source HR software in your organization:

  • Cost-Effective: The most common benefit of using open-source software is that it's free. By eliminating the high licensing fees associated with proprietary systems, an open-source system reduces overall operational costs for your business.
  • Customization: Organizations can modify open-source HR software to meet their specific needs, ensuring a tailored solution that aligns with their unique processes and requirements.
  • Community Support: Open-source systems typically come with a vibrant community of developers and users that offer extensive support and resources, providing troubleshooting assistance and regular updates.
  • Transparency: The open nature of the software allows users to see and understand the source code, ensuring there are no hidden functionalities or security concerns.
  • Innovation: Access to the source code encourages innovation, enabling organizations to implement the latest features and improvements quickly.

By choosing open-source HR software, businesses can save on costs and gain the flexibility and control needed to create a system that perfectly suits their needs. These benefits collectively contribute to a more efficient, secure, and adaptable HR management process, positioning organizations for sustained success.

Costs & Pricing for Open Source HR Software

Sometimes it all comes down to price, and open source software is generally very affordable. In fact, in most cases, the software is available to use for free.

Many open-source providers also offer users the option to scale up to a paid version of the same software if you want to access more advanced features. Having that kind of flexibility is great as a user. It means you can download it and spend some time getting comfortable with it before making your decision.

And if you really love it, and want to access more features, you can either scale up, or ask your IT department to try and customize it for your own unique business needs.

Frequently Asked Questions

Here are some answers to frequently asked questions I often hear about open-source HR software:

What does "open source" mean in relation to software?

The term open source refers to a type of software development and distribution model where the source code of a computer program is made available to the public. With that information publicly accessible, other software developers can modify the underlying source code to customize the application for their own specific needs. Open source software is typically developed collaboratively within technical communities of developers who work on the project pro bono (i.e., for free) in order to advance the project along for the greater good of the industry and end users.

What is the difference between HRIS and HRMS?

Human Resources Information Systems (HRIS) are software that offer more basic functions like attendance, time tracking, and payroll processing. Human Resources Management Systems (HRMS) are employee management tools that take functionality a step further by including features like reporting, employee engagement, and performance appraisal.

What software integrations are important for open-source HR software?

Software integrations can save you a lot of grunt work, such as needing to transfer data manually, or via imports and exports, from one system to another. Instead, using native software integration, you’ll be able to improve your team’s productivity and help your HR professionals work more efficiently.

The specific integrations to look for will depend on the type of HR software you’re after, however, integrations with email providers, digital calendars, payroll software, and work platforms like Google Workspace and Microsoft SharePoint are always welcome.
