Selection Criteria for Open Source Employee Scheduling Software

Wondering how I created this list of the best open-source employee scheduling software? I started out by creating a long list of popular employee scheduling systems based on recent market data. I then examined each system in detail to determine whether their software offered any open-source functionality (i.e., the ability to revise their source code as needed).

To bring you into my process even more, here’s a quick summary of the evaluation criteria I used to create this list. When assessing each system, I asked myself the following questions to see how each system compared to the rest: 

  • User Interface (UI): Is it clean and attractive? (Often a weak point with open source software.)
  • Usability: Are the features easy to learn and master? What tutorials and training are available (if any)? 
  • Software Integrations: Is it easy to connect with other tools? Are there pre-built integrations?
  • Paid Extras: While open source software is free, there may be options to purchase additional features from various vendors. What upgrades are available?

Key Features

In addition to the criteria above, I also assessed the following key features to make my final selections for this list:

  • Employee Management: houses information about all your employees, company structure, and locations.
  • Schedule Management: automates the process of schedule creation according to availability and other criteria.
  • Shift Management: makes it easy for employees to swap shifts and make other shift scheduling changes.
  • Time Management: protective measures to ensure employees are recording their time and time-off accurately
  • Absence Management: allows for proactive management of any gaps that occur in the schedule due to absence.
  • Tracking Payroll Expenses and Budget: integrations with other financial software to provide a big-picture view
  • Employee Self-Service: allows employees to update their own schedules if necessary
  • Reporting and Business Intelligence: provides detailed reporting and analysis for senior management

People Also Ask

If you still have questions about open-source employee scheduling software and what it has to offer, these answers to frequently asked questions are a great place to start:

Is open-source employee scheduling software as good as proprietary alternatives?

Open source tools have real value, and many organizations rely on them to organize employee schedules. But it’s true that, to some extent, you get what you pay for. The main reason to use an open-source alternative instead of a paid option is because you truly need the ability to customize the software for your specific needs. If all you need are run-of-the-mill features, I’d recommend saving yourself the headache and investing in a paid version instead. That way, you’ll have access to customer support whenever you need it too.

Is open-source employee scheduling software reliable?

The tools I’ve included in this list have stood the test of time and are generally reliable. When issues do arise, they are likely to be resolved quickly if you’re willing to dig around for the answer. The open source community is mutually supportive, and you can often get help from developers and other users when you encounter problems. But don’t expect the dedicated customer support you’re entitled to when purchasing a paid software alternative. With open source, you’re often your own customer support, so make sure you’re up for the challenge before you venture down this road.

Can open-source employee scheduling software compete with paid tools?

Free is always an attractive price point, so open source solutions will always appeal to those with tight budgets, or organizations that have the in-house technical capabilities to customize the software for their specific needs. However, when venturing down the open source road, keep in mind that you may be able to get the same functionalities for a more affordable price when you consider how much time it might take your in-house staff to reach the same end goal. Any time you’re paying your employees to customize your software is time taken away from their other key responsibilities.
