Although an open source time tracking software comes with benefits such as cost-effectiveness and flexibility, it can have significant disadvantages. We’ll look at some key disadvantages in the next section. 

3 major disadvantages of using an open source software

Here are the three disadvantages of using an open source time tracking software for your team:

1. Product vulnerability

The source code of any open source software is available to many people. Some users may utilize this access to spot defects and make improvements to the software. 

However, malicious users can use their access to exploit the product’s vulnerabilities and create bugs that affect the software’s performance and compromise your data. 

2. Lack of a user-friendly interface

An open source software is usually catered to the liking of the developer. And because most of these open source tools aren’t profitable, they don’t emphasize an intuitive user experience. 

This factor can make open source software unsuitable for your team, especially if you have team members that aren’t tech-savvy. 

3. Lack of extensive customer support

Open source software is mostly created by numerous developers. As a result, users don’t know who to hold accountable if there’s an issue with the software. 

Additionally, open source software typically doesn’t have an extensive customer support team. In most cases, you’d have to depend on an online community forum to get your issues resolved. 

Now that we’ve discussed the cons of using open source software, you may be wondering: 

Is there a better time tracking tool that offers the advantages of open source software without the drawbacks?
