The tool also generates real-time crash reports so you can compare the bugs and the crashes they led to, side-by-side. This gives insight into the way in which the bug is impacting your software. Moreover, the tool allows for bug reporting from software users.

Bugzilla is an open source bug tracking system and defect tracking tool. It assists with bug issue tracking, software issues, and any improvements that need to be made in the tool. The bug tracker keeps you updated on the status of bugs in your tool by generating a periodic or real-time bug report.

When you add a bug in the logs of Bugzilla, the system automatically scans your software for duplicate or similar bugs. This allows you to track more bugs in less time. You can also assign bugs to be fixed and keep track of the time it takes to fix a bug with the help of the time tracking feature.

Bugzilla is a completely free bug tracking tool and provides no upgrade options. However, since it’s open source, you can download the latest version of the tool when the latest updates are available online.

Zoho BugTracker

Zoho BugTracker is a free bug tracking solution. It helps you capture a comprehensive set of details required for defect management such as the status of the bug (whether it’s active or has been fixed), a description of the software bug, the team responsible for it, and the severity of its impact. Operating like an issue tracking system, you can also share these details with others by exporting them in a file format of your choice such as XLS or CSV.

Moreover, this bug reporting tool allows you to create a view of the bug based on the specific details you want to capture in your order of priority. For example, if you only want to capture the level of severity, name of the bug, and the timeline for fixing it, you can customize the fields and capture only these details. This allows you to record each bug differently based on the details required in each case.

The paid plans for Zoho BugTracker start at $3.34 (based on INR to USD exchange rate as of 19th July, 2021).


OpenProject Community is a free, open-source project management tool that can serve as a fantastic bug tracking software for your organization. Best of all, it offers unlimited users and unlimited projects.

Like Bugzilla it offers issue tracking and task management features to help programmers keep track of crucial bugs. These can be viewed in a Gantt chart view for better visualization. Time visualization can be color-coded and given different statues. Managers can see what is on time and what is in the correct development stage. They can also easily see what is coming up, allowing for better project planning. 

Time-tracking features are also available, like in Bugzilla. In combination with the Gantt charts, this becomes more useful. Users and managers can allocate time more accurately. This prevents bottlenecks and improves efficiency in project development. 

Cost tracking and product roadmaps allow developers to better manage both their time and money. This will allow them to more effectively keep track of many projects at once. Those using freelancer developers and consultants will appreciate this feature.

The user interface is far more friendly than an older tool like Bugzilla, though not as polished as a SaaS product from a vendor like Zoho. In summary, this software offers a strong host of project management and bug tracking features. OpenProject uses the benefits of open-source software to its advantage while staying accessible to more inexperienced users.
