Updated: Sep 15, 2019

Bug Tracking is an integral part of end to end software development life cycle. May it be unit testing, system integration testing or user acceptance testing, tracking bugs till closure is pivotal to successful and on time software releases.

There are many paid as well as free (open source) defect tracking tools available out there in the wild, and narrowing down to one needs a bit of research. One can track bugs using a simple spreadsheet or choose to go ahead with a feature rich bug tracking software like BugZilla, Redmine, JIRA, YouTrack, FogBugz or MantisBT.

Open source bug tracking tools like Bugzilla, MantisBT and Redmine are freely available and are used by individuals as well as large scale enterprises for bugtracking. There are companies who provide premium support at a nominal fee and take care of the initial setup, configuration, onboarding, and handle any issues later on. Basic support, however is provided by the community of developers, free of cost.

On the other side of the spectrum are paid tools like JIRA, YouTrack, FogBugz, HP ALM and IBM Rational Quest that target small, medium as well as large scale enterprises.

Apart from these traditional bug trackers, there are other tools like Usersnap and airbrake.io that bring in innovative ways to capture and report issues. Usersnap for example takes snapshot of the browser and sends it to the development team. Visual communication eases out tester’s task of describing the issues.

Airbrake.io on the other hand captures exceptions from the logs as issues and links those back to the code, greatly reducing developer’s efforts to go through logs and finding out code that needs a fix.

Which one should you go for? This is a question that you need to answer based on your overall IT infrastructure, project needs, team size, and budget at hand. You might need to try a few before narrowing down to the final one.


Before we get into details of the top 10 bug tracking tools, here is a little insight into why we need such tools in the first place and what are the key features to consider for selecting a top class bug tracking software.

Why to Use Bug Tracking Tools ?

Software testing many a times is highly underrated and conducted without proper strategy, tools and team. Bugs are communicated and reported verbally, over emails or by using excel sheet. This eats up extra time and work only for very small scale projects developed by individuals or couple of developers.

When it comes to medium or large scale software development projects, you need sophisticated defect tracking tools for organized reporting and timely releases. Multiple teams’ record bugs, usability improvement requests and new feature requests during various phases of the software development cycle, and this is where bug tracking tools come to the rescue and act as a single repository.

In terms of utility, modern defect tracking tools typically overlap with project management tools or at least integrate with project management tools. Development managers use these tools for release planning, progress tracking, developer productivity, and first pass yield reporting etc.

What are the Key Features of Bug Tracking Software?

High end bug tracking tools offer features that make your bugs tracking and management process an absolute breeze. Some of the key features of such tools are as listed below –

  • Intuitive user interface and efficient reporting
  • Flexible Workflow to track bug from initiation till closure
  • Developer tools integrations
  • Prioritizing Backlog and Sprint Planning

Let us look at the best bug tracking tools that are feature rich, easy to use, and popular among the software developer and testers.

Bugzilla – Best Defect Tracking Tool (Free Tier)

Bugzilla is the baby of Mozilla foundation and was created back in 1998 by Terry Weissman to track bugs internally for Netscape suite of products. It was soon made available as open source and many organizations started to use Bugzilla as defect tracking tool for small as well as large scale development projects.

Bugzilla tops the list of open source bug tracking tools and ranks ahead of Redmine, Trac, Gitlab and MantisBT in terms of features, active development, future plans as well as community support.

The popularity and adoption of Bugzilla as defect tracking software can be gauged from the fact that large projects and organizations like Eclipse, Gnome, RedHat, Apache, W3C, North Carolina state University etc. are using Bugzilla for one or other of their projects.

Airbrake is a different animal altogether and I love the concept of Airbrake.io’s bug tracking system. The key feature of Airbrake.io is that it auto captures exceptions from the logs and puts those in task list or queues.

Apart from the ability to analyze logs, find errors and logging tickets, Airbrake has many other features of typical workflow based defect tracking tools as well.
