Best open-source bug tracking tools

In the past decade, we have witnessed a massive increase in software development. Every industry now uses some software/web-based service in its daily operations. But with such a surge in software development, there also comes a risk for greater disasters, bugs. Fortunately, there are web-based bug tracking tools and issue management systems that enable developers to efficiently fix bugs.

The biggest challenge that developers face while building software or application is ensuring that it works with no issues/bugs. Only after fixing the bugs, you can deliver the end-user an efficient service that provides an amazing user experience. 

In this blog, we are going to look at some of the best free open-source bug tracking tools that can help deliver a fully optimized and bug-free software service.
