What is Bugzilla?

Bugzilla is an open source, 100% free tool, popularly used by software engineers from the whole world wide. It is used for tracking the bugs and debugging them by many professional companies. Bugzilla was released by Mozilla in 1998. It is completely written in Perl and it uses MySQL as a database. It is licensed under Mozilla Public License, this tool is preferred by many software engineers and developers. The current stable version of this tool is 5.0.6. It was released on February 9, 2019. Although, there is no such new features added in the latest stable version. However, it is under active development by Mozilla and many new features might be included in this tool soon.

Why should one use Bugzilla?

Whenever we decide to use a tool for certain action, it always comes in our mind why should we choose that one when there are so many options in the market in these days. Let’s look further and find why Bugzilla is different than other tools in the market.

Bugzilla is totally free. It doesn’t require any license to use. Anybody can use it for any purpose without paying for anything. This is a plus point for those who have just begun their career in this field and do not want to spend a large sum of money.

Bugzilla has been around since a long time, there are tons of videos and tutorials available on the internet which makes it very easy to understand and implement. Many software engineers heavily rely on Bugzilla for debugging.

One can have easy communication as Bugzilla enables communication with the teammates.

Bugzilla is developed in LAMP which is short for LINUX, APACHE, MySQL and PHP.

Quality is assured in Bugzilla. Moreover, it keeps track of bugs and changes made in the code.

Differences between JIRA and Bugzilla.

JIRA is another tool used extensively by software engineers and developers. There are many differences between JIRA and Bugzilla. Let’s discuss them in detail be- low.

  • Created by an Australian company named Atlassian JIRA allows debugging, bug tracking and agile project management. On the other hand, Bugzilla was created by Mozilla foundation in 1998.
  • JIRA is free to some extent. In order to access the full developer version, you must have to buy a license. However, Bugzilla is 100% free to use and open source web developing tool.
  • Server-side architecture of JIRA are based on MySQL, Oracle, PostgreSQL, Tomcat, J2EE and Lucene. On the other side, Bugzilla is based on MySQL, Oracle, PostgreSQL and Perl.
  • The server load is low in case of Bugzilla. In contrast, Jira has a considerable amount of server load.
  • Drag and drop task prioritization is available in Jira which allows user to drag and drop to organize and prioritize their work. However, this feature is not available in Bugzilla.
  • Scrum feature is available in Jira. This feature allows the user to arrange their work into small, feasible pieces that can be completed in a given amount of time called sprint. But scrum feature is not available in Bugzilla.
  • Kanban feature is one of the best features of Jira. This feature is much like scrum but the only difference is that the work arranged for the sake of efficiency. This feature is also unavailable in Bugzilla.

Disadvantages of using Bugzilla

There are many bug tracking devices in the market right now. Bugzilla is one of them. But like every tool, it has both advantages and disadvantages. Let’s dig deeper and talk about its disadvantages.

There are not many features available in bugzilla as compared to other bug tracking tools. The lack of features is a big reason why software engineers do not prefer it.

There is a limited documentation on bugzilla available. However, there are a lot of videos and tutorials available on the internet about this because this tool was released a long time back and software engineers are still using it.

Many users of bugzilla has complained that it can be really slow sometimes. Moreover, it takes a lot of time to shift from one screen to another.
