Bugzilla

Pros: Up until about a year ago, Bugzilla was the bug tracking application used in our company.
To cut right to the chase: as a user / bug reporter, Bugzilla was a dream to work with.
It's a school book example of how great free and open source software can be.

The interface is no nonsense. Very simple and clean, everything does what you expect it to do. No need to navigate through different submenus to do even the simplest of tasks. No options hidden behind mysterious hamburger menus or gear wheel icons. The most common things are but a click away.

This implies there is no or only minor explanation needed to get started with Bugzilla. Even some of our sales guys were easily and independently filing new bugs or searching for existing bugs, and that's definitely saying something.

One of the key aspects of a bug tracker is definitely the performance of its search functionality. This is a point where OTRS definitely scores. Its search is very fast and precise. Usually, jotting a keyword or two in the "Simple Search" is enough to find exactly what you need. For the rare cases where it doesn't, the "Advanced Search" definitely does the job, while really being "advanced" but in no way "complicated".

Little secret: even though all data from Bugzilla was copied to our new bug tracker when we made the switch, I still tend to go first to Bugzilla if I need to find an old bug. Simply takes me less time to find what I need compared to our new system.

Cons: I do understand why we moved away from Bugzilla. It is merely a bug tracker.
Bugs are meant to be linked to tickets, added to sprint plannings, maybe assigned to epics together with new features. You get the point. Bugzilla wasn't made for that.
Our new platform can do it all and more, in one single system.

Overall: Creating and finding bugs in a matter of seconds, completely hassle-free.

Pros: 1. Free of cost with updates.
2. Easy of installation.
3. Browser compatible- with most of the varieties of standard ones.

Cons: 1. UI design not attractive.
2. Customization difficult.

Overall: This was the market pioneer for free-ware bug tracking. It is easy to set up and host on your office system.
Though the UI has a few things to be desired and you need to circumvent the lack of usability, but some good user training(which you will anyways be giving with process implementation with your team) helps a lot.

If you are looking for a free ware tool - esp where you need to start from scratch and have a limited budget, then look no further.

Major cons -
1. I felt the UI needs some improvement - alongwith Usability.
2. The other paid tools have good customizability - defining the workflows or even showing proper labels.

Overall Bugzilla has a proven track record of being a very good tool - esp for start-ups with less money and/or either a company or a new sub-department within the organization - where the management doesn't want to invest a lot of money.

But with good process definition and proper implementation(which will also help in long) these shortcomings can be overcome.

Though

Recommendations to other buyers: If you are on a shoe-string budget - this is God's blessing for you.

Pros: Bugzilla has been around for years and I have used it on many projects. The ease of use of logging bugs and email notifications sent automatically to preset groups to be aware of bugs. Viewing status of bugs is an ease as assigned bugs get updated by bug owners.
Another great tool included with Bugzilla is the reporting matrix, which allows the Test Lead and other Project leads to view all bugs and statuses.

Cons: The GUI is quite old looking but the web app does do what it needs to. There are more superior applications out there with more functionality and depending on what you were intending to use the application for you may opt for something like Jira.

Overall: Easily track bugs and ability to report bugs on project update.
The email notification was great to see status of individual bugs
The ease of use was a no-brainer
The cost was relatively cheap compared to others in the market

Pros: We can link so many people to an issue and any findings will be reported to all the people in the email list. The database capabilities are very optimized. I think there is no match to bugzilla when it comes to pricing, an open source alternative to our worries. We have some great login options availaible with bugzilla.

Cons: Weak support with third party tools and low integration is making it fade. However a large community always has answers to your questions, but some questions still goes unanswered.

Overall: A handy tool for beginners, good tracking of the issues and all the emails are sent perfectly for every issue. We have resolved many issues of some of our softwares with it's help. The team is happy with the information tracking on issues.

Pros: I find bugzilla easy to use with a good set of options which helped me to log defects and track them. This was extensively used in my previous workplace and the general consensus was positive. The bug status and resolution parameters with a set of APIs made it easy to have a wrapper around it and use it extensively in our automation. The notifications and search filters came in handy more often than I expected.

Cons: The UI has not aged well and looks dated. It needs a refresh which could attract more users. This tool has potential and could be used to track other issues and stories. Could be bettered to fit the agile model.

Pros: 1.Bugzilla is an Open source!
2.license fee not required
3.no limit to the number of licenses.
4.Can be easily installed as wel as maintain, except when migrating from one version to other.

3. E-mail alert feature is nice to have and good part is it is customizable

Pros: Feature and functionalities are quite good as compared to this other tool like JIRA. Various queries and number of feature provided are are self explanatory.

Cons: will be good if we can prepare "Help" Tutorial for this for new customer. This is easy to understand in current state but if a link to tutorials videos made user requires no external training

Pros: Mature software, good management of bug history, versions, for multiple products, very customizeable as well.

Cons: Automated testing not supported as built-in functions. We managed to do it with an add-on but the graohical interface for this is not intuitive.

Cons: More fields can be included to make the tracking easy. Overall the quality of the bug tracking software is good.

Pros: I thing the biggest advantage of Bugzilla is how easy it is to navigate across reported issues data.
One more thing I liked is short installation and learning curve.
We were a small project of 30 people and we needed something cheap and easy to onboard for bug tracking. We never regret we went for Bugzilla.

Cons: Only available via web UI. Works really slow via mobile browser.

Pros: It was quick and easy to report our bugs. I was able to enter the info necessary in a quick manner without spending a lot of time filling out unnecessary fields

Comments: I am using this tool from past five years and I love it

Pros: As an intern who was new to the technology development process in the real world, I found this tool to be intuitive.

Cons: The only issues that I encounter while using this tool were due to the fact that I needed to be brought up to speed on the terminology used by the verification engineers that I worked with and not related to the tool itself.

Cons: - Really outdated interface. It needs a serious refactoring.
- Importing test cases from .csv files is not straightforward.

Pros: Extremely easy user interface and feature rich product. Very easy to navigate throughout and quick response.

Cons: Found it difficult to set filters. Also faced some issues with content limit. Video are typically big in size.

Pros: I liked the simplicity of logging and tracking bugs, plus it's free to any team that wants to use it.

Cons: Unfortunately, since it's open source and free it doe look a little dated compared to something like JIRA.

Pros: It is basic and easy to use. The layout of information flows very well and it is easy to search for the tickets you need.

Cons: It could have a slightly better interface. Something more pleasing and less bland but functionally it works well for our needs.

Pros: We can log bug easily and have better functionality.
We can assign the bug to the respective person.
Developer has facility to change the resolved facility

Cons: I think UI type view of reported and resolved bug should be there.
Soeasily we can get the status of projects

Overall: Not need to keep the record of Bug in sense of excel sheet.
easily change the status of the bug. easily track the bug record.

Pros: Main benefit of this software is its open source architecture. It carries virtually no cost and very good community support which provides guidance on virtually every aspect. Notifications are good and suits your need. Advance search options and report systems are efficient and does its job well.

Cons: As its open source so customization level is not very good. Navigation to errors is tricky and complex.

Overall: A very cost effective bug tracking application which does its job well. No complaint as compared to price.

Pros: Bugzilla is a functional issue-tracking system and it is free. It can be adapted to different needs fairly easily.

Cons: The user interface is the weakest part of this system. It is rather clumsy and confusing for the normal end user. That is unfortunate because that fact seems to dissaude those end users from reporting issues.

We have since moved on to other products.

Comments: I love bugzilla

Pros: it is easy in usage and its user interface is understandable for people without technical knowledge;it easily integrates with test management instruments,it automates documentation

Cons: its interface is too sophisticated, complain that it is hard to manage the logged in errors and that there are many defects in code of this instrument

Pros: Its ease to use and install
it is an open source widely used bug tracker;
it is easy in usage and its user interface is understandable for people without technical knowledge;
it easily integrates with test management instruments;
it integrates with an e-mailing system;
it automates documentation

Cons: The UI is not that impressive, it should also contain manual for operation
If I have two products and I add a new bug to Product1, the bug number is 1.
If I then add a new bug to Product2, the bug number is sequential (ie. 2). In
this example there would be no bug number `2 for Product1. Ideally we would
want Product1 to have bug numbering sequentially specific to the product, so if there are 100 bugs for Product1 then the bugs are numbered from 1 to 100.

Overall: I was able to log the defects

Pros: I like how Bugzilla offers many options and fields to apply for a particular bug. I like how it provides advanced search for bugs to quickly navigate.

Cons: I dislike the security model. Just recently there was a big breach in Bugzilla giving the attacker privileges to see secure bugs. Also, for a big project like Mozilla, it becomes difficult to navigate bugs easily. I also do not like the default review (Splinter) that is integrated with it. Also, it does not integrate nicely with Github.

Overall: Simple to use interface runs in any web browser. Details are granular enough to convey a basic idea or a complex analysis depending on the ability and willingness of the user.

Comments: Overall, I like it a lot. Bugzilla is a great, helpful bug tracking tool and a project management platform.

Pros: I like nice user interface, It is very intuitive software, once I started using it, I did not have to put too much thought into it. I did not have to go through the training - it was easy to navigate.

Cons: I would like to see a better design, because this bug tracking system looks too plain on the front end. Some talented designers should be employed for that.

Pros: Has all the features for software development project. Integrated well with NetBeans IDE, so we can directly update tickets without opening BugZilla.

Cons: Before JIRA, this is the first choice for software development, but the UI needs some refresh to catch up with another todays software development project.

Pros: Best part of bugzilla is we can customize this as per business needs. It is a open source , free tool. only customer support and maintenance need money

Cons: As comparison of JIRA, its very less feature because JIRA supported agile fully but its doesn't. But use as per your need or convenience.

Pros: Well, the software is ugly and complicated but at least it´s free. You just need a place to host it and you´re good to go having headaches.

Cons: The interface is terrible, sometimes you will get lost in the application. You should consider this option only if you couldn´t find any other.

Pros: - Optimized database structure for increased performance and scalability

- Able to schedule reports

- Different views on bugs

Cons: - Attachments are not shown in the threads
- Difficult to track multiple threads
- Sometimes the UI is very slow, also the UI looks dull

Pros: This is decent, barebones bug management software. Easy to navigate and to browse, organise, and track bugs in software development.

Cons: Very old-school user interface. Tricky to integrate with more modern project/task management apps, although some of them are backwards-compatible with this tool.

Pros: Bugzilla is a popular software for managing defects. It supports standard features for a defect life cycle system. A developer can put estimates on time needed and then track the actual time. A developer may also put deadlines.

Cons: Features related to Agile project management are limited. At times performance can be an issue. User interface may appear a bit outdated.

Overall: The product allows testers to report issues, and developers to update testing staff and project management to update the progress on defects. Over all fairly reliable and easy to use.

Comments: It's been very instrumental and handy in tracking and maintaining the bugs. Easy to segregate bugs based on the environment type, priority and product.

Pros: excellent layout

Cons: integration with other utilities

Overall: I oftenly use this tool and has been using this for a couple of years, I like its web platform like dashboard it has provided with the great ease of logging the bugs and tracking the bugs, Very easy to track the flow of the bug.

Pros: Bugzilla has a long history as the go to bug tracking software. It's robust, full of features, and quite reputable

Cons: It's a bit complicated. Interface is archaic and doesn't cope with modern design principles, and sometimes installation and administration can be a nightmare!

Overall: It's nice, but there are better solutions nowadays

Comments: Bugzilla provides a web interface where users can enters bugs, with there resolution status, severity, platform details. It provides color coding and open source as well.

Pros: 1. User friendly bug tracking tool.
2. One of the good tool to manage whole bug life cycle.
3. Simplest basic tool available in the market.

Cons: 1. takes more time to load
2. No features for project management.

Pros: The software's major strength is that it's basic and easy to use; there's not really any learning curve.

Cons: The strength is also a weakness, as it felt somewhat barebones and spartan with such a simple interface.

Pros: At the beginning I did not know that I could set filters as simple as I did, is a great tool to track bugs.

Cons: The UI is too old stylish, it needs a better and modern design to be more like the new trends of development.

Pros: old looking
it's usable, but you surely can find better free stuff

Cons: the ui is generally ugly
I felt lost a bit too many times and tried other stuff
