Edit 1: There are changes for OTRS in 2021. On 1 Jan 2021, OTRS 6 community edition would not have new security updates. Also, the GitHub repository for OTRS 6 community is archived. So, there is no official support for OTRS 6 community edition any more.
Edit 2: Phabriactor stopped being maintained after June 2021.
Introduction about bug and issue tracking software
I had to admit I liked Atlassian Jira as a bug and issue tracking software. However, Atlassian had announced that when it's in 2021 February, the standalone server version would be gone. Also, there would be a price increase of all the existing data center version.
So let's look at other alternatives. In this article, I would briefly describe several open source and low cost bug and issue tracking applications. We would have a summary of each product after the table.

Bugzilla is a rock solid bug and issue tracking software. It was originally developed and used by Mozilla project. It was released since 1998. It is used by many companies and open source project, like Mozilla Foundation, Linux Kernel, Red Hat, Apache and etc. If you look at the release timeline , you would notice it had fewer major release after 5.x (2016). So, the product is already very stable, but on the other hand it seems that it don't have major development going on.
Redmine is an integrated project management and issue tracking application. It supports multiple projects, having Gantt chart, calendar, wiki per project and more. It is written in Ruby in Rails. You may have problem if your distribution always install the latest Ruby programming language. So, I suggest to use Ruby Version Manager to fix the Ruby version.
Request Tracker (RT) version 5 has an updated and responsive UI, it also have a dark theme. It has a graphical lifecycle creater, which is unique among other applications that we had introduced in this article. Looks like RT still wanted to modernize itself and would have active development in the near feature. RT looks promising to me.
Mantis Bug Tracker
Mantis BT is a full fledged bug and issue tracking system. It has full text search, audit trails, wiki documentation integration with some wiki systems and etc. So, it is capable to be used a project management tool.
Phabricator was originally a tool used by Facebook internally. The principal developer Evan Priestley left Facebook to continue Phabricator's development. Besides bug and issue tracking use cases, Phabricator is very good when used as a code review tool and with very strong SCM integration.
Edit: Phabriactor stopped being maintained after June 2021. I am not sure if there are other forks or clones to keep this application maintained.
The OTRS software was backed by OTRS Group. Previously, the community edition could keep up with the commercial edition. However, it is not the case in recent releases. The community edition stops at OTRS 6.x, whereas the commercial edition is now at OTRS 8.x. Personally I would prefer choosing another open source solution if I want to use an open source bug tracking software.
Roundup Tracker is the only software in this article that is written in Python. It does not have a fancy UI. But, it is used by Python programming language as their bug tracking application. If you have preference or requirement to use Python for hosting the bug and issue tracking software, Roundup Tracker is for you.
Well, Jira is a closed sourced application. It is great and used by many companies and projects. However, Atlassian has changed their pricing strategy in 2021 February. Standalone server version of all Atlassian products would be gone. The data center version of the Atlassian applications would have a price increase. They want you to migrate to cloud. Their cloud version of Jira is always free for 10 or less users. But you cannot own your data. It could be a problem for some people or projects.
Besides the list of applications that we had come across in this article, there are still lots of options out there. Like GitHub, GitLab, Gitea, Tuleap, Pagure and etc.
