opensource bug and issue tracking tools for linux

Software developers and engineers alike dedicate time to designing projects to get them right. However, any project implementation is going to have unforeseen challenges and issues. Challenges are always around. However, a good measure of resiliency for any project, business model, or organization is not how well it handles things when everything is planned but when speed bumps come along.

An issue or bug tracker is a critical tool for software development and project management workflows. An issue tracker allows developers to open, track, and resolve bugs collaboratively while making it easy to track the progress. Bug trackers encompass many options focused on meeting specific needs, features, and use cases, including but not limited to software development or project management.
