When it comes to choosing the best open-source support ticket system or help desk software, there are several factors to consider. 

First, consider your specific needs, such as the size of your organization, the number of support requests you receive, and the level of customization you require. Second, consider the features and capabilities of each software, such as ticket management, reporting, and integrations with other tools.
