Mantis supports all types of document uploading that will give developers or QA to verify and identify any reported defect very quickly. The email notification function in Mantis is handy and make thing easier. Mantis is free and open-source. Using Mantis, I can track every stage in the software testing cycle. Mantis is well tested and maintained beautifully by the creators. Mantis is a widely used defect tracking tool all over the world. The main features I like most are user management, summary, mail notification, and exporting part. Review collected by and hosted on G2.com.
