What is the best test management tool for Jira?

It depends on the process. Xray (25,243 Data Center installs, 4.3 stars on the Atlassian Marketplace, 5 October 2026) suits dedicated QA teams with test plans and CI automation. Easy8 suits teams that run manual test cases inside delivery projects and want them next to tasks, Gantt and time tracking, with no add-on.
