Jira is the default issue tracker for hardware teams that run sprints alongside their mechanical and electrical work. Issues can carry a type, priority, component, and fix version, so a firmware bug, a board revision, and a test failure can all live in one backlog with the same workflow. Standard at $9.70 per user a month on monthly billing covers the first 100 users and adds team-managed projects, 250 GB of storage, and audit logs. Premium at $19.60 adds advanced planning, capacity management, and 99.9 percent uptime, which matters when a program runs across sites.
The free plan covers up to 10 users, which suits a small hardware team or a single product group. The catch is the seat-band billing: monthly prices change as the team crosses band boundaries, so a growing team should model the cost at its expected headcount rather than at the entry rate.
