Haystack aggregates activity in git to give engineering managers more visibility into how their team's work. We came up with the idea when we realized how difficult it is to answer a simple question: 'Is the team doing better than we were 6 months ago?'. We realized how hard it is to not only visualize trends on their team but get actionable insights into the biggest areas to improve. Whether it's spending too much time in code review, taking on too much concurrent work, or even getting bogged down with technical debt; we wanted a tool that can not only help to spot issues but also alert us so we can take action. Introducing Haystack.
