For rails apps there has been rollout gem, and we’ve been using LaunchDarkly. These system wider services like LD are nice for control and uniformity and pan-system availability: being able to manage rollout of a single FF that can govnern multiple microservices at once made managing a larger cross-team feature very simple. I cannot speak to price / value, but that FF sharing was so useful at simplifying communication between teams and rollouts, which can always get tricky.
