The best feature that Rootly offers, which I really appreciated when we onboarded Rootly, is the shadowing feature. I evaluated quite a few tools but Rootly was the only one at the time that had this, and this allowed us to onboard new engineers into the on-call rota smoothly, which was a really cool feature. Regarding how the shadowing feature helped with onboarding new engineers, rather than manually tweaking schedules to try to hack a way to shadow existing engineers, Rootly gave us a shadow feature which allowed us to say person X, please shadow person Y, using these times and these days, very customizable, and it allowed us to onboard people in a much more graceful manner.
