The models' case: Built Slack-first from the ground up — declare, page, ack, and run the whole incident inside Slack with no context-switching. The models' main caveat: Priced and shaped for funded startups/scale-ups. The strongest alternative is Rootly — Also Slack-native by design with a mature workflow/automation engine, flexible on-call schedules and escalation policies, and deep incident tooling.
