We're building Vibe OnCall - the AI-native pager that replaces PagerDuty and Opsgenie. We retired the physical pager in 2001. It's time to retire the digital one. Every on-call engineer knows the 3am page. Alert fires, you're awake, and you spend the next 40 minutes figuring out what broke before you can start fixing it. We killed that part. Vibe OnCall pages an army of AI agents that triage, find root cause, and write the post-mortem - before Tier 1 ever wakes up.
