Leash: Spreadsheet Based PagerDuty Alternative

Leash – I built an incident management system in ~200 lines of Python, production ready.

Tired of paying per-user for PagerDuty? I built an open-source alternative that handles on-call rotation, escalation, and multi-channel alerts (Slack/Email/SMS).

Workflows that wait hours for responses survive restarts without needing message queues or state machines. And your team edits schedules directly in Google Sheets instead of clicking through admin UIs.
