Show HN: Sigabrt.dev – cronjob monitor with an SSH TUI

This tool offers a lightweight, low-friction way to monitor cron jobs and other scheduled tasks by using a simple heartbeat model: IT teams add one line to a job, and the service alerts them only when a run is missed. For CIOs and technology leaders, the business value is faster detection of silent job failures that can disrupt backups, data pipelines, renewals, and other operational processes—reducing downtime risk without adding agents, credentials, or complex infrastructure. Strategically, it reflects a broader shift toward self-serve, terminal-friendly observability that can improve operational resilience while keeping implementation overhead and vendor integration costs low.
