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

This describes a lightweight cronjob/heartbeat monitor that notifies you when scheduled pings from your scripts fail to arrive. You create an endpoint, specify how often it should report and a grace period, and get a single ping URL to curl at the end of a successful job. If an expected pulse doesn't show up on schedule, the service sends an email (or ntfy) alert; silence means everything is working. The site shows a typical crontab example with a curl at the end of a backup script and highlights that no agent, library, or credentials are required. A free tier offers 10 heartbeats without a card.

Operationally it exposes a terminal UI over SSH: add your SSH public key, ssh in, and see each endpoint’s status, schedule, and recent events in a read-only TUI while the project is still evolving. Status labels include ok, grace, and down with timestamps for last pings and missed pulses. Features called out include alerting, 1-minute minimum intervals with configurable grace, and 90 days of history. Pricing is a single plan - €15/month - for unlimited endpoints and heartbeats, with the option to start on the free tier.
