Monitoring & Observability
Cron job monitoring that alerts when a ping goes missing. Free for 20 jobs, open source and self-hostable.
Your job pings a URL. If the ping stops, you hear about it. Healthchecks.io watches scheduled jobs by waiting for a ping. Your cron job, backup or script calls a URL (curl is enough) when it starts, finishes or fails, and Healthchecks.io alerts you if the ping does not arrive on time. The Hobbyist plan is $0 and covers 20 jobs with 100 log entries per job. Business is $20 a month for 100 jobs and 1,000 log entries per job, and Business Plus is $80 a month for 1,000 jobs, with 20 percent off for annual billing. The page says Business is free for open-source projects and nonprofits on request. Users describe it as simple, cheap and reliable, and note it is open source with a self-hosted option. The Capterra reviews I saw were all vendor-referred with an incentive.

The free plan is built for hobby and personal use: 20 jobs and 100 log entries per job. The pricing page offers the Business plan free to open-source projects and nonprofits, which is a real perk if you qualify. It is a ping-based check. If a job does not call in, you get an alert. That fits cron jobs, backups and scheduled scripts well. It does not replace an uptime monitor that probes your public site. The pricing page does not state a card requirement for Hobbyist, and I did not find a commercial use clause. The open-source and self-host claims come from reviewers and forum posts, so check the project repository for the licence before you deploy.

Pricing page read. Capterra, Hacker News and Reddit read as excerpts. The $5 entry in the page text could not be tied to a plan name and is not listed. Card requirement, licence and commercial use not confirmed.
