Healthchecks.io

Healthchecks.io 是给定时任务做心跳监控的服务，逻辑很直接：每个 cron 或后台任务拿到一个专属 URL，跑完就 ping 一下，超时没 ping 就按设定的宽限期发告警。它不做指标也不做日志，只回答一个问题，这个任务到底跑了没有、跑成功没有。可以给同一任务配多个通道（邮件、Slack、短信、webhook），维护窗口能临时静音，失败后能看历史 ping 记录。开源可自托管，官方版有免费额度。 ⭐ GitHub: healthchecks/healthchecks — 10k stars 🔗 文档: https://healthchecks.io/docs/

Healthchecks.io is heartbeat monitoring for scheduled jobs, and the logic is plain: each cron or background worker gets its own URL, pings it when it finishes, and if the ping does not arrive within the grace period an alert goes out. It does not collect metrics or logs; it answers one question, did this job run and did it succeed. Per-check integrations cover email, Slack, SMS and webhooks, maintenance windows mute temporarily, and the ping history shows what happened after a failure. It is open source and self-hostable, with a free tier on the hosted side. ⭐ GitHub: healthchecks/healthchecks — 10k stars 🔗 Docs: https://healthchecks.io/docs/
