Downdar watches your websites, APIs, ports, SSL certs, and DNS from 6+ global checkpoints, and pages you the second something breaks. Ping-based heartbeats catch cron jobs and background tasks that fail silently. Alerts hit Slack, Discord, Telegram, Teams, webhook, or email, with automatic recovery notices. Embeddable status pages keep customers in the loop without extra design work. Free for 30 days, plans start at $9/month.
