exit1.dev is real-time uptime monitoring built for developers, agencies, and indie makers shipping fast.
Most monitoring tools show you a stale "last checked 3 minutes ago" timestamp. exit1.dev streams every check to a live WebSocket dashboard that paints results in under a second, with per-stage timing (DNS, connect, TLS, TTFB) so you see exactly where things slow down.
Nine check types on one engine: HTTP/HTTPS, push-based heartbeats for cron jobs and workers with no public endpoint, DNS drift detection, ICMP ping, TCP/UDP, WebSocket, redirect chains, and domain-expiry. Detection runs as fast as 15 seconds from multiple regions, with peer confirmation to kill false alarms before they page you.
Alerts hit email, SMS, Slack, Discord, Teams, webhooks, Pushover, PagerDuty, and Opsgenie. You also get public status pages, embeddable badges, and an MCP server (exit1-mcp) that lets Claude, Cursor, or any AI assistant query your monitoring data directly.
Free tier, no credit card. Paid plans from $7/month.
