Live monitoring that actually streams

Every other uptime tool we audited (Pingdom, UptimeRobot, Better Stack, Checkly, Hyperping, StatusCake) calls itself real-time, but the dashboard refreshes on a 30–60 second timer and re-renders from a polled API. Exit1's Live Checks stream individual probes from the VPS worker into your browser over a dedicated WebSocket transport. A probe finishing on the wire shows up on your chart in p50 well under a second — there is no polling layer.

All eight: HTTP/HTTPS, heartbeat, DNS, ICMP, TCP, UDP, WebSocket, and redirect. The per-stage phase view (DNS → Connect → TLS → TTFB) is most useful for HTTP-family checks where every probe captures all four stages; other check types fall back to total response time.

The visible window keeps filling live, but the brush navigator below the main chart shows the entire buffer — you can drag it back to a 24-hour view, drag-zoom into a specific minute, and click the spike to highlight the corresponding row in the raw probe table. Or just export the visible window as CSV/JSON.

The server holds a 5-minute replay ring buffer per region. When the socket reconnects, you get a fresh state snapshot plus any state transitions you missed during the gap — filtered to your verified user. If the WebSocket stays down longer, the UI silently falls back to Firestore onSnapshot with an 8-second debounce to prevent flicker, and a banner names the affected region so you know you're in fallback mode.

Yes. Download visible-window or full-buffer probes as CSV or JSON, with presets from 5 minutes to 24 hours. The exported payload includes per-stage phase timings (DNS / Connect / TLS / TTFB), status codes, response times, and any state-segment events (maintenance start/end, disabled start/end) that fell inside the range.

Most "real-time" features run a 30-second polled check and then auto-refresh a dashboard every 30–60 seconds. That's still 30–60 seconds of UI lag on top of detection lag. Exit1's Live page streams the probe payload itself — about 30 bytes on the wire — so the only lag is the network hop from Frankfurt or Boston to your browser. The chart, the phase breakdown, and the table all update in the same frame.

Free users see a blurred preview of the Live page with an upgrade overlay. Streaming is available from Nano upward. All paid tiers stream with no rate-limit on the WebSocket transport.

No. The wire format is roughly 30 bytes per probe. A check running every 15 seconds (Agency floor) is about 7 KB/hour per check — small enough to leave open in a background tab indefinitely. A 30-second app-level keepalive plus protocol-level ping/pong keep the socket honest without adding meaningful overhead.
