AI-Powered uptime monitoring that
tracks, alerts & resolves incidents for you
Halvyn watches every layer of your stack — HTTP, databases, cron jobs and more — rechecks blips before it pages, summarises each incident with AI, and alerts the right person before your customers notice anything.

Diagnostic Summary
Latency spike (+380%) began 90s after the 14:30 deploy. Slow-query log shows an unindexed lookup on orders.customer_id introduced in that release.
What to check first
- Check the 14:30 deploy — failures began two minutes after it
- Compare P95 latency with the previous 7 days
- Re-run the check after the fix to confirm recovery
Pattern: failures cluster between 14:00 and 15:00 UTC on weekdays.

Intelligence built into every check
Not just uptime pings — Halvyn rechecks network blips before it pages, turns an outage into one incident, and writes the summary for you.
Detection that doesn't cry wolf
A timeout or connection reset is rechecked within the same run before it counts as a failure, and an incident opens only after your consecutive-failure threshold. When a shared dependency goes down, you get one alert, not one per affected service.
AI summaries & insights
Every new incident can carry a plain-English summary of what failed. Monitor insights compare the last 7 days with the 7 before, flag recurring failure hours, and warn of SSL expiry weeks ahead.
Automated Workflows
Instant alert routing via email, Slack, SMS, and phone with on-call escalation policies — one open incident per outage, escalated until resolved.
Early-warning rules
Alert before an outage, not after it. Rules watch P95 latency and error rate per monitor and notify Slack or email when a threshold is crossed; SLO burn alerts warn when your error budget is going too fast.
From uptime pings to insight
Halvyn doesn't just tell you when things break — it shows you the patterns behind the failures, so you can fix the cause.
Full-history health
Insights read every check in your plan's retained history — uptime, average latency and incident count — so you see the long-run picture, not just today's.
- Uptime & latency across retained history
- Per-monitor latency percentiles
- Incident count per monitor
Intelligent Pattern Recognition
Detects recurring downtime windows by hour-of-day and day-of-week — surfacing whether your Monday 2 AM deploys are the actual culprit before your engineers start guessing.
- Hour-of-day failure heatmap
- Day-of-week risk scoring
- Recurring outage detection
Trend & risk scoring
Compares the last 7 days with the 7 before, rates each monitor's trend and risk, and recommends the next step — so a slow decline is visible before it becomes an outage.
- 7-day vs prior 7-day comparison
- Trend and risk rating
- Recommended next action

Incidents & Alerts
Email, Slack & webhooks, SMS and phone calls — with on-call escalations.
One incident per outage.
Escalated until it's fixed.
When a monitor crosses its failure threshold, Halvyn opens exactly one incident — no alert storms. It escalates across channels, then auto-resolves and records the full timeline the moment service recovers.
- Deduplicated — one open incident per monitor
- On-call rotation escalation policies
- Auto-resolve with timeline & post-mortem notes
- One-click acknowledge via email link

One pulse from failure to fixed
Every outage rides the same automated path — no runbook lookups, no manual triage, no forgotten tickets.
Detect
A failed check is rechecked within the same run, and an incident opens only after consecutive failures — a single blip never pages anyone.
Summarise
AI writes a plain-English summary of what failed and when, attached to the incident.
Auto-Resolve
One incident per outage. The moment service recovers it closes itself, with the full timeline attached.
Notify
The right person, on the right channel — email, Slack, SMS or voice — escalated until acknowledged.

You get alerted
The AI incident engine opens one incident per outage and escalates across your channels until resolved.
Flat price vs. per-host metering
The difference is not the sticker price — it is what happens to it as you add monitors.
| Monitors you run | HalvynFlat | Typical per-host toolMetered |
|---|---|---|
| 10 monitors | CustomTalk to us | ~$70/mo |
| 50 monitors | CustomTalk to us | ~$350/mo |
| 200 monitors | CustomTalk to us | ~$1,400/mo |
| How it is priced | One flat price per plan | Per host, per check and per feature |
| Monitor types | All 10 check types on every paid plan | Synthetics and database checks cost extra |
| Alert channels | Email, Slack, webhooks, SMS, escalations | Commonly sold as add-ons |
| Next month’s bill | Identical, unless you change plan | Depends on what you added |
Illustrative. The metered column is modelled at $7 per monitor per month, mid-range for per-host and per-check vendors. Real pricing varies by vendor, region and configuration.
Incidents land in Slack before you look up
Down and recovery alerts, with an AI incident summary and a link to the incident — posted to the channel you choose.
✅ RESOLVED: api-gateway latency returned to normal. Incident duration: 4m 12s.
🔴 checkout-api is DOWN
Cause: HTTP 503 from origin, after 2 consecutive failed checks
Summary: Latency rose from 204 ms to 2.9 s before the 503s began.
🟢 checkout-api recovered after 2 passing checks. Downtime: 4m 12s.
AI incident summary
A plain-English summary of what failed and when is attached to every new incident.
One-click acknowledge
Every alert email carries a one-click acknowledge link that stops further escalations.
Down and recovery
Each outage posts when it starts and when it recovers, with the downtime, so #alerts tells the whole story.
