Features / Browser synthetics
Synthetic browser monitoring
A page can return 200 and still be broken. Browser monitors drive a real Chromium through the steps your users take and fail when any step does.
What Halvyn checks
- Multi-step flows: navigate, click, type and wait for selectors
- Assertions on what is actually rendered on the page
- Per-step timeouts so a hang is reported as a failure, not a stall
Common uses
- Sign-up and login flows
- Checkout and payment pages
- Single-page apps where the HTML shell always loads
Included with every monitor
One incident per outage
Repeated failures roll into a single incident with a timeline, instead of a flood of duplicate alerts.
Blip recheck
A failed check is re-run within the same cycle before it counts, and an incident opens only after consecutive failures — a single network blip never pages anyone.
Escalation until acknowledged
Email, Slack, Microsoft Teams, Discord, Google Chat, webhooks, SMS, voice calls and on-call rotations — with one-click acknowledge links in every alert.
Incident management
Investigating → identified → monitoring → resolved states, assignees, comments, SLA timers per severity and postmortems.
Public status pages
Uptime bars, live incidents and manual updates on a page you can put on your own domain.
Maintenance windows
Checks keep running during planned work but alerts stay quiet, so your history stays complete.
SLOs and monthly SLA reports
Track objectives per monitor and email an uptime report to owners every month.
Flat pricing
Every check type on every paid plan, one price per plan — no per-host, per-check or per-feature metering.
