Uptime Monitoring

Know it’s down before anyone else does

Active checks against your hosts, every few seconds — with alerts the moment something breaks.

Monitor your domains and servers with DNS, HTTP/HTTPS, SMTP and ping checks — verified, assertion-based and alerting you via e-mail, webhook, Slack, Discord or Telegram.

Why monitoring from dremaxx

Always watching

Our probe cluster checks your hosts around the clock — from multiple source addresses.

Four check types

DNS, HTTP/HTTPS, SMTP and ping — mix and match per host, each with its own interval.

Instant alerts

Incidents open and resolve automatically and notify you on your channels.

Realtime charts

Uptime bars and latency charts update live in the console — no refresh.

In three steps

How it works

1
Verify your domain

Prove ownership once with a DNS TXT record — every host under the domain is then fair game.

2
Add hosts & checks

Create hosts and attach DNS, HTTP, SMTP or ping checks with assertions on the results.

3
Get alerted

Connect e-mail, webhook, Slack, Discord or Telegram and get notified on failure and recovery.

What you get

Built for reliable alerting

Everything you need to keep an eye on your infrastructure — without running your own monitoring stack.

DNS, HTTP, SMTP & Ping

Four probe types with per-check intervals and timeouts — from 15-second resolution depending on plan.

Assertions on results

Assert on status codes, headers, body content, DNS answers, SMTP banners and more.

TLS expiry checks

HTTPS checks track certificate validity — alert before a certificate expires.

Anti-flapping thresholds

Open and resolve incidents only after N consecutive failures/successes — no alert noise.

Five alert channels

E-mail, webhook (JSON/HTML/Markdown/Text), Slack, Discord and Telegram — per check.

Uptime & latency history

A full year of aggregated history with uptime bars and RTT charts.

Documented probe IPs

Fixed egress addresses for your firewall allow-lists — IPv4 and IPv6.

Live console

Probe results stream into the dashboard in realtime — watch checks go green.
