All the website monitoring tools you need — know what's broken before anyone else does.
Six monitor types. Multi-location checks. Incident management. Public status pages. SLO tracking. All in one tool, built for freelancers and agencies.
Six ways to watch your stack
Each monitor type is purpose-built for a different failure mode — so you catch the right problems, every time.
HTTP Monitoring
Know the moment your site or API stops responding.
Beaconmon checks your URLs every 30 seconds (Business) or 1 minute (Pro). If the response is anything other than a 2xx, you're alerted within 60 seconds. Set custom request headers, follow redirects, and configure per-monitor response-time thresholds to catch slow sites and APIs before users notice.
- Response code validation
- Response time thresholds
- Custom request headers
- API endpoint monitoring
SSL Certificate Monitoring
Never let an expired cert take you by surprise.
SSL expiry is one of the most embarrassing and preventable causes of downtime. Beaconmon watches every certificate and fires tiered alerts at 30 days, 14 days, and 7 days before expiry — giving you plenty of time to renew without scrambling.
- 30-day early warning
- 14-day and 7-day reminders
- Certificate validity checks
- No config needed
Domain Expiry Tracking
The worst outage is one you could have prevented.
Domain renewals slip through the cracks — especially for client sites you manage. Beaconmon checks WHOIS records and alerts you at 30, 14, and 7 days before the domain expires. No more panicked domain rescues.
- WHOIS-based expiry detection
- 30/14/7-day alerts
- Works on all TLDs
- Per-domain alert channels
TCP Port Monitoring
Monitor any service that speaks TCP.
Not everything is a website. Database servers, mail servers, game servers, custom APIs — if it listens on a TCP port, Beaconmon can watch it. You'll be alerted the moment a port becomes unreachable, before your users hit a connection error.
- Any TCP port
- Works on private IPs via VPN probes
- Sub-60 second alerts
- Works alongside HTTP monitors
Keyword Monitoring
Verify your pages say exactly what they should.
A 200 response doesn't always mean everything is fine. A broken deploy could serve an empty page, a database error, or a maintenance placeholder. Keyword monitoring checks that a specific string is present (or absent) in the response body — so you know the page actually loaded correctly.
- Keyword present or absent
- Case-sensitive matching
- Works on any HTTP response
- Combine with HTTP threshold checks
Content Change Monitoring
Know the instant a page changes.
Track competitors' pricing pages, product listings, legal terms, or any public web page. Beaconmon takes an HTML snapshot on first run and alerts you the moment the content at a CSS selector (or the full page body) changes. Perfect for competitive intelligence and change detection.
- CSS selector targeting
- Full-page or partial diff
- HTML-only (no JS rendering needed)
- Snapshot history with diff view
One blip won't wake you at 3am.
False alarms erode trust in your alerting system. Beaconmon confirms failures from multiple geographic regions before firing an alert — so when you get a notification, it's real.
- Checks from US East, US West, EU West, AP Southeast, SA East
- Alert only fires when 2+ locations confirm failure
- Per-region response times visible in the dashboard
- Available on Pro and Business plans
A status page your clients will actually trust.
Clients shouldn't have to email you to find out if their site is down. Give them a public status page — at your own domain — that shows real-time uptime, incident history, and scheduled maintenance. It looks professional, and it takes two minutes to set up.
- Custom domain (status.yoursite.com)
- 90-day uptime history bars
- Active incident banners
- Scheduled maintenance windows
- Embeddable status badge (Markdown + HTML)
- No Beaconmon branding on paid plans
Know your error budget before it runs out.
Set a per-monitor uptime target (e.g. 99.9%). Beaconmon tracks your error budget in real time and fires fast/slow burn-rate alerts when you're consuming it too quickly — so you can act before the SLO period is blown.
- Per-monitor SLO targets (e.g. 99.9%)
- Error budget tracking in real time
- Fast and slow burn-rate alerts
- Available on Pro and Business plans
