Nothing breaks loudly. It breaks quietly, at 2 a.m.
Most outages don't announce themselves. A certificate expires. A payment provider changes something. A DNS record gets fat-fingered. Your site looks fine from your desk — and meanwhile, customers are walking away.
You run an online store
Saturday night, your checkout silently stops accepting cards. Ads keep spending, carts keep filling, nothing completes. By Monday it's not a bug — it's a week of revenue.
Watch the checkout flow itself, payment endpoints, SSL, and page speed — slow stores lose carts before broken ones do.
You're an ISP or hosting provider
When something degrades, your customers notice first — and every support ticket is someone deciding whether to leave. The hard part isn't knowing something is wrong; it's knowing where: your network, their config, or the internet in between.
Checks from many regions, DNS, mail server and blacklist status, and the actual network path show you which it is — before the phone rings.
You operate infrastructure that reports for a living
Solar parks, meters, IoT fleets. If the metering API stops answering, no one sees a blank page. You just quietly lose the data you're required to report.
A simple check that the API answers, returns real data, and its certificate isn't about to expire covers the failure no one is watching for.
Different businesses, same pattern: the things that cost the most break without a sound. Monitoring is just someone always listening.
Start with one check on the thing that would hurt mostMonitor every layer of your stack
Websites, APIs, certificates, domains, DNS, page performance and the services behind them — checked continuously from regions around the world. When something breaks, you get one confirmed alert with the detail to fix it, not a flood of false alarms. And the built-in AI assistant can set up monitors, dig through incidents and tune alerting straight from a chat.
HTTP/HTTPS Monitoring
Websites and APIs checked the way your users reach them: status codes, response times, redirects and page content. If the answer is wrong or slow, you hear about it before they do.
SSL Certificate Monitoring
An expired certificate takes your site down as surely as a dead server — browsers just call it “not secure”. Track validity, chain issues and expiry, with warnings long before the deadline.
Domain Expiry Monitoring
The quietest way to lose everything: the domain lapses, and the site, email and brand go with it. WatchFor reads expiry straight from the registry and warns you weeks ahead.
DNS Monitoring
When DNS is wrong, everything is down — even though every server is up. Watch A, AAAA, CNAME, MX and TXT records for unexpected changes, resolution failures and propagation issues.
Core Web Vitals Monitoring
Slow is the outage nobody alerts on. Scheduled Lighthouse audits track LCP, CLS and INP over time, so you catch performance regressions — and their SEO cost — before your rankings do.
TCP Port Monitoring
Databases, mail servers, brokers — anything that speaks TCP. Connection checks with optional banner reads keep the services behind your website as watched as the website itself.

What's new in WatchFor
Alert notifications now group during incident storms
When one underlying problem takes several monitors down at once, your chat and email channels now receive one clear summary — "🔴 10 new incidents" with the affected monitors listed — instead of ten separate pings. Monitors failing one by one batch too: follow-up waves collect for a few minutes and arrive as one further summary, and recoveries group the same way. A lone incident still arrives promptly as a normal, fully-detailed notification, and PagerDuty, Opsgenie and webhooks keep their exact per-incident behaviour.
Mute a monitor's alerts + smarter flap suppression
You can now mute a monitor's notifications for 1h/8h/24h/7d — from its ⋯ menu or straight from a firing incident. Checks keep running and incident history keeps recording; only the pings pause. Muted monitors carry an amber badge and a Muted filter in the monitors list, so a silenced monitor is never lost among hundreds. Also fixed at the engine level: a rapidly flapping monitor now stops paging until it stabilises, and warning alerts stay quiet while the same monitor's critical incident is already firing.
8 new notification channels — from Opsgenie to Zapier
Alert routing now reaches eight more places your team may already live in. Opsgenie joins PagerDuty on the on-call side — firing incidents open an Opsgenie alert and recoveries auto-close it, with US and EU regions supported. Google Chat, Mattermost and Rocket.Chat join Slack, Discord and Teams for chat delivery (each a one-webhook setup). Gotify, Pushover and Pushbullet join ntfy for phone and desktop push. And Zapier connects alerts to 5000+ other apps via a Catch Hook. Add them under Alerting → Channels.

Heartbeat & Cron Job Monitoring: the Dead Man's Switch Your Backups Deserve
Most monitoring checks that something is up. Heartbeat monitoring does the opposite — it alerts when something that should run goes silent. The concept, who needs it, and how to set it up so a dead backup job can't hide for three weeks.
MCP Server Monitoring: Why "HTTP 200" Means Nothing to an AI Agent
MCP servers fail in ways no uptime check can see: the port answers 200 while the handshake breaks, tools vanish, or a tool description is silently rewritten under your agents. Here's how protocol-level MCP monitoring works — and why we built it.
Advanced SSH: jump hosts, tunnels, and power-user tricks
Once you know basic SSH, a whole toolbox opens up: jump hosts to reach private servers, port forwarding, SOCKS proxies, agent forwarding, and a config file that makes it all effortless. The power-user guide.
