Monitor your servers, containers, and infrastructure in real time. Get instant alerts when something isn’t right — before it becomes a bigger problem.
No credit card required.
Get real-time visibility into your infrastructure and resolve issues faster with actionable alerts and historical data. pylon-beacon pushes CPU, memory, disk and temperature out through one outbound connection — no open ports.

One small static binary pushes vitals over outbound HTTPS every 20 seconds. No listener, no open ports, nothing to firewall — it works behind NAT, CGNAT, and networks you don't control.
Set vital rules like disk > 90% or temp > 80°C. PylonMon watches from
outside your infrastructure — so a dead host can't take its own alarm down with it.
Email, Slack, Google Chat, Discord, SMS, voice calls, webhooks and more — with escalation ladders that keep climbing until someone acknowledges.
Vitals say the box is healthy; a journey proves the business is. A real browser signs in, adds to cart and checks out on a schedule, and pages you with the failing step and a screenshot when it can't. Written in plain lines — no code, no selectors to maintain.
The classic server performance monitoring stack — Prometheus, exporters, a dashboard to babysit — means running more servers to watch your servers, opening ports, and maintaining scrape configs. A push agent inverts it: the machine reports out, so there's nothing to reach, nothing to expose, and nothing extra to host. And because the monitoring expects a heartbeat rather than answering a poll, a machine that dies takes exactly one push interval to be noticed — the dead-man's-switch per host that a scraper structurally can't give you when the network path is the thing that failed.
The agent is open source (MIT), standard-library Go, a single static binary for Linux and Windows — small enough to read before you run it. Source on GitHub →
And the same account covers what agents can't reach: website & API uptime, HTTP/S, TCP, ping, DNS, TLS-certificate and domain-expiry checks, attack-surface exposure, AI model APIs, plus heartbeats for cron jobs and backups — one system, one place that pages you.
Only for inside-the-box vitals. Uptime, HTTP/S, TCP, ping and DNS checks run from our side with nothing installed. The agent is optional, open source, and takes about a minute per machine (Linux one-liner, or a PowerShell installer on Windows).
Nearly none — it's a single small binary with no runtime and no dependencies, sleeping between 20-second pushes. It runs happily on a Raspberry Pi.
The free plan includes 3 agent-monitored servers with vital-threshold alerting, plus 20 monitors overall with 1-minute intervals. Paid starts at $9/mo — 30-second intervals, agent coverage up to your full monitor cap, SMS, and more monitor types. See pricing →
That's the normal case, not the exception. The agent only makes outbound HTTPS requests — if the machine can reach the internet, it can report in. Nothing inbound, ever.
About a minute per machine. No credit card.
