your users do.

How it works

Up and running in minutes

Add your sites

Paste in your URLs — production, staging, APIs, whatever matters. Takes about 30 seconds.

We check every 60s

We ping your sites around the clock and record every response, response time, and status code.

You're first to know

The moment something breaks, your team is alerted via email, webhooks, Slack, Teams, PagerDuty, Discord, Opsgenie, Telegram, Pushover, or ntfy — with setup guides built in — and your users stay informed through a branded public status page.

Features

Everything you need. Nothing gated.

Status pages, server metrics, and every alert channel are included on every plan — no add-ons, no per-seat fees. Click any feature to see it in action.

Status pages & incidents

Keep your users in the loop.

Most monitoring tools only tell you when something breaks. DownCTL also gives your customers a real-time place to go — and keeps them informed automatically at every step.

Public status page with custom branding

Enable a public status page for any site with a single toggle, then add your own domain, logo, favicon, accent color, and support link. No separate Statuspage.io subscription needed.

Full incident lifecycle management

Publish incidents publicly when they matter, walk users through every stage with timestamped updates, then close the loop with a post mortem.

Automatic subscriber notifications

Visitors subscribe to your status page in one click. They get automatic emails when an incident opens, each time the status changes, when it resolves, and when a post mortem is published.
