WatchAny TCP port
Monitor databases (5432, 3306), mail (25, 465, 993), SSH, message queues or any custom service by host and port.
Port monitoring
TCP port monitoring for any service
Not everything speaks HTTP. WatchControl opens a TCP connection to the port you choose — 443, 5432, 25, or any custom port — and alerts you when it stops accepting connections.
Connection checks
We confirm the port actually accepts a TCP connection — not just that the host pings — so you catch a dead service on a live box.
Checks every minute
From 5-minute checks on Free down to every minute on Pro and Business, with failure confirmation.
Instant alerts
Email and webhook on every plan, plus SMS, routed to the tools your team already uses.

Add a host and port and get alerts in minutes — no credit card.
