Keep an eye on your ports — without constantly looking.
Portchecks automatically monitors whether your server ports are open or closed. You get an email the moment a check deviates from its target state — otherwise we stay silent.
Everything you need for reliable port monitoring.
Clear, simple and reduced to the essentials: port reachable or not, alarm on or off.
Central server management
Create as many servers as you like — each with label, IP address and notification email.
Monitor any port
Define as many port checks per server as you need — each with target state and interval.
Automated scheduler
Our scheduler runs every minute and reliably dispatches due checks to the queue.
Alerts only when needed
You only receive an email when the desired target state is not met — no noise.
Multi-tenant
Every user only sees their own servers and checks. Strict isolation.
Scalable queue workers
Production runs multiple Redis queue workers in parallel — even thousands of checks are no problem.
From zero to monitoring in three steps.
From sign-up to first automated check in under five minutes.
