Pricing

First 5 systems free. Then from €2 per monitored system per month.

One unit: the monitored system. A server costs €3, a WordPress or Drupal site €2, a cloud account €5 per month. Everything monsys does is in every plan; you only pay for what you monitor. The first five systems are free, forever.

Questions about pricing

Is the free tier really permanent?

Yes. Five servers are free with no time limit and no card. It's not a trial: it's the plan we want every sysadmin to start with.

What counts as a monitored system?

A server running the monsys agent (VPS, physical, VM, Windows host; containers do not count separately), a website connected and verified through the monsys plugin, or a cloud account with discovery enabled. Uptime checks and status pages do not count and are unlimited.

How are the 5 free systems allocated?

Automatically to your most expensive systems: cloud accounts first, then servers, then websites. Two servers and three websites are therefore entirely free; ten websites cost €10 per month, five free and five at €2.

Are there features only in more expensive plans?

No. Free and Pro have the same features; the difference is the number of systems and retention (7 versus 90 days). Enterprise adds self-hosting, dedicated hosting, custom retention and an SLA.

Can I self-host instead of using the SaaS?

Yes, as part of Enterprise, with support and updates. monsys runs as a Docker stack on your own VPS. The agent is MIT-licensed; opening the hub source is on the roadmap.
