Pricing

First 5 servers free. Then €3 per server per month.

No tiers to compare, no price-on-request until you're above 100 servers. Everything monsys does — CVE detection, compliance evidence, AI Explain, topology — is in every plan. You only pay for the number of servers.

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 server?

Every machine running the monsys agent: a VPS, a physical server, a VM or a Windows host. Containers on a host don't count separately. Outside-in uptime checks (no agent) are unlimited.

Are there features only available in more expensive plans?

No. Free and Pro have the same features; the difference is the number of servers 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, monsys is a Docker stack you run on your own VPS; the agent and the hub are open source. Self-hosting with support and updates is part of Enterprise; if you manage it yourself, you pay nothing.
