From Zabbix to Fivenines in an afternoon
“Fivenines was up on 100+ of our servers in 40 minutes. During our last major outage it was the only platform that actually pointed us to the root cause. We're now at 300+ servers monitored, and we use Fivenines as part of our sales pitch with new clients.”

Everything you need to monitor infrastructure
Server metrics, uptime checks, cron jobs, network devices and automation. All in one place.
01 / Server Monitoring
Server Monitoring
Linux metrics via the open-source agent. Default collection is 60 seconds, with custom intervals down to 5 seconds when needed.
02 / Uptime & Status
Uptime & Status
HTTPS, TCP, ICMP and DNS checks from multiple regions, with confirmation before noisy alerts reach your team.
03 / Automation & Scheduling
Automation & Scheduling
Cron job monitoring plus workflow automation for routing, retries, delays and escalations.
04 / Network
Network
SNMP monitoring for switches, routers and firewalls. Add devices explicitly and keep network health next to server health.
05 / Developer Tools
Developer Tools
API-first infrastructure monitoring. Manage monitors as code and export data when your stack needs it.

When something breaks, Fivenines confirms it, routes it and gives your team the context to act.
Know what you are installing before you install it.
The Fivenines agent is open source and uses an outbound HTTPS push model. It collects infrastructure telemetry; it does not give Fivenines a shell, an inbound port, or a remote command channel on your servers.
User-level install available · Optional modules are explicit
01
Open source
The Linux agent source is public, so engineers can inspect what runs before rolling it out.
02
Outbound only
The agent pushes metrics to Fivenines over HTTPS. Your host does not need to expose an agent port to the internet.
03
No remote control path
The dashboard cannot SSH into your server or execute arbitrary commands through the agent.
04
Explicit permissions
Base metrics work with normal local reads. Docker, Proxmox, PostgreSQL, SMART, RAID and similar modules are enabled intentionally with scoped access.

What engineers, MSPs and operators say
Fivenines has been completely reliable...
Fivenines has been completely reliable and the service continues adding features at a fast clip. My subscription just keeps gaining value, which is a great thing!

Been with the service from ground...
Been with the service from ground floor; the dev is really nice and insanely effective - more than once I've been reporting bugs and assisting with testing while things were being fixed LIVE! It's obvious that he has aspirations and he's been delivering over expectations constantly. The actual product works perfectly along the other monitoring solutions I'm using (currently Hetrixtools and Komari) and for those who are more wary of unknown code running on their prods the code is available via Git. Nothing but recommendations from me!

One of the best server monitoring tools I've used
The tool is continuously improving with dedicated developer support. They're responsive to user feedback and I've successfully deployed it as a replacement for our hosting provider's monitoring.

A note from Sébastien, founder of Fivenines
Built by engineers. Run by a small team.
I started Fivenines because every monitoring tool I tried either took too long to set up or cost more per month than the infrastructure it watched.
The agent is open-source because I do not want anything I would not audit myself running on my servers. The pricing is published because I hate request-a-quote pricing. If you have a question about your setup, email me. I read every one.
