fivenines.io combines server, uptime, cron, and network monitoring in one dashboard, with a free plan and paid tiers starting at €9/month.
fivenines.io was founded in 2024 by Sébastien Puyet, a software engineer based in Montpellier, France, who built the platform after finding existing monitoring tools either too slow to set up or too expensive relative to the infrastructure they were monitoring. It combines server metrics, uptime checks, cron job monitoring, and network device tracking into a single dashboard rather than requiring separate tools for each.
The company positions itself as a modern, faster-to-deploy alternative to legacy tools like Nagios, emphasizing a roughly two-minute setup per server: create an account, install the open-source monitoring agent, and see metrics in the dashboard within about 60 seconds.
The monitoring agent is open source and published on GitHub, so customers can audit exactly what it collects and how, rather than trusting a closed-source binary with remote execution capability. Data is pushed over HTTPS, so no inbound firewall ports need to be opened on monitored servers.
Beyond core server and uptime monitoring, the platform supports Docker, Proxmox, GPU, and database monitoring modules, multi-region uptime confirmation to reduce false alerts, white-label status pages, a REST API, a Terraform provider for infrastructure-as-code workflows, and SNMP-based network device monitoring included by default rather than as a paid add-on.
fivenines.io offers a free tier for a small number of servers monitored at reduced check frequency, alongside three core paid plans: Starter at €9 per month for 15 monitors and 3 team members, Pro at €27 per month for 50 monitors and 10 team members, and Business at €49 per month for 100 monitors and 25 team members, each with increasing data retention windows.
All monitor types, whether servers, uptime checks, cron jobs, or network devices, count equally toward the plan's monitor limit. An Enterprise tier offers custom pricing for 300 or more monitors with dedicated support, and every paid plan includes a 14-day free trial with no credit card required.
