Fivenines is a cloud platform combining server, network, uptime, and cron monitoring. Its open-source agent monitors Linux and Windows servers every 60 seconds by default, with custom intervals down to five seconds. Uptime checks cover HTTPS, TCP, ICMP, and DNS from multiple regions, tracking response time, availability, and SSL expiry. Cron monitoring alerts when scheduled jobs miss a run or finish late. Workflows can route alerts and apply retries, delays, and escalations. Depending on plan, notifications can use email, Slack, Microsoft Teams, Telegram, Discord, Pushover, PagerDuty, or webhooks. Developer tools include a REST API, Terraform provider, and MCP server for Claude or other MCP clients. The agent sends telemetry outbound over HTTPS and has no remote shell, inbound agent port, or arbitrary command channel. Fivenines is hosted in the European Union and describes its handling as GDPR-aware. A 14-day trial needs no credit card; paid plans start at 15.00 EUR per month.
