# relay19 > relay19 is an uptime and server monitoring service built and hosted in the EU. It runs HTTP, TLS, SMTP, DNS, TCP and heartbeat checks against your endpoints, and a one-line Linux agent reports CPU, memory, disk and Docker containers. Alerts arrive by email, Slack, Discord, Microsoft Teams, Telegram, ntfy, PagerDuty and signed webhooks, and teams get roles plus an audit trail. Key facts: - The app lives at https://p.relay19.com (sign up, sign in, and the agent install endpoint). - Free plan: 10 monitors, 5 minute checks, 1 probe location, 1 server agent, 1 seat, 7 days of history. Free forever, no card. - Paid plans are self-serve and priced per month excluding VAT: Starter at 9 EUR (50 monitors, 30s checks, 3 probe locations, 5 server agents, 5 seats, 90 days of history); Team at 29 EUR (100 monitors, 30s checks, all probe locations, 10 server agents, 10 seats, 1 year of history); Scale at 59 EUR (300 monitors, 15s checks, all probe locations, 30 server agents, unlimited seats, 1 year of history).
