Boxwatch Server Monitoring

BoxWatch is server monitoring that does the job of four tools at once: metrics, cron heartbeats, uptime checks, and process monitoring. One agent, one dashboard, one bill. Most teams stitch together Datadog (or similar) for metrics, Healthchecks.io for cron, UptimeRobot for HTTP checks, and a separate supervisor for processes. BoxWatch replaces all of that. Metrics: CPU, memory, disk, network, load, and uptime, collected by a small open-source bash agent installed with one curl command. Trend charts, side-by-side comparison views, and disk-full prediction that warns you days before a volume actually fills. Cron heartbeats: ping a URL when a job finishes, get alerted when the ping is late or missing. Four alert types with transition-based dedup so you never get spammed. Uptime checks: HTTP, TCP, and TLS-expiry probes executed by your own deployed BoxWatch agents. Multi-region as a side effect of your fleet, and capable of monitoring internal-network endpoints that hosted competitors cannot reach. Process monitoring: watch named processes on every server, get alerted when one disappears or restarts. Alerts via email, Slack, Discord, or any webhook (PagerDuty, Zapier, n8n, custom scripts). Smart cooldowns, recovery notifications, and maintenance windows that suppress noise during planned downtime. Also included: branded public status pages with incident management, uptime SLA tracking (24h, 7d, 30d, 90d), TV dashboard mode for wall displays, weekly digest emails, monthly detailed reports, 2FA, scoped API keys, and Stripe self-service billing. Free tier: 2 servers, no credit card, forever. Pro $13/mo for 7 servers, Team $29/mo for 25, Scale $79/mo for 100. No per-metric or per-check fees, no surprise bills. One curl command, sixty seconds, monitoring. The agent is open source so you can read every line first. Use G2 as a coupon to get an extra 2 servers for free for life on any plan
