Echobell turns webhooks and emails into alerts you can't miss on iPhone and Apple Watch: a push notification, a Time-Sensitive alert that breaks through Focus, or a phone call that rings through Silent Mode. Give any tool your channel's webhook URL or email address. When a server goes down, a build fails, a price crosses your line or your AI agent needs you, your phone knows within seconds. THREE ALERT LEVELS • Push: a standard notification for routine events • Time-Sensitive: breaks through Focus so important alerts get seen • Phone call: rings like an incoming call, on iPhone and Apple Watch, and reads the alert aloud CONNECT ANYTHING • Every channel gets its own webhook URL and email address • Works with anything that can send an HTTP request or an email: Grafana, Prometheus Alertmanager, Uptime Kuma, UptimeRobot, Zabbix, TradingView, n8n, Zapier, Make, IFTTT, Home Assistant, GitHub Actions, cron jobs and your own scripts • AI agents: connect Claude Code, Codex, Cursor or any MCP client to Echobell's MCP server so it can notify you, or call you, when work finishes or it needs your input ONLY THE ALERTS THAT MATTER • Templates turn raw JSON into a clear title and message • Conditions filter the noise: alert only when status is "error", when a price passes 50,000, or within the hours you set • Links in each alert open the right dashboard, chart or runbook BUILT FOR TEAMS AND ON-CALL • Share a channel with one link • Every subscriber picks their own level: a call for whoever is on call, a push for everyone else PRIVATE BY DESIGN Notification content and history stay on your device.
