Monitoring alerts, wherever you work
Quick answer
Where can Lemwatch send website monitoring alerts?
Lemwatch sends downtime, SSL, performance and SEO alerts to Slack, Discord, Telegram, Microsoft Teams, Google Chat, PagerDuty, email, RSS or any webhook URL.
- Chat channels are unlimited on every plan, including the free one.
- PagerDuty raises and auto-resolves incidents through the Events API v2.
- A REST API and a hosted MCP server expose the same data to code and AI assistants.
Slack alerts
Lemwatch posts uptime, SSL, performance and SEO alerts straight into any Slack channel using an incoming webhook. It is included on every plan, including the free one, with no message limit.
Discord alerts
Lemwatch sends downtime and site-health alerts to a Discord channel through a channel webhook, colour-coded by severity. It works on every plan, including free, with no message cap.
Telegram alerts
Lemwatch can message you on Telegram the moment a site goes down, using your own bot. You supply a bot token and a chat ID; delivery is unlimited on every plan, including free.
Microsoft Teams alerts
Lemwatch posts site-health alerts into a Microsoft Teams channel through an incoming webhook. It is available on every plan, including free, with no per-message charge.
Google Chat alerts
Lemwatch delivers downtime and recovery alerts into a Google Chat space using a space webhook. It is unlimited on every plan, including free.
PagerDuty alerts
Lemwatch raises PagerDuty incidents through the Events API v2 and resolves them automatically when the site recovers, so on-call rotation, escalation and acknowledgement all stay in PagerDuty.
Custom webhooks alerts
Lemwatch can POST a JSON payload to any URL you control when a site changes state, which is how you connect it to Zapier, Make, n8n, an internal service or a tool with no native integration.
