10 channels · zero noise
Ten channels. One alert. Every channel delivers the same rich context: monitor name, status, response time, screenshots, and direct links to investigate.
Free on every plan. One-click enable. Works on desktop and mobile, even when the dashboard tab is closed. No additional setup.
Every alert is available via our REST API. Create monitors, manage channels, query incidents, and build custom dashboards, all programmatically.
