Keep your services - and your team - ahead of every incident, anywhere and anytime. X-Alert watches your URLs, APIs, SSL certificates and custom metrics 24/7 and forces notifications through Do-Not-Disturb with vibration or sound so you never miss a critical alert.

🌴 Wherever you are - never miss a failure

Your phone will buzz with “502 Service Unavailable” even on holiday. Define custom alarms that pierce DND and sleep mode.

⏱ Every minute counts

Detect downtime in seconds: X-Alert pings endpoints at 5-minute (Free) or 1-minute (Premium) intervals and reports failures immediately.

📊 Custom Metric Tracking

Monitor any numeric value - response time, CPU load, business KPIs or IoT sensors—and set thresholds (“>80%”, “<10ms”, etc.).

🔔 Intelligent Alerting

Our system leverages intelligent algorithms to detect fail-streaks and consecutive-failure patterns to cut down on noise.

👥 Team Notifications & Controls

Invite colleagues, mute per-alert or project-wide.

📈 Dashboard & History

Explore logs, trends and graphs for every check - perfect for fast root-cause analysis.

🔗 Webhooks & REST API

Automate monitor creation, threshold updates and fetch historical data through our open API.
