Continuous uptime, API health & latency monitoring
Verify real availability for HTTP endpoints, APIs, and network ports. Get notified immediately via Telegram, Email, or Slack when downtime strikes.
Fast outage detection without false alarms
Isolated network blips should not trigger critical alerts in the middle of the night. Deltum confirms errors from an independent location before dispatching an alert, ensuring you only get notified when downtime is real.
Continuous Availability Probes
Keep your services monitored continuously, with high-frequency intervals up to 1 minute on paid plans.
HTTP & JSON Payload Validation
Go beyond basic status codes. Validate response headers, TTFB latency, and expected JSON body contents.
TCP Port & Database Monitoring
Check connectivity and response times for direct backend ports (PostgreSQL, MySQL, Redis, SMTP).
How it works in 3 simple steps
Configure your endpoints
Add your target URLs, custom auth headers, and expected status codes or body content.
Automated health probes
Our distributed nodes check your endpoints regularly and record detailed response time telemetry.
Actionable alerts with error context
If an endpoint fails, receive instant notifications via Telegram, Email, Slack, or Webhook with clear error details.
