Uptime-monitor

Monitor sites, APIs, WebSockets, DNS, ports, and SSL certificates from your own device.

Private uptime monitoring for websites, APIs, WebSockets, TCP ports, DNS records, and SSL certificates. Run checks from your Mac, iPhone, or iPad, with local history, performance charts, failure notifications, and webhook alerts.

Create checks for websites, HTTP APIs, WebSocket endpoints, TCP ports, DNS hostnames, and SSL certificates. Set the interval that makes sense for each kind of check, choose request timeouts and slow-response thresholds, and see whether each service is healthy, slow, unreachable, or close to certificate expiry.

Fine-tune HTTP checks with raw, JSON, or form-encoded bodies, expected status matching, and response content assertions. When you need to troubleshoot, open diagnostics for response headers and DNS lookups, then export logs as CSV or JSON for sharing or archiving.

When a service starts failing, choose how many consecutive failures open an incident. Uptime Monitor sends one local notification per incident and retries its failure webhook until one delivery succeeds, can notify you when the service recovers, and lets you snooze alerts per monitor during maintenance while checks and logs keep running.

Every check is saved to local history. Review the full log with status, check type, date, and target filters, or open an item's detail page for current status, recent history, performance chart, uptime stats, configuration, and item-specific logs.

Organize larger monitor lists with multiple tags per monitor and filter by tag. A monitoring confidence indicator shows whether scheduled checks are active, delayed, or paused, together with the latest monitoring cycle and effective interval.

For deeper debugging, copy ready-to-run terminal commands for each check type: cURL for HTTP, websocat for WebSocket, nc for TCP, dig for DNS, and openssl for SSL.

Uptime Monitor runs client-side. Checks run when your device and the app are able to perform them; your checks and logs stay on your device unless you configure your own webhook endpoint.
