Uptime-monitor

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 something fails, Uptime Monitor can notify you locally and send a per-item failure webhook to your own endpoint. Webhooks support GET or POST, custom headers, optional POST bodies, and a built-in test action so you can confirm the integration before relying on it. 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. 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.
