Nock Nock

Nock Nock is an open-source Android application for checking whether websites or web servers are available and responding successfully. It automatically sends requests to selected sites at an interval chosen by the user. The app is intended for people who maintain, develop, or otherwise need to monitor web services.

Its basic check uses an HTTP GET request and examines the response code returned by the server. Nock Nock can also perform custom validation by looking for a specified term in the response. For more flexible checks, it can execute a custom block of JavaScript.

When a check indicates that something is wrong, Nock Nock sends a notification to the user. This provides a direct way to learn about an unsuccessful response without repeatedly checking the site manually. The combination of scheduled requests, response-code checks, content validation, and notifications covers several straightforward availability-monitoring needs.

Nock Nock is listed in MirrorNest’s Development category because it supports the checking of websites and web servers. Its Android platform makes the monitoring tool available on compatible Android devices, while its open-source license identifies how the software is provided. MirrorNest mirrors the official build on its own storage and scans it for malware before publishing it.
