It's All Good is a simple service monitoring framework to make it easy to monitor various services on a server. Its API is dead simple, and a handful of modules are already available for common things like disk usage, checking that SMTP is running, SSL certs are valid, or a page's contents. It can easily be used with a service like Pingdom so that you can monitor your servers' health with only 1 alert (which you can get for free). It's small, compact, fast, and loads nicely on most mobile devices including your iPhone or Android device.
h2H Messenger is a secure messenger client that uses PHP OpenSSL functions, mcrypt, and PHPSecLib to encrypt messages at-rest using RSA keys. The user only creates an account and the application handles the public key generation, key management, key exchange, and encryption and decryption of messages. There are no algorithms or key sizes to choose. It uses strong standards (AES 256, 4096 bit RSA Keys, SHA1, SHA512, etc.) in the background, and requires two-factor authentication using a code sent via SMS or using Asterisk.
URL Router is a PHP class that can match URLs with routes for controllers and actions. It takes the definition of one or more routes with string expressions that define patterns to match given URLs. It supports a special route pattern syntax that allows defining how to extract the name of the controller and action from the URL. The class returns an array with the details of the matched route.
