I have a tangentially related tip or suggestion of which many appear to be unaware: most (all?) cellphone service providers (at least in the US) let you send and receive emails over text message. For example, with Project Fi you'd use $NUMBER@msg.fi.google.com [0]. You can use this as a super simple alert or notification system for scripting and small self-hosted apps without having to setup any additional services or tools. However, it's important to keep in mind that both email and text messaging are unencrypted by default, so you should be careful with what you send. Let's consider a situation in which this might be useful: You have a 15 to 30 minute task running, such as downloading a large file (e.g. Linux ISOs) from a remote server or compiling a small C++ project. Instead of sitting around waiting you could go outside for a short walk in order to get a bit of exercise and sunlight, which helps you get to the recommended minimum of 10k daily steps. Once the task is finished you receive a text message which prompts you to head back inside. If you just want to send yourself notifications then you can actually get pretty far only using email and text messaging. However, I'm aware that OpenPush solves a few different problems, and I love that we're finally getting an open-source self-hosted alternative to GCM.
