* Completely free, for any number of users. Great if you want i.e. internal notifications in a small, underfunded organization, or even 2FA codes. This might not be the best option security-wise, but has a lot of advantages if you want to prevent intentional account sharing, for example.
* Syncs across all platforms, including your own (the Telegram client API is available free of charge, although it is not easy to use)
* Extremely simple API, to the point of being able to play with it in a browser or via CURL. This is in contrast to the client API, which doesn't even use HTTP and runs on top of custom crypto protocols.
* All the features you might expect from a messaging service, including file attachments, receiving user input (for quickly dealing with alerts from your phone), muting specific notification bots, including for specific amounts of time, full message history etc.
I was tired of setting up channels and playing around with the telegram/slack API for every new project I started so I just thought I build my own version of it and made it super simple with just one AJAX call.
I have some plans for it and there'll be more features coming in the future.
Example: sleep 100; push "done!"
Where push is my wrapper around curl to their API with the proper keys.
