Satellite is a large scale web broadcasting service. It lets your send JSON messages to millions of online subscribers in near-real-time.
While there are a lot of websocket and server side event based messaging services on the market today, Satellite stands out because of it's emphasis on horizontal scalability: the strong correlation between cost and the number of simultaneous connections has been removed. This means that you can scale to sending messages to millions of users while paying only based on the number of deliveries.
Satellite will have a simple pricing scheme of USD $1 per 1,000,000 messages delivered or received. No startup, setup, max-connection or any other costs.
