Ably: Pricing, Features & Alternatives
Ably is Pusher's more rigorous competitor: the pitch is not just realtime but guaranteed realtime, with message ordering, exactly-once delivery, connection state recovery after a drop, and a 99.999% uptime SLA. Standard starts at $29 plus usage at $2.50 per million messages. For a chat product or a collaborative editor where a dropped message is a bug report, the guarantees are the reason to pay.
