Overview
Ably is a realtime data delivery platform offering pub/sub messaging, presence, and message persistence through WebSocket edge infrastructure spanning 11+ regions and 700+ points of presence. It supports multiple protocols and client SDKs for building chat, live data, and collaborative features. Ably prices plans by concurrent connections, channels, and message throughput, plus usage-based charges for messages, connection minutes, and data transfer.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Ably.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for Ably, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
