What is Ably?
Ably is bending its realtime stack toward AI-agent transport
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
What is Auth0?
Auth0 doubles down on enterprise provisioning and machine identity for the agent era
Auth0 is expanding well beyond login into the full enterprise identity lifecycle. Recent releases center on SCIM provisioning in both directions, refresh-token lifecycle control, and machine-to-machine access scoped for AI agents and partner backends. Alongside the capability work, the Dashboard is getting an information-architecture and search overhaul.

Ably is bending its realtime stack toward AI-agent transport
◆ Current state
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
◆ Where it's heading
The AI Transport SDK is where Ably is placing its directional bet: session/run models, branching conversations, human-in-the-loop handoff, and now external data hydration all point at owning the realtime layer for agent applications. In parallel the mainline JS client is formalizing React-first ergonomics and deprecating its v1 callback API.
◆ Prediction
Expect the AI Transport SDK to hold its rapid cadence toward a 1.0, and the newly released Dart SDK to follow the same early-adoption-to-stable path.

Auth0 doubles down on enterprise provisioning and machine identity for the agent era
◆ Current state
Auth0 is expanding well beyond login into the full enterprise identity lifecycle. Recent releases center on SCIM provisioning in both directions, refresh-token lifecycle control, and machine-to-machine access scoped for AI agents and partner backends. Alongside the capability work, the Dashboard is getting an information-architecture and search overhaul.
◆ Where it's heading
The clear arc is B2B provisioning depth: inbound SCIM groups reached GA, Google Workspace group sync opened up, and now outbound SCIM lets Auth0 push user changes downstream without custom infrastructure, making Auth0 a bidirectional provisioning hub rather than only an IdP. In parallel, refresh-token metadata and bulk revocation give operators finer session control, and M2M access for third-party apps positions Auth0 for agent-to-API authorization.
◆ Prediction
Expect the Early Access provisioning and refresh-token endpoints to move toward GA, and the Dashboard IA refresh to exit beta as the default experience.
