What is Ably?
Ably is building a realtime transport purpose-built for AI agents, alongside its LiveObjects push
Ably's changelog splits into two active tracks. The established Pub/Sub SDKs keep gaining LiveObjects support (a new React useObject hook, Java path-based API) and platform reach (React Native push). In parallel, the AI Transport SDK is advancing quickly through 0.x releases, adding agent-specific primitives: mid-run steering, durable execution via Steps, and external data hydration.
What is Pressable?
Pressable is turning managed WordPress into a bulk-ops and MCP control surface
Pressable is a managed WordPress host that has spent recent weeks converting nearly every dashboard action into a bulk operation and a matching API/MCP endpoint. The changelog reads as an agency-ops grind: bulk CDN purges, bulk basic-auth, bulk APM toggles, alongside a parallel push to expose the same controls through its MCP server. This is platform plumbing aimed squarely at customers managing many sites at once.

Ably is building a realtime transport purpose-built for AI agents, alongside its LiveObjects push
◆ Current state
Ably's changelog splits into two active tracks. The established Pub/Sub SDKs keep gaining LiveObjects support (a new React useObject hook, Java path-based API) and platform reach (React Native push). In parallel, the AI Transport SDK is advancing quickly through 0.x releases, adding agent-specific primitives: mid-run steering, durable execution via Steps, and external data hydration.
◆ Where it's heading
The strategic bet is AI Transport, a realtime layer designed for streaming, resumable, steerable agent runs rather than generic pub/sub. Each 0.x release fills in a capability agent apps need (survive restarts, steer mid-run, seed from an external store), while LiveObjects matures the state-sync side. Ably is repositioning realtime infrastructure for the agent era.
◆ Prediction
Expect the AI Transport SDK to keep hardening toward a stable 1.0 with more agent-run primitives, and LiveObjects to spread across the remaining language SDKs.

Pressable is turning managed WordPress into a bulk-ops and MCP control surface
◆ Current state
Pressable is a managed WordPress host that has spent recent weeks converting nearly every dashboard action into a bulk operation and a matching API/MCP endpoint. The changelog reads as an agency-ops grind: bulk CDN purges, bulk basic-auth, bulk APM toggles, alongside a parallel push to expose the same controls through its MCP server. This is platform plumbing aimed squarely at customers managing many sites at once.
◆ Where it's heading
The direction is programmatic, multi-site management: every human dashboard control is getting an API and MCP twin so fleets of sites, and increasingly AI agents, can be driven without clicking. Recent MCP token revocation and site-creator attributes show the MCP surface maturing from a feature into a governed, auditable control plane.
◆ Prediction
Expect continued one-to-one bulk/API/MCP coverage of the remaining single-site controls, with more governance around the MCP layer as it becomes the primary automation entry point.
