What is Cursor?
Cursor stretches agentic coding beyond the editor — cloud, mobile, automations, and an extension marketplace.
Cursor is expanding from an AI code editor into a full agentic development platform. The recent run spans new surfaces (an iOS app, always-on cloud agents), an event-driven automation layer with Slack and GitHub triggers, an extensibility marketplace consolidating plugins/skills/MCPs/subagents, enterprise org-and-team governance, SDK customization, and a faster review agent in Bugbot — much of it powered by its own Composer models. The product is racing to own the whole agentic loop, not just the moment of writing code.
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.

Cursor stretches agentic coding beyond the editor — cloud, mobile, automations, and an extension marketplace.
◆ Current state
Cursor is expanding from an AI code editor into a full agentic development platform. The recent run spans new surfaces (an iOS app, always-on cloud agents), an event-driven automation layer with Slack and GitHub triggers, an extensibility marketplace consolidating plugins/skills/MCPs/subagents, enterprise org-and-team governance, SDK customization, and a faster review agent in Bugbot — much of it powered by its own Composer models. The product is racing to own the whole agentic loop, not just the moment of writing code.
◆ Where it's heading
The direction is clear: take the agent out of the single local editor session and spread it across every surface and trigger — desktop, cloud, mobile, Slack, GitHub, CI — while adding the team/enterprise governance and marketplace ecosystem that make that sprawl manageable. Cloud and always-on agents are the throughline; automations and triggers turn Cursor reactive; canvases and Design Mode extend it past code into artifacts and UI. The bet is platform breadth backed by in-house models.
◆ Prediction
Expect continued investment in cloud and mobile agent surfaces, more automation triggers, and tighter marketplace/governance tooling for teams. Composer model improvements will likely keep feeding the review and agent features. The entries don't reveal pricing or model-roadmap specifics, so the exact next headline is unclear — but the surface-expansion pattern is strong.

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.
