What is Port?
Port is turning its developer catalog into an AI- and MCP-native control plane.
Port has spent the last two quarters converting its internal developer platform into an AI-and-agent surface. Nearly every monthly release now leads with Port AI: an MCP gateway, bring-your-own-LLM routing, agent governance, and now an opening plugin ecosystem. The underlying catalog, scorecards, and RBAC work continues, but it increasingly serves as context the AI layer reasons over rather than the headline itself.
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.

Port is turning its developer catalog into an AI- and MCP-native control plane.
◆ Current state
Port has spent the last two quarters converting its internal developer platform into an AI-and-agent surface. Nearly every monthly release now leads with Port AI: an MCP gateway, bring-your-own-LLM routing, agent governance, and now an opening plugin ecosystem. The underlying catalog, scorecards, and RBAC work continues, but it increasingly serves as context the AI layer reasons over rather than the headline itself.
◆ Where it's heading
The direction is a platform you build on and talk to, not just configure. MCP connectors, custom widgets, a public plugins repo, and structured AI outputs all point to Port positioning itself as the governed entry point for agentic engineering workflows. Governance is keeping pace deliberately — permission simulators, audit logs, and per-trigger access controls ship alongside each AI expansion, which signals an enterprise buyer.
◆ Prediction
Expect the plugins repo and custom widgets to converge into a first-class marketplace, and the Claude Code/Copilot usage tracking to grow into broader AI-spend and agent-activity analytics across the catalog.

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.
