What is Ably?
Ably's AI Transport SDK graduates to Temporal orchestration and Vercel AI SDK v7 in the same release.
Ably is running two parallel development tracks: hardening LiveObjects (now stable in the Cocoa SDK with a path-based API) for collaborative and AI-state use cases, and expanding the AI Transport SDK to support durable agent orchestration via Temporal and compatibility with Vercel AI SDK v7. The JS SDK also resolved a long-standing WebSocket fallback gap for proxy-blocked networks.
What is Porter?
Porter tightens its security layer with short-lived cloud credentials and zero-trust workload access.
Porter is a Kubernetes-based PaaS targeting engineering teams that want AWS/GCP infrastructure without managing raw k8s. Over the past year it has added GPU job support, temporal-based autoscaling, multiple node groups, and overhauled both application creation and datastore management flows. The most recent release focuses squarely on access control: short-lived cloud credentials and secure cloud access for workloads indicate a move toward zero-trust IAM patterns at the infrastructure level.

Ably
6.3INFRA · APIS
Ably's AI Transport SDK graduates to Temporal orchestration and Vercel AI SDK v7 in the same release.
◆ Current state
Ably is running two parallel development tracks: hardening LiveObjects (now stable in the Cocoa SDK with a path-based API) for collaborative and AI-state use cases, and expanding the AI Transport SDK to support durable agent orchestration via Temporal and compatibility with Vercel AI SDK v7. The JS SDK also resolved a long-standing WebSocket fallback gap for proxy-blocked networks.
◆ Where it's heading
The AI Transport SDK is emerging as Ably's primary growth vector — each release adds a new agent framework integration (Temporal, Vercel AI, OpenAI Responses API) or a new agent control mechanism (mid-run steering, human approvals). LiveObjects is stable now and will likely see slower iteration as it shifts to a reliability rather than feature phase.
◆ Prediction
The next AI Transport release will probably add support for another major agent framework (likely LangChain or CrewAI) as Ably builds toward covering every major orchestration layer for real-time agent streaming.
Porter
0.0INFRA · APIS
Porter tightens its security layer with short-lived cloud credentials and zero-trust workload access.
◆ Current state
Porter is a Kubernetes-based PaaS targeting engineering teams that want AWS/GCP infrastructure without managing raw k8s. Over the past year it has added GPU job support, temporal-based autoscaling, multiple node groups, and overhauled both application creation and datastore management flows. The most recent release focuses squarely on access control: short-lived cloud credentials and secure cloud access for workloads indicate a move toward zero-trust IAM patterns at the infrastructure level.
◆ Where it's heading
Porter is building a security and compliance layer on top of its deployment primitives — audit logs appear twice across these entries, SOC 2 controls via Drata, short-lived credentials, and workload identity. In parallel, AI-adjacent features have appeared at each release cycle: DeepSeek-R1 model deployment, a Helicone observability add-on, GPU time-slicing, and full GPU Jobs. The two tracks — security hardening and AI infrastructure — are converging toward a production-ready positioning for AI workloads.
◆ Prediction
The next release will likely push deeper on IAM: workload-level RBAC and service account policies are the logical follow-on to short-lived credentials. Expanded GPU options for training (not just inference) jobs are probable given the incremental progression from time-slicing to full GPU Jobs.
