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 Coder?
Coder hardens its core and quietly builds aibridge into a governed AI-agent gateway.
Coder's recent releases split between security maturation and AI infrastructure. A coordinated multi-advisory hardening pass—disclosed via Anthropic's Project Glasswing—tightened OIDC auth, workspace isolation, and agent command handling, with breaking changes, while parallel patches land across four supported release branches (2.29 through 2.34). Underneath, 'aibridge' is emerging as a governed AI gateway.

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.
Coder
7.5INFRA · APIS
Coder hardens its core and quietly builds aibridge into a governed AI-agent gateway.
◆ Current state
Coder's recent releases split between security maturation and AI infrastructure. A coordinated multi-advisory hardening pass—disclosed via Anthropic's Project Glasswing—tightened OIDC auth, workspace isolation, and agent command handling, with breaking changes, while parallel patches land across four supported release branches (2.29 through 2.34). Underneath, 'aibridge' is emerging as a governed AI gateway.
◆ Where it's heading
The throughline is Coder positioning its self-hosted workspaces to host AI coding agents safely: aibridge now tracks new models (Bedrock Opus 4.8, Gemini), enforces auth and request-size limits, and ships under an AI Governance license tier. Security hardening and AI-gateway buildout are advancing in tandem.
◆ Prediction
Expect aibridge to keep absorbing model support and governance controls; the breaking OIDC changes suggest more auth-surface tightening ahead as enterprise deployments consolidate onto the 2.33/2.34 lines.
