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 Render?
Render is rebuilding itself around agents and secretless auth.
Render is a PaaS whose recent releases have turned its MCP server and OIDC auth into first-class surfaces. Coding agents can now trigger deploys and authenticate over OAuth, and hosted services get short-lived credentials to AWS and, now, Anthropic and OpenAI. The Postgres and Key Value work — pooling, CLI management — continues in parallel as table-stakes infrastructure.

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.

Render is rebuilding itself around agents and secretless auth.
◆ Current state
Render is a PaaS whose recent releases have turned its MCP server and OIDC auth into first-class surfaces. Coding agents can now trigger deploys and authenticate over OAuth, and hosted services get short-lived credentials to AWS and, now, Anthropic and OpenAI. The Postgres and Key Value work — pooling, CLI management — continues in parallel as table-stakes infrastructure.
◆ Where it's heading
The direction is a deploy platform built for both humans and agents, where static secrets give way to managed OIDC. Nearly every release this month either widened the MCP tool surface or extended secretless auth to another provider.
◆ Prediction
Expect more MCP tools beyond trigger_deploy and OIDC coverage for additional providers; the AWS-to-Anthropic/OpenAI pattern suggests any external service a hosted app calls is a candidate for secretless auth.
