What is Ably?

Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.

Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.

What is DatoCMS?

Headless CMS spends April hardening the developer surface and adding antivirus to the media pipeline.

DatoCMS is a headless CMS. April brought a security upgrade (automatic antivirus scanning across every Media Area upload, with CDN purge on detection), three coordinated CLI/DX improvements (unscoped npm package, OAuth-based project linking, plugin scaffolds in Astro and Next.js starters), and a Developer Plan API limit bump. Earlier in the window: in-CMS video editing alongside the existing image editor, permissions for Asset Collections, and pre-filtered linked record menus.

Ably vs DatoCMS: editorial side-by-side

6.3

Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.

◆ Current state

Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.

◆ Where it's heading

Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.

◆ Prediction

Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.

Headless CMS spends April hardening the developer surface and adding antivirus to the media pipeline.

◆ Current state

DatoCMS is a headless CMS. April brought a security upgrade (automatic antivirus scanning across every Media Area upload, with CDN purge on detection), three coordinated CLI/DX improvements (unscoped npm package, OAuth-based project linking, plugin scaffolds in Astro and Next.js starters), and a Developer Plan API limit bump. Earlier in the window: in-CMS video editing alongside the existing image editor, permissions for Asset Collections, and pre-filtered linked record menus.

◆ Where it's heading

Two parallel threads — cleaner developer onboarding (OAuth CLI replacing copy-paste tokens, plugin scaffolds shipped with starters, npx that just works) and treating the Media Area as a more hardened surface (in-CMS editing, asset permissions, antivirus). The CLI work reads as DatoCMS investing in becoming the type of CMS a developer can integrate without three copy-paste rituals.

◆ Prediction

Expect the OAuth CLI to become the only documented path within a few releases, more antivirus-style trust features (likely SOC-2 attested workflows or content-policy scanning), and starter-kit ecosystem investment that widens framework support beyond Astro and Next.js.
