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 Airbyte?

Airbyte 2.0 made the pipeline run both ways: data activation turns the warehouse into a source.

The release line runs from 1.1 through 2.0, each version bundling platform-wide changes: log filtering and OpenShift support, file transfers, schema refresh controls, declarative OAuth in the connector builder, connection health dashboards, and pagination for workspaces with thousands of connections. Version 2.0 in October 2025 is the pivot, taking both faster sync speed and data activation to general availability. The tracked feed has been quiet since, with the only 2026 row being a mis-scraped GitHub profile page.

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.

Airbyte 2.0 made the pipeline run both ways: data activation turns the warehouse into a source.

◆ Current state

The release line runs from 1.1 through 2.0, each version bundling platform-wide changes: log filtering and OpenShift support, file transfers, schema refresh controls, declarative OAuth in the connector builder, connection health dashboards, and pagination for workspaces with thousands of connections. Version 2.0 in October 2025 is the pivot, taking both faster sync speed and data activation to general availability. The tracked feed has been quiet since, with the only 2026 row being a mis-scraped GitHub profile page.

◆ Where it's heading

Airbyte spent the 1.x line making ingestion dependable at scale — performance, observability, deployment targets, connector authoring — and then used 2.0 to run the pipeline in reverse, delivering modeled warehouse data into CRMs, marketing platforms, and support tools. That puts it against reverse-ETL vendors rather than only extract-and-load competitors, using the same connector catalog for both directions. The 1.7 work on moving files alongside records points at the other demand driver: unstructured data for retrieval systems.

◆ Prediction

Expect data activation to widen its destination catalog on the operational side, since the value of reverse ETL scales with how many business tools it can write into.
