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.
What is Knock?
Notification infrastructure grows a memory: workflows can now wait on the real world.
Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.

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.

Notification infrastructure grows a memory: workflows can now wait on the real world.
◆ Current state
Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.
◆ Where it's heading
The developer-workflow half of the product is being treated like a codebase: branches that rebase onto main, tests that run in sandbox without delivering, tags and saved views for navigating a growing workspace. The engine half is moving in a different direction — toward workflows that hold state over time. A wait-for-event step, combined with the Clay data source triggering messaging as rows finish enriching, describes journeys rather than notifications. The analytics work is arriving twice over: raw events into the warehouse for teams with their own stack, and natural-language questions to the Knock agent for teams without one.
◆ Prediction
Wait-for-event is the primitive that makes journey-shaped use cases possible, so expect the next releases to address what it exposes — timeouts, observability into workflows sitting paused, and limits on how long one can wait before it becomes a support problem.
