Dagster and Prefect announced that Prefect is acquiring Dagster Labs, with Dagster open source and Dagster+ remaining supported under existing names and licences, the companies said on 13 July 2026.
Data orchestration vendors are consolidating as AI pipelines raise the bar on asset-aware scheduling and reliability. Buyers still need migration clarity, licence continuity and dual-product support windows.
Dagster remains the directory brand face; Prefect is the acquiring parent and is not added as a separate directory slug this wave. The combined company was expected to operate under the Prefect name from August 2026 with no customer migration required at announcement.
Data platform owners should demand support-continuity commitments — before treating any acquisition as a completed orchestration strategy.
