hubValidations vs Windmill: at a glance
What is hubValidations?
Submission validation for forecast hubs, rebuilt around which file each check belongs to.
hubValidations checks submissions to collaborative forecasting hubs — file names, schemas, task-id combinations, sample structure — and runs inside pull-request automation on the hub repository. The package crossed a 2.0.0 boundary that reorganised how multi-file validation results are represented, and the releases since have been narrow additions to sample checking and fixes to the GitHub API integration. Its surface is large, with individual named checks as the unit of extension.
What is Windmill?
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.

hubValidations

Submission validation for forecast hubs, rebuilt around which file each check belongs to.
◆ Current state
hubValidations checks submissions to collaborative forecasting hubs — file names, schemas, task-id combinations, sample structure — and runs inside pull-request automation on the hub repository. The package crossed a 2.0.0 boundary that reorganised how multi-file validation results are represented, and the releases since have been narrow additions to sample checking and fixes to the GitHub API integration. Its surface is large, with individual named checks as the unit of extension.
◆ Where it's heading
The architectural work is done and the package has returned to incremental check-writing, particularly around samples, where model tasks can carry independent configurations. A parallel thread makes validation output more communicative: informational warnings that do not fail a submission, prominent display of config-file changes, and clearer errors where a cryptic dplyr failure used to surface. The GitHub integration keeps producing small defects, being the one part not exercised by ordinary local use.
◆ Prediction
Expect further sample-related checks and continued refinement of what validation output communicates to hub maintainers, rather than another architectural change so soon after 2.0.0.
Windmill
8.8INFRA · APIS
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
◆ Current state
In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.
◆ Where it's heading
The community edition is being loaded up with exactly what a data team needs to run a real trial: warehouse connectors, an unmodified dbt project, storage quota instead of an upload cap. Enterprise is being repositioned around scale and governance rather than feature access. The AI sessions track is developing on its own clock, moving from chat toward durable, versioned work products that survive a session.
◆ Prediction
Expect AI session artifacts to gain server-side persistence and sharing, since they are still stored in the browser and tied to the session. On the data side, the dbt runtime is likely to grow scheduling and lineage integration with the pipelines alpha rather than staying a standalone script language.
