Apache Airflow vs Windmill
A side-by-side editorial comparison of Apache Airflow and Windmill — release velocity, themes, recent moves, and the top alternatives to consider.
Apache Airflow vs Windmill: at a glance
What is Apache Airflow?
Airflow's Go, Java and TypeScript SDKs all reach 1.0 on the same day.
On November 13 Apache Airflow released stable 1.0.0 SDKs for Java, TypeScript and Go within an hour. The Java SDK authors Dags natively, with dependencies, task groups, branching, Dag triggers and the Variable and task state APIs, serialized to the same format as Python Dags. The Go and TypeScript 1.0 releases are mostly last fixes after their betas. The Amazon provider 9.40.0 also went final.
What is Windmill?
Windmill keeps turning AI clients into the place you build and run its workflows.
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
Apache Airflow vs Windmill: editorial side-by-side
Apache Airflow
7.5INFRA · APIS
Airflow's Go, Java and TypeScript SDKs all reach 1.0 on the same day.
◆ Current state
On November 13 Apache Airflow released stable 1.0.0 SDKs for Java, TypeScript and Go within an hour. The Java SDK authors Dags natively, with dependencies, task groups, branching, Dag triggers and the Variable and task state APIs, serialized to the same format as Python Dags. The Go and TypeScript 1.0 releases are mostly last fixes after their betas. The Amazon provider 9.40.0 also went final.
◆ Where it's heading
Airflow 3.4 made non-Python Dags possible as an experiment; a week later the language SDKs are declared stable. The project is turning its scheduler into a runtime that teams in Java, Go and TypeScript shops can adopt without writing Python. Provider releases keep their usual batched cadence underneath.
◆ Prediction
Expect the experimental Dag Importer and Task Loops from 3.4 to move toward stable in a 3.5 release, and SDK patch releases as first production users report issues.
Windmill
5.0INFRA · APIS
Windmill keeps turning AI clients into the place you build and run its workflows.
◆ Current state
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
◆ Where it's heading
The direction is clear: Windmill wants to be the execution backend that AI clients drive, not just a UI people click through. MCP moved from a tool list to a build-and-deploy surface, then to interactive cards inside the chat. The roles and seat changes suggest it is preparing to price the wider set of people who can now build through AI.
◆ Prediction
Expect more of the deploy and review lifecycle to surface inside MCP clients, and finer-grained role controls over which MCP tools each role gets.
