Windmill: Scripts to Workflows Without the Glue Code
Open-source platform that turns Python, TypeScript, or SQL into production webhooks, scheduled jobs, and internal UIs. 13x faster than Airflow for complex workflows.
windmill-labs/windmill ↗Windmill is a self-hosted platform that takes your scripts and auto-wires them into usable infrastructure. Write a Python function to sync customer data, a SQL query to generate reports, or a TypeScript job to scrape—Windmill turns each into a webhook you can call, a schedule you can trigger, or a form-based UI your team can use without touching code.
It's positioned between Retool (UI builder, closed-source) and Temporal (workflow engine, enterprise pricing). The speed matters: Windmill's execution layer is 13x faster than Airflow on complex workflows, which saves real time and compute if you're orchestrating dozens of jobs daily. For solopreneurs shipping internal tools or teams building infrastructure automation, this cuts weeks of wiring boilerplate.

Windmill: Turn scripts into production workflows (13x faster than Airflow)
Open-source platform that auto-wires Python, TypeScript, and SQL into webhooks, scheduled jobs, and UIs. No boilerplate. Self-hosted. 13x faster execution than Airflow. Worth a test if you're building internal infra or automation tooling.
Windmill does what Retool and Airflow do, but in one place and without the boilerplate tax. Write a script. Get a webhook, a schedule, and a UI. Open-source, self-hosted, 13x faster than Airflow. For teams shipping internal tooling and infra automation, it's the kind of unglamorous win that saves weeks.
We shipped Windmill to the Vaib Report because it solves a real friction point: teams spend weeks wiring scripts into production infrastructure. Windmill compresses that into minutes. Python function becomes a webhook. SQL query becomes a scheduled report. TypeScript task becomes an API. Open-source, self-hosted, measurably faster than existing alternatives. Worth evaluating if you're building internal tooling or automation infrastructure.
Built a workflow engine that runs 13x faster than Airflow, and I'm still surprised at how many teams are manually stitching together five different tools to do what Windmill does in one platform. Just crossed 69k stars. The real win: scripts become webhooks, workflows, and UIs without the boilerplate tax. If you're an infra builder or shipping internal tools, this cuts your iteration loop in half. Open source, self-hostable, no vendor lock. Worth the look.
Windmill hit 69k stars. It's the Temporal + Retool + Airflow alternative builders actually want to use. Script to webhook in one command. 13x faster than Airflow. Open source. Self-host. That's the whole pitch.
