What is Windmill?
Windmill is an open-source developer platform that turns scripts into production-grade workflows, scheduled jobs, APIs and internal tools — combining the flexibility of code with the convenience of a low-code platform. It's aimed at developers and technical teams who want to automate processes and build internal applications without the limitations of pure no-code tools or the overhead of building everything from scratch. You write logic in real languages (Python, TypeScript, Go, Bash, SQL and more), and Windmill handles turning that into scalable, reliable automation.
The platform's versatility is its strength. From individual scripts, Windmill lets you build multi-step workflows with a visual flow editor, schedule jobs with cron, expose logic as APIs and webhooks, and create internal app UIs and admin tools on top of your code. This means a single platform can replace a patchwork of automation tools, internal tooling frameworks and job schedulers, all while keeping your business logic in maintainable, version-controllable code rather than locked inside a proprietary visual builder. It handles execution, dependencies, secrets, permissions and observability so you don't have to.
Being open source, Windmill can be self-hosted for full control, privacy and cost efficiency — appealing strongly to teams that want to own their automation infrastructure — with a cloud option available too. It's designed for performance and scale, and supports collaboration so teams can build and share scripts, flows and apps. This makes it a powerful fit for engineering, data and operations teams that need to automate workflows, run scheduled jobs, and build internal tools quickly while retaining the power and maintainability of code. For developers who find no-code automation too limiting but don't want to build and operate their own automation stack from zero, Windmill offers a flexible, open and genuinely powerful platform that bridges the gap.
