Windmill Chain

Windmill offers an open-source workflow engine and developer platform for building, orchestrating, and monitoring internal software at scale. It enables developers to transform scripts into auto-generated UIs, APIs, and cron jobs, compiling them into robust workflows and data pipelines. The platform provides high performance, scalability, and enterprise-grade security, delivering self-hostable solutions to reduce engineering overhead.

The company was founded by Ruben Fiszel, a solo founder from Y Combinator's Summer 2022 batch. His insight focused on developers needing full code control and flexibility, thereby avoiding vendor lock-in for internal tooling. Fiszel aimed to simplify the creation and scaling of internal applications, eliminating the need for extensive custom infrastructure.

Windmill serves engineering teams and developers across sectors, who leverage its platform for critical applications like business automations, AI workflows, and ETL. The company’s vision is to empower teams to efficiently manage sophisticated internal platforms, championing open-source principles, seamless integration, and robust reliability.
