Overview

Description

Windmill lets your engineering team turn scripts into internal tools, APIs, and automated workflows without needing a separate frontend team or multiple platforms. It replaces Retool-like UI builders and Temporal-like workflow engines with a single self-hosted solution. The bottom line: ship internal apps and automations in hours, not weeks.
