Open-source platform to turn scripts into internal apps & workflows
Windmill is an open-source developer platform that turns scripts into workflows, internal tools, and full-stack apps. Write scripts in Python, TypeScript, Go, Bash, Rust, SQL - Windmill auto-generates UIs from their parameters, handles dependencies, credentials, permissions, and scheduling so you focus on business logic, not infra. Open-source alternative to Airflow, Temporal, Retool and n8n. Chain scripts into flows with branching, parallelism, retries. Build dashboards with the app builder. Trigger via cron, webhook, or UI. All-in-one runtime, editor, secret manager, and OAuth platform - enterprise-ready out of the box. Stack: Rust / TypeScript + Svelte / PostgreSQL. Self-hostable, easy to deploy, built for performance and DX.
Windmill is an open-source, code-first orchestration platform to build, share, and run internal software, including scripts, workflows, internal apps, and data pipelines. It emphasizes self-hosting, Git-based collaboration, and full code flexibility for enterprise-scale governance and observability.
Windmill turns scripts written in languages like TypeScript, Python, Go, Bash (and 20+ others) into executable APIs, triggers, and auto-generated forms. It provides a built-in script editor, flow editor, and app builder accessible from the browser, plus a CLI for local development and AI-assisted coding. Work lives in a Git-versioned workspace with resources, databases, roles, permissions, and auditability. It supports self-hosting via Docker or Kubernetes, scales from single nodes to large clusters, and offers enterprise features like RBAC, SSO, secret management, and comprehensive logs and alerts. The platform unifies scripts, workflows, internal apps, and data pipelines under one orchestration layer with granular access control and observability.
Who it’s for: Engineering teams, data teams, and IT/DevOps teams in mid-to-large organizations needing internal tooling, automation, and custom app/workflow orchestration at scale.

Customer case studies and enterprise-focused features; mentions of self-hosted deployments and enterprise edition imply active traction and ongoing development
Ruben was top of his class MSc in CS at EPFL, did research on compilers from Scala to Hardware at Stanford, built the first open-source library for reinforcement learning for Java, , built distributed systems at scale at Palantir and ran the engineering team at a Multi-Party Computation startup. He is now building Windmill, an open-source alternative to Retool, Pipedream, Airplane that contains the infra to run it and that you can deploy at scale.
Fully open-source developer platform to turn any python, typescript, SQL into internal apps, integrations and workflows
Windmill is an open-source developer platform that converts scripts in Python, TypeScript, Go, Bash, and SQL into production-grade internal apps, workflows, and integrations. It targets teams needing self-hosted automation and provides app generation from code or GitHub, with runs via triggers, webhooks, or schedules, and an emphasis on inspectable, tweakable modules.
