What Is Windmill

Windmill is an open-source, code-first orchestration platform designed for building internal software. Founded in 2022 by Ruben Fiszel and backed by Y Combinator and investors including Bessemer Venture Partners, the company operates out of Paris and San Francisco and has grown to serve thousands of organizations, including hundreds of enterprise customers.

The core idea behind Windmill is that internal tools, automations, and data pipelines should be built from ordinary code rather than proprietary low-code building blocks. Scripts written in Python, TypeScript, Go, PHP, Bash, or SQL can be turned directly into runnable tools, scheduled jobs, or multi-step workflows.

Windmill automatically generates user interfaces for scripts and flows, letting teams go from a raw script to a usable internal application quickly, while still keeping the underlying logic in standard, portable code rather than a vendor-specific format.

Key Features

Windmill supports multiple languages in a single platform and represents workflows as DAG-based flows that capture task dependencies, enabling complex automations and data pipelines to be built and visualized clearly.

Collaboration is Git-native, with entire workspaces version-controlled, and teams can share resources and set granular permissions across scripts, flows, and apps. Enterprise-grade controls include role-based access control, SSO, secret management, and audit logging.

The platform can be self-hosted via Docker, Fargate, or Kubernetes, or run on Windmill's managed cloud, and it emphasizes execution speed, positioning itself as one of the fastest job orchestrators available for internal tooling and automation use cases.

Pricing

Windmill follows an open-core pricing model. The Free and Open-Source tier costs nothing, supports unlimited executions, up to 50 users, three workspaces, and 10 GiB of object storage, with community Discord support and some limits such as 10 SSO users.

The Enterprise tier starts at 120 per month and unlocks unlimited workspaces, executions, audit logs, and job retention, along with SAML with group sync, distributed caching, advanced observability, and 24/7 priority support.

Enterprise pricing scales with optional add-ons, including developer seats at 20 per month, operator or external JWT user seats at 10 per month, and standard or native subworkers at 50 per month each, billed monthly or annually with no additional usage-based metering.

Pros & Cons

Pros

  • Genuinely free, full-featured open-source self-hosted tier
  • No vendor lock-in since logic is written in mainstream programming languages
  • Fast job execution engine suited to high-throughput automation
  • Supports a wide range of languages in one platform
  • Backed by credible investors and growing enterprise customer base

Cons

  • Requires coding skills, making it less accessible to non-technical users than pure low-code tools
  • Enterprise features like SAML group sync and unlimited audit logs are gated behind the paid tier
  • Per-seat and per-worker add-on pricing can increase Enterprise costs as usage grows
  • Smaller community and ecosystem compared to more established automation platforms
