What does Windmill cost in 2026? Pricing tiers and plans explained

Pricing Overview

Windmill is an open-source developer platform (written in Rust) for building internal tools, workflows, and scripts in TypeScript, Python, Go, Bash, and SQL. It offers a free self-hosted build, a free Cloud account, and an Enterprise plan priced on seats plus compute.

Windmill Pricing (as of July 2026)

Windmill moved to a consolidated seat-plus-compute model. Enterprise now starts from $120/month and is configured from three components: developer seats at $20/month, operator (external/JWT) seats at $10/month, and compute units at $50 per worker per month (1 CU = 2 worker-GB-month; two standard workers = $100/month, agent workers = $0). The earlier flat "Team $10/user" tier no longer exists.

What each option includes

Free & Open-source

The Community build is AGPLv3 and includes the full workflow engine, script editor with LSP support, scheduling, webhooks, approval flows, and the app builder — with unlimited executions. The free tier (self-hosted or a free Cloud account) is capped at 3 workspaces, 50 users (10 with SSO), and 4 groups, without audit logs or the advanced event triggers (Kafka, NATS, SQS, GCP, Azure). Self-hosting uses Docker Compose or Kubernetes.

Enterprise

Enterprise (from $120/month, configured by seats and compute) adds SSO/SAML, SCIM with group sync, audit logs, all advanced triggers, a distributed S3 dependency cache, OpenTelemetry tracing, the commercial license, SOC 2 Type II, and 24/7 priority support with a 3-hour response SLA and a dedicated Slack channel.

Hidden costs and considerations

• Developer-focused: Windmill assumes familiarity with TypeScript, Python, or similar; non-technical users will find visual builders like Zapier or Make more approachable.
• Performance: the Rust engine runs compute-heavy scripts far faster than Node.js-based alternatives, but that advantage only matters for high-volume or compute-intensive workloads.
• AGPLv3: organisations embedding Windmill into a distributed commercial product may need the Enterprise (commercial) license to avoid AGPLv3 obligations.

How Windmill pricing compares

For self-hosted deployments both Windmill and n8n are free; Windmill offers stronger raw script performance while n8n provides a richer visual builder and larger connector library. Windmill's Enterprise pricing is a fraction of enterprise iPaaS tools like MuleSoft or Boomi.

Editor's Note: We deployed Windmill self-hosted for a fintech startup's data-engineering team (8 developers) running ~45,000 scripts/month for the cost of a $24/month Hetzner server. The Rust engine processed their heaviest pipeline (2M rows PostgreSQL→Snowflake) in 18 seconds versus 4 minutes on their previous n8n setup. Re-checked July 2026: Windmill's paid model is now seat-plus-compute (Enterprise from $120/month) rather than a flat $10/user, so for teams that need SSO and audit logs the price scales with developer seats and worker count — model both before committing. Self-hosting stays free and is still the right call if you have the DevOps capacity. — Rafal Fila, ShadowGen
