Windmill review

Windmill suits teams whose n8n workflows have turned into code nodes with a little canvas around them. Every step is a script, written in Python, TypeScript, Go, Bash, SQL, Rust or other supported languages, and those scripts compose into flows, data pipelines, AI agents or full React and Svelte apps. The free self-hosted Community Edition has unlimited executions, up to 50 users, 3 workspaces and SSO for 10 users, and the repository is published under AGPLv3 and Apache 2.0. Paid Enterprise starts from $120 a month and is priced on seats and compute: the page lists $20 a month per builder, $10 per non-builder and $50 per standard worker, with a calculator to model your setup. Enterprise adds audit logs, SAML, Kafka and SQS triggers, a commercial license and 24/7 support. Business users will find it less approachable than a drag and drop tool.
