Activepieces and Windmill against n8n: which self-hosted automation to choose
n8n is not open source: its Sustainable Use License limits you to your own internal business purposes and forbids charging people to access a hosted instance. Activepieces publishes its core under MIT but keeps agents, projects and API access outside it. Windmill compiles to AGPLv3 from source, yet the distributed Community Edition is not open.
