n8n
Open-source workflow automation with full code control
n8n is the workflow-automation platform for teams that want real control: a visual builder that drops down to JavaScript or Python, native AI-agent nodes, and a self-hosted Community Edition that is genuinely free with unlimited workflows. Setup asks more of you than a plug-and-play tool, but for technical teams the depth, execution-based pricing, and zero lock-in make it a clear Strong Buy.
