n8n

n8n is an open-source workflow automation platform that combines the visual builder experience of tools like Zapier with the flexibility and control of self-hosting. Its AI nodes connect natively to OpenAI, Anthropic, and Hugging Face models, enabling LLM-powered automations within any workflow. n8n can be run on your own servers for complete data privacy, or used via n8n Cloud. With 400+ integrations and JavaScript execution nodes, it appeals to technical teams who need more power than no-code tools allow.
