n8n

Open-source workflow automation platform that connects apps and APIs with a visual interface and optional code-level control.

What is n8n?

n8n is an open-source workflow automation tool that lets you connect apps, APIs, and AI models through a visual drag-and-drop interface.

Unlike pure no-code tools, you can drop into JavaScript whenever you need custom logic or complex data transformations. It's self-hostable, which means you control your data and can run it on your own infrastructure.

Builders use it to automate everything from customer onboarding flows to AI agent pipelines. Popular for connecting OpenAI, databases, and business tools without writing full backend code. Works well for both simple Zapier-style automations and complex multi-step AI workflows.

Free self-hosted version available. Cloud hosting starts at $20/month. Over 400 integrations including Slack, Google Sheets, Postgres, and major AI APIs.
