n8n

n8n is a workflow automation tool that combines the speed of low-code visual tools with the flexibility of full-code environments. Whether you're a developer building AI-powered agents or a business operator automating routine tasks, n8n empowers you to design multi-step automations via a drag-and-drop interface—or go deeper with custom JavaScript/Python. You can self-host for total control or opt for cloud deployment, connecting hundreds of services seamlessly. With its fair-code licensing model, open community, and strong integration ecosystem, n8n lets you automate anything, without limits on logic or deployment.

Features:

• Visual + Code Hybrid Designer: Offers a visual workflow builder for fast iteration, yet allows embedding custom logic via JavaScript or Python nodes for complex automation needs.
• Extensive Integrations Library: Boasts over 400–500 pre-built integrations (and can connect to others via HTTP requests), allowing broad connectivity across apps and services.
• Expandable AI Capabilities: Natively supports AI workflows, including AI agents via LLMs and integration with tools like OpenAI, Claude, Gemini, and LangChain.
• Flexible Deployment & Fair-Code Licensing: Gives you full ownership of your automation: self-host anywhere or choose the cloud version. The fair-code license provides transparency and security while enabling enterprise-grade deployments.
• Advanced Workflow Logic & Debugging: Supports programmable data transformations (loops, filters, merging), diverse trigger options (cron, webhooks, event streams), and powerful debugging features like partial execution and data replay.
