n8n (short for Node-mation) is an open-source workflow automation platform that uses a node-based interface to build complex processes. Unlike most competitors, n8n allows for self-hosting, providing users with complete data privacy and a way to bypass “per-step” pricing limitations. n8n has become the premier tool for building advanced AI agents, thanks to its deep integration with LangChain and top-tier large language models.
Key Features
- Self-Hosting: Run n8n for free on your own infrastructure (via Docker) with no limits on tasks or workflows.
- Code Nodes (JS/Python): Execute custom JavaScript or Python code directly within any step of your automation for complex logic.
- Advanced AI Layer: Built-in nodes for autonomous AI agents, vector store connections, and long-term agent memory.
- Binary Data Support: Robust handling of files (images, video, documents) throughout the automation process.
- Execution-Based Pricing: On the cloud version, you are billed per successful workflow run, regardless of how many steps are inside.
Main Use Cases
- Developers & DevOps: Building secure internal automation tools while maintaining strict data governance.
- Security Operations (SecOps): Automating cyber incident response and real-time log analysis.
- AI Developers: Constructing RAG systems and intelligent customer support agents.
- Tech Companies: Managing massive database synchronizations and ETL processes without high recurring costs.
- Technical Non-Developers: Building sophisticated apps that require logic beyond the capabilities of simpler tools.
Pricing Plans
- Community Edition (Self-hosted): Free. Includes core features and unlimited executions (requires own server maintenance).
- Starter Plan (Cloud): €20/month (billed annually). Includes 2,500 executions per month and managed hosting.
- Pro Plan (Cloud): €50/month. Includes 10,000 executions, execution history search, and user permission management.
- Business/Enterprise Plan: Starting around €667/month. Includes Git integration, SSO, multi-environment support (Dev/Prod), and SLA.
Pros and Cons
Pros:
- Total freedom – no limits on creativity or data volume in the self-hosted version.
- Best market value for heavy, complex automation needs.
- Cutting-edge AI and agentic features for low-code environments.
Cons:
- Steeper learning curve requiring technical familiarity (JSON, APIs, JavaScript).
- Self-hosting requires server management, updates, and security oversight.
- Smaller library of native integrations (~400+) compared to Zapier, though HTTP nodes allow connecting to any API.
