n8nとは？

n8n is an open-source workflow automation tool that offers both self-hosted and cloud-hosted deployment options. It provides a visual workflow editor with the flexibility to add custom code, appealing to developers who want control over their automation infrastructure.

What is n8n?

n8n (pronounced "nodemation") is an open-source, extendable workflow automation platform. It provides a visual node-based editor for building integrations and automations, with the distinguishing feature of being self-hostable — giving teams full control over their data and infrastructure.

How n8n Works

n8n workflows consist of nodes connected on a canvas:

  • Trigger nodes: Start workflows based on events, schedules, or webhooks.
  • Action nodes: Connect to 400+ services including databases, APIs, and SaaS tools.
  • Code nodes: Write custom JavaScript or Python for complex transformations.
  • Flow control: IF conditions, switches, loops, and merge nodes for orchestration.

    • n8n's Strengths

  • Self-hosting option: Run n8n on your own servers for complete data sovereignty and compliance.
  • Open source: Inspect, modify, and extend the codebase. Community-contributed nodes expand the ecosystem.
  • Code-friendly: Developers can drop into JavaScript or Python anywhere in the workflow.
  • Fair pricing: The cloud version offers more generous limits than comparable commercial platforms.

    • n8n's Limitations

  • No browser automation: n8n cannot natively interact with web pages or perform browser-based tasks.
  • Smaller connector library: Fewer pre-built integrations compared to Zapier or Make.
  • Self-hosting overhead: Running your own instance requires DevOps expertise and ongoing maintenance.
  • No AI agent: Workflows must be designed manually — there is no AI assistant to build them from descriptions.

    • n8n vs. Zapier

    n8n offers more flexibility and lower costs, especially for self-hosted deployments, while Zapier provides a larger app library and simpler onboarding. n8n appeals to developers; Zapier appeals to business users.

    なぜ重要か

    n8n demonstrates that workflow automation does not require vendor lock-in. Its open-source model gives technically capable teams full control over their automation infrastructure, though this freedom comes with the responsibility of self-management.

    Autonolyのソリューション

    Autonoly provides the visual workflow building experience of n8n combined with AI-powered browser automation and an intelligent agent — without requiring self-hosting or DevOps expertise. Teams get the power of a code-capable platform with the convenience of a managed service and the added ability to automate any website through browser control.

    例

    • A developer team choosing between self-hosting n8n and using Autonoly's managed platform for production automation

    • Extending an n8n-style workflow with Autonoly's browser automation to scrape data from a website without an API

    • Using Autonoly's AI agent to generate a workflow that would take hours to build manually in n8n's visual editor

    よくある質問

    n8n's source code is available under a fair-code license (Sustainable Use License). You can self-host it for free, but there are restrictions on providing n8n as a service to others. The cloud-hosted version (n8n Cloud) is a paid product with tiered pricing based on workflow executions.

    n8n offers self-hosting, custom code nodes, and more affordable pricing. Zapier offers 6,000+ app connectors, easier setup, and no infrastructure management. n8n suits developer teams that want control; Zapier suits business users who want simplicity.
