n8n – fair-code 工作流自动化平台 2026：可视化节点 + AI Agent + MCP，Zapier 的自托管答案

n8n 是什么？What Is n8n?

n8n（读作 "n-eight-n"，n8n.io）是 2019 年由 Jan Oberhauser 在柏林创立的工作流自动化平台，定位是「可自托管的 Zapier」：可视化节点画布把几百个应用串起来，任意节点都能插一段 JavaScript 或 Python 做自定义逻辑。截至 2026 年 10 月，其 GitHub 仓库约有 20.8 万 Star（历史前 30），是自动化品类里社区动能最强的项目。n8n (pronounced "n-eight-n", n8n.io) is a workflow automation platform founded in Berlin by Jan Oberhauser in 2019, positioned as "the self-hostable Zapier": a visual node canvas that wires hundreds of apps together, with custom JavaScript or Python injectable at any node. As of October 2026, its GitHub repository holds roughly 208k stars (top 30 of all time) — the strongest community momentum in the automation category.

2026 年的 n8n 已经不只是自动化工具，而是智能体工作流底座：原生 AI Agent 节点、完整的 MCP 客户端支持、LangChain 集成，以及 2026 年 1 月上线的 human-in-the-loop 人工审批；2026 年初还发布了 n8n 2.0。官方公布的规模：每月 670 万活跃工作流、1,400+ 企业客户、170 万月活开发者与搭建者（2026-05），以及 SAP 投资后的 €52 亿估值——这些数字来自 2026 年 10 月柏林首届 n8n 大会 In the Loop 的开幕演讲。The 2026 n8n is no longer just an automation tool — it is an agentic workflow substrate: native AI Agent nodes, full MCP client support, LangChain integration, and human-in-the-loop approval shipped in January 2026, plus n8n 2.0 released early in the year. Official scale figures: 6.7 million active workflows per month, 1,400+ enterprise customers, 1.7 million monthly active developers and builders (May 2026), and a €5.2 billion valuation after SAP's investment — announced at n8n's first conference, In the Loop, in Berlin in October 2026.

许可与价格是选型前必读的两页。许可证是 Sustainable Use License 1.0（fair-code）：给自己公司或个人用、随便改、免费自托管都没问题，但不能把它包装成托管服务卖给客户。计费按执行次数：一个 20 步的工作流跑一次只算 1 次执行（Zapier 按任务数计费，2024 年还涨价 40%）。Cloud Starter 约 €24/月（含 2,500 次执行），自托管社区版免费且执行不限量（2026-10 核实，以官网为准）。License and pricing are the two pages to read before adopting. The license is the Sustainable Use License 1.0 (fair-code): use it for your own company or personal projects, modify it freely, self-host for free — but you may not sell it as a hosted service to customers. Billing is execution-based: one run of a 20-step workflow counts as 1 execution (Zapier bills per task and raised prices 40% in 2024). Cloud Starter is about €24/month for 2,500 executions, while the self-hosted Community Edition is free with no execution limit (checked October 2026; see the official site for current prices).

n8n 是「自动化」这个老品类里唯一成功长成「智能体底座」的玩家：别人还在拼集成数量，它已经把 AI Agent 节点、MCP、人工审批做进了工作流引擎。€52 亿估值和 20.8 万 Star 说明市场已经投票。它的计费模型是真正的降维打击——按执行次数而不是按任务数，高频场景下比 Zapier 便宜一个数量级。但它的学习曲线是真实存在的：节点画布对非技术用户不如 Zapier 的线性步骤直观，fair-code 许可证也堵死了「基于 n8n 做 SaaS 转售」这条路。结论很清晰：技术团队、要自托管、要 AI 智能体，闭眼选 n8n；纯业务团队、怕运维，老老实实付 Zapier 的钱。

n8n is the only player in the old "automation" category that successfully grew into an "agent substrate": while others still compete on integration counts, it has baked AI Agent nodes, MCP, and human-in-the-loop approval into the workflow engine. The €5.2B valuation and ~208k stars show the market has voted. Its billing model is a genuine disruption — per-execution instead of per-task, an order of magnitude cheaper than Zapier at high volume. But the learning curve is real: the node canvas is less intuitive for non-technical users than Zapier's linear steps, and the fair-code license closes the "build SaaS on n8n" path. The verdict is clear: technical teams that want self-hosting and AI agents should pick n8n without hesitation; purely business teams afraid of ops should just pay for Zapier.
