n8n is an open-source, AI-native workflow automation platform that lets UK small businesses connect apps, automate processes, and build AI agents — all while keeping data on their own infrastructure. With 400+ integrations, a visual drag-and-drop editor, and full self-hosting capability, n8n has rapidly become the automation tool of choice for businesses that want GDPR-compliant workflows without the per-task pricing of Zapier. This review covers the 2026 pricing, features, self-hosting options, and whether it delivers for your UK business.

What Is n8n?

n8n (pronounced "n-eight-n") is an open-source workflow automation platform that started as a fair-code alternative to Zapier. It was created in 2019 by Jan Oberhauser, who wanted a self-hostable automation tool that didn't charge per task. Today, n8n has grown to over 50,000 GitHub stars and serves businesses ranging from one-person startups to enterprise teams.

The core idea is simple: you build workflows by connecting nodes in a visual editor. Each node represents an action — send an email, update a spreadsheet, call an API, run an AI prompt. The visual editor shows the data flowing between nodes in real time, making it easy to debug and iterate. Unlike Zapier, which abstracts away complexity, n8n gives you full visibility into what each step does. For UK small businesses that need to automate custom workflows — particularly those handling sensitive customer data — n8n's open-source, self-hostable architecture provides control that proprietary tools cannot match.

In 2024 and 2025, n8n added significant AI capabilities including AI agent nodes, vector store integrations, and direct LLM connections. This means you can build AI-powered workflows — such as a customer support bot that reads your knowledge base, summarises tickets, and drafts replies — all within the same platform. n8n Cloud launched in 2022 and now offers managed hosting with plans starting at approximately £18/month.

Pricing (GBP)

*Prices converted from USD at approximately 1.27 USD/GBP. VAT at 20% may apply. Annual billing saves ~15%. n8n Cloud is hosted in EU data centres. Self-hosted Community Edition is completely free with no feature limitations — ideal for UK businesses needing full data control.

Key Features

n8n's visual workflow editor is the heart of the platform. You drag nodes onto a canvas, connect them in sequence, and configure each step through a form-based interface. Every node shows incoming and outgoing data in real time, so you can see exactly what information flows between steps. This makes debugging dramatically easier than the black-box approach of most SaaS automation tools. The editor supports branching, looping, error handling, and conditional logic — giving you the same power as writing code, but visually.

The 400+ integrations cover the full range of tools UK businesses use: Gmail, Google Sheets, Slack, Notion, QuickBooks, Xero, Shopify, Stripe, HubSpot, Salesforce, and hundreds more. Each integration is community-maintained on GitHub and receives regular updates. If an integration does not exist, you can use the HTTP Request node to call any API directly, or write custom JavaScript or Python code in a Code node. This flexibility means n8n can handle workflows that would require a developer to build from scratch on other platforms.

The AI agent functionality is where n8n differentiates itself from Zapier and Make. You can connect to OpenAI, Anthropic Claude, Google Gemini, or local models via Ollama, then give the agent tools — search your database, send emails, create calendar events, browse the web. The agent decides which tools to use based on your prompt, enabling autonomous workflows. For example, you could build an AI customer support agent that reads your FAQ, checks your CRM for the customer's order status, and drafts a personalised reply — all running on your own infrastructure with your data staying in the UK.

Self-hosting is n8n's killer feature for UK businesses. You can deploy it on a £5/month VPS from Hetzner UK, DigitalOcean London, or your own on-premise server using Docker. The entire application — database, execution engine, webhook receiver, and UI — runs in a single container. Once deployed, you have unlimited workflows, unlimited executions, and full control over data residency. For a business handling customer data, this is worth far more than the £18/month you would spend on Cloud Starter just from a compliance perspective.

The Sub-workflow feature lets you nest workflows inside each other, enabling modular automation design. You can build reusable sub-workflows for common patterns — send invoice, notify team, log to spreadsheet — then call them from any parent workflow. This keeps your automations organised and maintainable as they grow. Enterprise plans add SSO/SAML, audit logging, and user roles, making n8n suitable for teams that need governance around their automation infrastructure.

Pros and Cons

Is n8n Right for UK Small Businesses?

n8n is the right choice for any UK business that values data sovereignty and needs automation with depth. If you are processing customer data, financial information, or any data subject to UK GDPR, self-hosting n8n on a UK-based VPS gives you compliance that Zapier and Make cannot match — those platforms process data in US servers with varying data protection agreements. For a small business paying £5-10/month for a Hetzner VPS plus free n8n Community Edition, the total cost is lower than any cloud automation plan, with better compliance.

For businesses that prefer a managed solution, n8n Cloud Starter at ~£18/month is competitive with Make (Core at ~£7/month for 10,000 operations) but offers more integrations and custom code flexibility. Where n8n really shines is AI agent workflows — the ability to combine LLM calls with your business tools in a single, self-hosted platform is something no other mainstream automation tool offers at this price point. A UK business could build a GDPR-compliant AI assistant that reads their CRM, sends personalised emails, and updates their accounting software — all without data leaving their infrastructure.

Where n8n falls short is simplicity. If you just need to connect two apps with a simple trigger-action pattern and have no interest in how it works under the hood, Zapier or Make will get you there faster. n8n rewards investment in learning. The platform is excellent for technically-minded founders, small teams with developer support, or anyone who has outgrown Zapier's limitations. If you are comfortable with basic JSON, APIs, and Docker, n8n will save you significant money and unlock automations that would require a developer on any other platform.
