n8n claims vs. our reality
n8n markets itself as an open-source, low-code tool for connecting apps and automating tasks, with growing AI capabilities through features like AI Transform Nodes and the Self-Hosted AI Starter Kit.
From our hands-on testing, the AI integration capabilities are genuinely impressive. Our team built multiple AI agents that would have cost hundreds monthly with traditional services. For instance, our team created an AI agent to automate product research on Vinted, replacing multiple paid bots. It was faster, more customizable, and free because it was self-hosted.
The ability to inject custom JavaScript or Python directly into nodes gives immense power for developers. Want to preprocess data before sending it to GPT-4? Easy. Need to parse AI responses and route them differently? Built-in.
However, building sophisticated AI workflows still requires technical knowledge. While the visual builder works for basic AI tasks, complex AI logic like our multi-LLM routing system took real development effort. Non-technical users will find services like Zapier's AI features more plug-and-play.
How does n8n handle AI workflow automation?
Let's break down how n8n's AI capabilities translate to real-world business value, based on the AI agents and workflows our team built.
Can n8n build custom AI agents that actually work?
This is where n8n truly shines for AI automation. Our team built several production-ready AI agents that went far beyond simple "if-then" logic. Here's a look at what we actually built.
Summarizing LinkedIn posts with AI: Our team was burning 5-6 hours every week manually scrolling through the LinkedIn feed. The goal was to spot emerging content trends and find relevant posts for our marketing team to engage with. We built an AI agent in n8n that's hooked directly into our team's daily chat on Discord. We set up a dedicated #link-submissions channel where anyone on the team can simply paste the URL of an interesting LinkedIn post they find.
The moment a link is shared, our n8n workflow triggers. It automatically scrapes the post's content, feeds it to a Gemini-powered AI Agent for a concise summary, and then publishes that summary to our main #market-intelligence channel. The result is a fully automated insight pipeline.
Invoice processing AI bot: This bot was built to handle a messy inbox. The workflow kicked off with a Gmail trigger that detected new emails with PDF attachments and would upload the file to a dedicated Google Drive folder.
From there, the AI Agent node, powered by Gemini, got to work. It would first classify the document to figure out if it was a receipt or an actual invoice. Only if it was an invoice, the agent would then intelligently extract the key data like invoice date, description, total price and map everything automatically into an Excel sheet. It wasn't just grabbing text; it was actually understanding the document first.
AI customer support with contextual memory: We also built a Telegram-based knowledge assistant using n8n. The goal was to let users ask questions and get context-aware answers pulled from multiple curated sources. We used OpenAI for the language model and wired it to several 'Book Expert' nodes, each representing a different knowledge base.
Instead of giving generic replies, the agent routed queries to the most relevant source before responding. We also added a Simple Memory node so the agent could hold short-term context across messages. This made the interaction feel more natural and less repetitive. It worked reliably and showed how n8n can power intelligent support bots.
These weren't just one-off projects. We spun up other agents, like one using MongoDB Atlas for vector search to query our internal documents, and another that could understand natural language questions like "how many new signups from Germany this month?" and pull specific data directly from Airtable. The real power of n8n is this ability to chain multiple AI models, add custom logic between the steps, and integrate with virtually any API to build a genuinely custom AI solution that works exactly how you need it to.
How does n8n's self-hosting benefit AI workflows?
n8n's open-source nature delivers massive cost savings for AI automation. While not all of us are DevOps experts, one of our team members with server admin experience handled the setup and management of our instance.
A basic VPS to run n8n costs around $5-10/month, making complex AI automations incredibly cost-effective. His key observation, which our team valued, was that when you're making hundreds of AI API calls daily, avoiding per-execution fees from platforms like Zapier saves serious money.
More importantly, self-hosting means your data never leaves your servers before reaching the AI model. For sensitive business data processing, this control is invaluable. This setup allowed to process confidential invoices and customer data knowing exactly where everything went.
What n8n AI features actually move the needle?
AI transform node: Lets you apply AI transformations to data without complex API calls. We used it to clean messy CSV data before analysis and to generate product descriptions from specifications.
Custom AI model integration: Unlike rigid AI automation tools, n8n connects to any AI service. We built workflows using OpenAI, Anthropic, Google's models, and even used LangChain for routing. One workflow automatically tested the same prompt across multiple models to find the best response.
Memory and context management: The Memory nodes let AI agents remember previous interactions. Our customer service AI bot maintains conversation context across days, making interactions feel natural.
How easy is n8n AI implementation & integration?
Setting up n8n's AI features requires some technical comfort, but the process is straightforward for developers. The cloud-hosted version gets you started fastest, though we opted for a self-hosted setup, managed by one of our team members, for greater data control.
n8n supports over 400 pre-built integrations, including AI services. We connected OpenAI, set up webhook triggers, and had a basic AI workflow running in under an hour.
The real power comes from combining AI nodes with n8n's other integrations. Our invoice AI agent seamlessly connected Gmail, Google Drive, OpenAI, and Excel - creating a complete automated pipeline that traditional tools would struggle to match.
Self-hosting demands technical skills for installation, updates, and security. We quickly found that as our AI workflows scaled, we encountered "SQLITE_BUSY" errors once the database grew (around 4-5GB) from storing AI conversation logs. The solution was to migrate the database to PostgreSQL. We also noted that for high-volume AI workflows with lots of webhook triggers, adding Redis for Queue Mode was essential. These observations underscored the technical realities of maintaining a robust self-hosted instance.
What about n8n AI support & documentation?
n8n's AI documentation covers the basics well. Setting up AI Agent nodes and connecting to major AI services is well-documented. The community contributes useful AI workflow examples.
For practical learning, n8n's official YouTube channel is an excellent resource. It features real-life use cases from startup users who directly share their sales, marketing or even cybersecurity automation workflows. Seeing these production-ready examples provides immense value, and we definitely recommend checking it out.
What are n8n's AI limitations & deal-breakers?
Here's what our team flagged as potential issues for AI workflows:
Learning curve for AI workflows: Building sophisticated AI agents requires understanding both n8n's workflow logic and AI model behaviors. Simple AI tasks are approachable, but complex multi-step AI workflows need technical expertise.
AI error handling: When AI models fail or return unexpected responses, n8n's error handling works but isn't as robust as dedicated AI platforms. We built custom error handling, but it required extra development time.
Token usage monitoring: Unlike AI-specific platforms, n8n doesn't provide detailed AI token usage analytics out-of-the-box. For cost control on large AI workflows, you'll need custom monitoring.
Real-time AI notifications: The error handling exists, but we found it lacked robust real-time notifications for silent AI workflow failures without custom setups. Critical for production AI agents.
How does n8n AI pricing compare to alternatives?
n8n's pricing structure, especially its self-hosted option, makes it exceptionally cost-effective for serious AI workflows. Here's our conclusive breakdown of how it stacks up against the competition.
n8n (free self-hosted edition; cloud plans start at €20/month)
n8n offers a free, open-source Community Edition, where you only cover server costs (~$10/month for a basic setup). Its official cloud plans start at €20/month for 2,500 executions, scaling fairly with plans like €120/month for 50,000 executions, all with AI features included.
For technical teams, n8n is the definitive choice for building custom AI solutions. Self-hosting provides total data control, enabling fully air-gapped environments that are ideal for businesses with strict security and data sovereignty needs. While there's a learning curve, the result is an infinitely flexible and cost-effective platform that can't be outgrown.
Pipedream (free tier available; paid plans start at $29/month)
Pipedream offers a generous free tier with 300 credits/month and paid plans that start at $29/month for 2,000 credits. Its credit system is developer-friendly, as one credit covers 30 seconds of compute time, meaning most of our multi-step test workflows only consumed a single credit.
Pipedream is a compelling, developer-centric alternative that sits neatly between Zapier's simplicity and n8n's raw power. It's an excellent choice if you want a managed, pro-code environment without the setup of a self-hosted instance. However, for maximum cost efficiency and data sovereignty on high-volume AI tasks, a self-hosted n8n instance remains unbeatable.
Zapier (free tier available; plans scale with task volume + add-on costs)
Zapier provides a free tier for 100 tasks/month, with paid plans scaling aggressively based on task volume (e.g., $129/month for 10,000 tasks). Critically, its core AI features, like Chatbots and Tables, are priced as separate monthly add-ons, which can significantly inflate the final bill.
Frankly, Zapier's simplicity is a trap for scalable AI automation. The platform is fantastic for non-technical users and simple "if-then" connections, but its costs become astronomical for the kind of custom, high-volume AI agents we built. Technical teams will hit the ceiling on both its capabilities and its pricing model very quickly.
Make (free tier available; plans from $29/month)
Make has a free tier with 1,000 operations/month, and its paid plans are priced similarly to n8n's cloud offerings, with plans like its $99/month Teams tier providing 40,000 operations. Its primary advantage is an extensive library of over 2,000 app integrations, which is fantastic for broad connectivity.
However, Make is less flexible for developers wanting to build complex, custom logic. While powerful as a low-code tool, it doesn't offer the same freedom as n8n to inject custom JavaScript or Python directly into workflows. This makes n8n the superior choice for developers who need to write custom code and have granular control over their AI automations.
