n8n Review: Workflow Automation Meets AI
TL;DR: n8n is one of the best open-source-style workflow automation tools going, and its AI nodes push it well past being a simple Zapier stand-in. The self-hosted version is free and capable. The fair-code licence is worth understanding but rarely a dealbreaker. For technical teams, it's better value than Zapier.
Most teams meet workflow automation through Zapier: connect two apps, set a trigger, and let the robots shuffle data around while you get on with your day. n8n starts from the same idea but pulls in a different direction. Instead of locking you into a hosted service, it hands you the engine and lets you run it on your own server, wire in your own code, and bolt AI directly into the middle of a workflow.
That last part is what's changed the conversation. A couple of years ago n8n was the thing engineers reached for when Zapier got too expensive. Now its AI nodes let you classify a support ticket, search past cases, and draft a reply inside the same flow that posts to Slack. That moves it from "cheaper plumbing" to something closer to an AI workflow engine you actually own.
The catch is that ownership cuts both ways. You get freedom and lower bills; you also get a server to maintain and a steeper first week. For a team with someone technical on hand, the trade reads well. For everyone else, the convenience of a hosted tool may still win. Here's how it stacks up.
What Is n8n?
n8n is a workflow automation platform built around a visual, node-based editor (n8n-io/n8n on GitHub):
- Hundreds of integrations, the project's own materials cite 400+ direct integrations, with many more apps reachable over HTTP
- AI nodes, LLM chains, vector stores, embeddings, and AI agents with memory and tool access
- Self-hosted, run it on your own infrastructure
- Cloud, a managed option straight from n8n
- Code when you need it, drop into JavaScript or Python for custom logic
Price: Self-hosted free | Cloud from EUR 20/mo (roughly USD 24, billed annually) | Enterprise custom (n8n pricing)
AI Workflow Builder
The AI nodes are where n8n earns its keep. You can string together something genuinely useful without leaving the editor.
Example, Support Ticket Routing:
- Trigger, new ticket in Zendesk
- AI, classify priority and sentiment
- Vector Store, find similar past tickets
- AI, draft a response
- Condition, high priority? → Alert the manager
- Action, post to Slack and update the ticket
Every node in that chain exists in n8n today, so the workflow is real and buildable. The author put it together in about ten minutes, and it returned a draft in a couple of seconds per ticket. Treat those last two figures as one person's experience rather than a benchmark; your timings will depend on the models and hardware you point it at.
Self-Hosted Performance
The table below reflects what the author saw on their own setup. n8n doesn't publish official benchmarks, and these numbers swing a lot with workflow complexity and the box you run it on, so read them as a rough field report, not guaranteed specs.
| Metric | Value |
|---|---|
| Workflow execution | 50-200ms per node |
| Concurrent workflows | 500+ (8 GB RAM) |
| Memory usage | 400 MB base |
| Startup time | 3 seconds |
| Database | SQLite (default) or PostgreSQL |
The database options are the one solid line here: SQLite out of the box, PostgreSQL when you want something sturdier (n8n docs).
vs Zapier
| Feature | n8n | Zapier |
|---|---|---|
| Price (5k ops/mo) | Free (self-hosted) | ~$73/mo (estimated from task tiers) |
| AI nodes | Built-in | Limited |
| Self-hosted | Yes | No |
| Code customisation | Full JS/Python | Limited |
| Ease of use | Medium | Easy |
| Integrations | 400+ | Thousands (Zapier cites 8,000-9,000+ apps) |
A note on the numbers: Zapier's pricing is task-based and tiered, so the $73/mo figure is a derived estimate for roughly that volume (Zapier pricing 2026), not a fixed line on the price sheet. And Zapier's app catalogue is now widely reported at 8,000-9,000+ (Zapier pricing, Lindy), well ahead of n8n's count.
The split is clear enough. Zapier wins on sheer integration count and on being easy to pick up. n8n wins on price, flexibility, and AI capability.
Pros and Cons
| Pros | Cons |
|---|---|
| Free self-hosted option | Fair-code licence, not pure open source |
| Powerful AI workflow nodes | Steeper learning curve than Zapier |
| Full code customisation | Fewer integrations than Zapier |
| Active community | Self-hosted needs maintenance |
| Strong value for technical teams | UI can feel cluttered |
Two of those cons deserve a word. The licence is the Sustainable Use License, which is fair-code rather than an OSI-approved open-source licence; it's free to self-host for internal use but carries restrictions around reselling n8n as a service. And the community is genuinely active, with the GitHub repo sitting near 193k stars, so help is rarely far away.
Verdict
Score: 8.7/10 (the author's call, not a measured figure)
n8n is the automation platform for technical teams. The AI nodes are what move it from "Zapier alternative" into AI-workflow-engine territory. Self-hosted is genuinely free and genuinely capable. If you can handle the setup, it's the best value in workflow automation right now.
