n8n vs. Zapier: Choosing the Right Automation Engine
EU IT-Ops teams are revisiting their SaaS stacks as task-based billing, GDPR exposure and AI add-ons drive up Zapier budgets. What if you could keep the ease of low-code workflows without paying per task - or shipping data to the U.S.? n8n is a source-available alternative that runs anywhere from a cloud VM to your own rack.
Where Zapier costs add up
- Rising subscription spend: Zapier's Professional plan costs $29.99 a month for 750 tasks with monthly billing. At 100 000 tasks the same plan costs $733.50 a month and the Team plan $898.50 (Zapier pricing, October 2026). Tasks beyond the limit cost more than the tasks in the plan, depending on plan and billing cycle (Zapier help), an unpredictable tax on growth.
- GDPR & Schrems II risk: Zapier hosts data on AWS servers. Every trigger, payload and AI prompt traverses borders, triggering Article 5(1)(f) headaches and vendor-lock-in fears.
- AI surcharges: Need ChatGPT in your flows? Prepare for double billing: Zapier plus OpenAI per-token fees. Our own research shows how token fees grow with volume, especially with agents that call the model several times per document.
What drives these bills is the unit Zapier counts. The same four-step workflow shows the difference:
Zapier counts a task for every action that runs, so the AI step with a standard model and the write to the ERP use one task each, while the trigger and the Formatter step are free (Zapier help). Stronger AI models use 3 or 5 tasks per step (Zapier task usage rates). n8n counts one execution for the run of the whole workflow, however many steps or items it handles (n8n pricing). The more steps a workflow has, the further the two counts drift apart.
What n8n does differently
- Self-hosted n8n: Unlimited workflow executions, users and steps. n8n Cloud starts at €20 a month for 2 500 executions with annual billing (n8n pricing, October 2026), but the community edition is free - just add a VPS.
- Local AI Agents with Ollama: Follow our guide to run LLMs locally with Ollama & n8n to cut latency and AI spend at high volumes.
- Governed automation: S&S Technologies layers RBAC, audit trails and custom Matrix42 node to bring ITSM, ERP and AI together in one governed pipeline. Automate. Optimize. Scale.
Building the same workflow in both
Side-by-Side Build Experience
| Step | Zapier | n8n |
|---|---|---|
| Trigger | Gmail new email (no task) | Gmail node (0 extra cost) |
| Parse | Formatter step (no task) | Built-in Code node |
| LLM | AI by Zapier (1 task with a standard model, 3 or 5 with stronger ones) | Local SLM |
| Post to ERP | Premium app on a paid plan (1 task) | Free HTTP Request node |
Result: Zap with 4 steps = 2 tasks with a standard AI model. n8n = 1 execution, unlimited operations.
Spin-up in < 10 minutes
# on a small VM with Node.js 22
npx n8n # starts n8n on port 5678
curl -fsSL https://ollama.com/install.sh | sh # installs Ollama
ollama pull mistral # downloads a 7B model
Add the Ollama Model node in the n8n canvas, point the credentials to http://localhost:11434 and you're chatting with a local model - no Internet, no token fees.
Deep ERP & ITSM Integration
Our Matrix42 node lets you raise, update and close tickets inside the same flow that your SLM just summarised. Need SAP or Jira Service Management? Connect them through their APIs with the HTTP Request node, use one of the more than 2 000 integrations listed on n8n.io or write your own in JavaScript.
Local SLM vs. Cloud GPT
- Latency: no round trip to a cloud provider
- Cost: electricity instead of a fee for every token
- Data residency: External → On-prem
(Source: Run Local LLMs with Ollama & n8n)
The difference is easiest to see in the path an email takes through an AI workflow:
With Zapier and a cloud model, the content passes through two services outside your company: the model provider and Zapier, which stores customer data on AWS in the USA (Zapier). With self-hosted n8n and Ollama, workflow and model run on your own server, so no third party processes the content between inbox and ERP.
Costs and results compared
- Cost savings
Zapier Professional (2 000 tasks) costs $49 a month with annual billing vs. €0 for self-hosted n8n (plus the cost of a server). At 20 000 tasks, Zapier Team costs $249 a month (Zapier pricing, October 2026); n8n cost stays flat.
AI: an agent that calls GPT-4 Turbo five times per invoice costs about $175 a month for 1 200 invoices and about $1 450 for 10 000. A €1 800 workstation with a local model pays for itself in about a year in the first case and within two months in the second.

- Simpler GDPR compliance: with self-hosting, workflows and vectors stay on your own servers, with no transfer abroad that would need Standard Contractual Clauses. n8n Cloud keeps data in Frankfurt but its Data Processing Agreement still includes the SCCs (n8n).

How to plan the move
- Audit your Zaps. Identify high-volume flows and premium app dependencies.
- Estimate AI spend. Multiply GPT token costs by monthly volume - then compare to local SLM electricity.
- Pilot n8n + Ollama. Use the script above or book a guided Proof-of-Concept.
- Plan migration. Our team ports workflows, sets up RBAC and integrates ERP, ITSM and process-mining dashboards.
