n8n vs Zapier: Why We Chose Open-Source Automation

When scaling business automation pipelines for B2B operations—such as multi-source lead scoring, automated CRM enrichment, and AI agent dispatch—the platform you choose dictates both your unit economics and data sovereignty.

After operating over 100,000 monthly execution tasks across client workflows, Arbizu Labs migrated entirely from proprietary cloud automation tools (Zapier / Make) to self-hosted n8n.

Here is why this transition proved pivotal.

1. Unit Economics at Scale

Proprietary platforms charge per task or operation. As pipelines incorporate complex loops, multi-step LLM evaluations, and database webhooks:

• Zapier (100,000 tasks/month): ~$600 - $900 USD / month
• n8n (Self-Hosted on $10 VPS): $10 USD / month (Unlimited executions)

By self-hosting on a hardened Docker container, execution costs dropped by > 90%, allowing us to run continuous cron monitors and real-time LLM evaluations without budgetary friction.

2. Unrestricted Code Execution & Custom Logic

Zapier restricts custom JavaScript/Python execution to isolated sandbox environments with short timeouts and no access to external npm libraries.

In n8n:

• You can write full Node.js code with any npm package.
• Direct connectivity to private databases (PostgreSQL, SQLite, Redis) inside secure VPC / Tailscale networks without exposing database ports to the public internet.
• Native integration with local AI models (Ollama running qwen2.5 or llama3) and commercial frontier models (Gemini 1.5 Pro, Claude 3.5 Sonnet).

3. Data Sovereignty & Zero Third-Party Leakage

For enterprises bound by GDPR, HIPAA, or strict NDAs, sending sensitive customer payloads through third-party SaaS automation hubs poses an unacceptable regulatory risk.

With self-hosted n8n:

• All logs, customer records, and API tokens remain in your own encrypted storage.
• Database backups and audit trails are 100% under your control.

Open-source automation offers enterprise-grade power with complete sovereignty.
