How complex is self-hosting n8n?

For a basic deployment, n8n runs as a single Docker container on any VPS — configuration takes less than an hour for a developer familiar with Docker. For production environments, we deploy n8n with PostgreSQL (instead of the default SQLite), a reverse proxy (Nginx or Caddy), SSL termination and automated backups. Ascii-Core handles all infrastructure setup and ongoing maintenance for clients.

Is n8n significantly cheaper than Zapier?

For high-volume automations, yes — substantially. Zapier's per-task pricing scales linearly with automation volume. A workflow running 50,000 tasks per month could cost $500+ on Zapier. Self-hosted n8n adds only infrastructure costs (typically $20–$50/month for a VPS). n8n Cloud (managed) starts at approximately $20/month with a flat fee regardless of task count.

Is n8n GDPR and CNDP compliant?

Self-hosted n8n is inherently compliant with data residency requirements — all data, credentials and workflow execution logs stay within your own infrastructure. This satisfies GDPR requirements for EU data and Morocco's CNDP data protection obligations. Cloud-based automation tools like Zapier and Make process data through their own servers, which requires trust in their DPA and security certifications.

Can n8n integrate with OpenAI and Anthropic Claude?

Yes. n8n includes native nodes for OpenAI (GPT-4o, embeddings, DALL-E), Anthropic Claude and several other LLM providers. These nodes handle authentication, streaming responses and structured output — enabling AI steps within automation workflows without writing API code. We build AI-powered n8n workflows for document processing, email triage, customer support routing and data enrichment.

n8n is an open-source, self-hostable workflow automation platform with 400+ native integrations and built-in LLM nodes for OpenAI and Anthropic. Unlike SaaS alternatives, n8n can be deployed on your own infrastructure — keeping all data, credentials and workflow logic within your control. Licensed under Apache 2.0 with a fair-code distribution model.

Why we chose it

Why Ascii-Core uses n8n

1
Self-hosted deployment keeps sensitive data on client infrastructure — essential for GDPR and CNDP compliance
2
Flat-rate pricing (not per-task) makes cost predictable as automation volume grows
3
Native OpenAI and Claude integration nodes — AI steps are first-class, not bolted on
4
Open source — no vendor lock-in, full access to source code, community of 50,000+ users

Ideal use cases

When to use n8n

CRM, ERP and SaaS integration workflows
AI-powered document processing pipelines
WhatsApp Business and communication automation
Scheduled data sync between systems
Complex multi-step workflows with branching logic that would be expensive in Zapier

Trade-offs

Honest limitations

We believe in accurate trade-offs. These are the cases where a different tool may be the better choice.

Requires infrastructure management when self-hosted — not suitable for teams with no DevOps capability
Smaller native integration library than Zapier (400 vs 6,000) — though any REST API is accessible
Visual builder has a steeper learning curve than Zapier for non-technical users
