If you've ever automated workflows with Zapier or Make (formerly Integromat), you probably ran into their limitations: prices that scale fast, restrictions on the number of executions, and, above all, the impossibility of self-hosting the tool on your own servers. n8n is the open source alternative that is gaining ground in LATAM thanks to its flexibility, its transparent pricing model, and the possibility of running everything on your own infrastructure. In this article we explain what n8n is, how it compares to Zapier and Make, and how to install it on a VPS from Argentina.

What n8n is and why it's growing so fast

n8n (pronounced "nodemation") is an open source workflow automation platform, created by Jan Oberhauser and released under a "fair-code" license (Sustainable Use License). Unlike Zapier and Make, n8n lets you download the source code, deploy it on your own server, and modify it according to your needs. According to the official n8n documentation, the platform has more than 400 native integrations and a community that is growing exponentially.

What makes n8n especially attractive for technical teams and companies in LATAM is the combination of three factors: predictable cost (you can self-host it for free), total data privacy (nothing leaves your server), and flexibility to integrate AI directly into the flows.

n8n vs Zapier vs Make: a detailed comparison

Key advantages of n8n for teams in LATAM

1. Total control over your data

In a context where data protection regulations are tightening across the region, being able to self-host your automation platform is a huge differentiator. With self-hosted n8n, all the data from your flows stays on your server. This is critical if you handle sensitive client data, financial information, or health data.

2. Predictable and scalable costs

Zapier's model scales fast: if you need 10,000 monthly executions, you're already paying more than USD 49/month. With self-hosted n8n on a basic VPS (USD 5-10/month), you have unlimited executions. For startups and SMEs in Argentina that bill in pesos but pay for tools in dollars, this difference is significant.

3. Native AI integration

n8n incorporated LangChain nodes directly into its visual editor. This means you can build AI agents, connect with models from OpenAI, Anthropic, Ollama (local), and others, process documents with RAG, and execute complex chains, all without leaving the n8n interface. According to the official n8n blog, AI flows represent more than 30% of the automations created by the community.

4. Active open source community

n8n has a very active global community that shares workflows, resolves questions, and contributes new integrations. There is an official forum, a Discord server, and hundreds of ready-to-use templates. In LATAM, the Spanish-speaking community is growing rapidly, with virtual meetups and dedicated channels.

How to install n8n on a VPS from Argentina

Installing n8n on your own server is simpler than you think. We show you the step-by-step process using Docker, which is the method recommended by the official documentation.

Prerequisites

• A VPS with at least 1 GB of RAM and 20 GB of storage (providers like DigitalOcean, Hetzner, or Contabo work well from Argentina).

• Docker and Docker Compose installed.

• A domain pointing to your VPS's IP (optional but recommended for HTTPS).

Step 1: Connect to the VPS via SSH

Open your terminal and connect to the server. Once inside, make sure you have Docker installed and working correctly.

Step 2: Create the docker-compose.yml file

Create a directory for n8n and inside it a docker-compose.yml file with the service configuration. Define the environment variables for the timezone (America/Argentina/Buenos_Aires), the base URL of your instance, and the credentials of the PostgreSQL database that n8n will use to persist the data.

Step 3: Bring up the service

Run docker compose up -d and wait a few seconds. n8n will be available on port 5678 of your server. If you configured a domain with a reverse proxy like Nginx or Caddy, you can access it via HTTPS.

Step 4: Configure the credentials

From the n8n web interface, configure the credentials of the services you want to connect: Gmail, Slack, Google Sheets, OpenAI, databases, etc. The credentials are stored encrypted on your server.

Real use cases with n8n

These are some flows that teams in Argentina and LATAM are implementing with n8n:

• AI lead scoring: When a lead comes in through a form, n8n enriches it with LinkedIn data, scores it using an AI model, and assigns it to the right salesperson in the CRM.

• Competitor price monitoring: A workflow that scrapes competitor prices daily, compares them with yours, and sends alerts via Slack when there are significant changes.

• Invoice processing: Receive invoices by email, extract the data with OCR + AI, automatically load them into your accounting system, and generate a weekly summary.

• AI customer support: An AI agent connected to your knowledge base that answers frequent queries on WhatsApp, escalates complex cases to a human, and records everything in a Google Sheet.

• Automated content pipeline: Generate article drafts with AI, send for review via Slack, publish on WordPress, and share on social media, all automatically.

n8n and integration with AI models

One of the areas where n8n stands out against Zapier and Make is in the integration with artificial intelligence models. The platform includes native nodes for:

• OpenAI: Chat completions, embeddings, image generation with DALL-E, text-to-speech, and speech-to-text.

• Anthropic (Claude): Completions with the Claude models for complex reasoning tasks.

• Ollama: Connection with local models, ideal for maintaining total data privacy.

• LangChain: Nodes that implement agents, chains, memory, and retrieval augmented generation (RAG) directly in the visual editor.

• Vector stores: Integration with Pinecone, Qdrant, Supabase, and others for semantic searches.

This ability to combine traditional automation with advanced AI in a single visual interface makes n8n an especially powerful tool. According to TechCrunch, automation platforms that integrate native AI are growing three times faster than those that don't.

Limitations of n8n you need to know

No tool is perfect. These are the most important limitations of n8n:

• Fewer integrations than Zapier: With 400+ nodes versus Zapier's 7,000+, it's possible that some specific integration doesn't exist. However, n8n allows you to create custom nodes and has a generic HTTP node that lets you connect with any API.

• Learning curve: n8n is more powerful but also more complex than Zapier. If your team doesn't have a technical profile, the learning curve can be steep.

• Self-hosting requires maintenance: If you choose to self-host, you have to take care of updates, backups, and server monitoring. For teams without DevOps, n8n Cloud is the simpler alternative.

• Uneven documentation: While the official documentation is good, some newer nodes have limited documentation. The community compensates to a large extent with tutorials and templates.

Frequently asked questions

Is n8n really free?

The self-hosted version of n8n is free and open source under the Sustainable Use License. You can download it, install it on your server, and use it at no cost. The only expense is the server (VPS), which starts from USD 5/month. n8n Cloud, the hosted version, has paid plans from USD 20/month.

Can I migrate my flows from Zapier or Make to n8n?

There is no automatic migration tool, but the logic is transferable. n8n has equivalent nodes for most of the popular Zapier and Make integrations. In general, recreating a medium-complexity flow takes between 1 and 3 hours, depending on the number of steps.

Is n8n safe for sensitive data?

In its self-hosted version, n8n is as secure as your server. All the data stays in your infrastructure, the credentials are stored encrypted, and there is no mandatory telemetry. This makes it more secure than cloud tools for cases where data privacy is critical, like health, finance, or regulated personal data.

Do I need to know how to program to use n8n?

It's not strictly necessary, but it helps. n8n has a visual drag-and-drop interface that lets you create flows without code. However, to take advantage of its full potential (JavaScript expressions, code nodes, complex data transformations), basic programming knowledge is a significant advantage.

Can I use n8n to automate WhatsApp Business?

Yes. n8n integrates with the WhatsApp Business API through the official node and also via intermediary services like Twilio or Meta's API directly. You can create flows that respond to messages automatically, send notifications, or connect WhatsApp with your CRM.
