If you use n8n for automations involving large language models (LLM), you probably know not only about their huge capabilities but also about the risks. LLMs remain a “black box”: they can accidentally disclose personal data, generate toxic content, or fall victim to prompt injection.
Until recently, you had to “wrap” an AI workflow with many IF nodes and complex Regex checks. It was cumbersome and unreliable.
Since version 1.119.0 n8n includes the Guardrails node — and it’s truly a game-changer. It’s your personal security layer that you can place at the input and output of any AI process.

n8n is a powerful open-source workflow automation tool that allows building complex workflows without deep programming. One of the key scaling mechanisms in n8n is queue mode, where the main instance delegates task execution to separate processes called workers. Workers allow distributing load, enabling parallel workflow execution and improving system performance.
In the n8n community and practical guides, two types of workers are often distinguished: light workers and heavy workers. Although the official documentation doesn’t use these terms directly, they reflect differences in task types and configuration. Light workers are aimed at fast, frequent operations, while heavy workers handle resource-intensive tasks. In this article we’ll examine their differences, how they work, and why they are necessary for effective scaling.

n8n + Xano: A Powerful No-Code Backend for Scalable Applications
In the final article of our series on n8n integrations with backend services, we’re taking a closer look at Xano — a no-code/low-code platform for building scalable APIs and databases without writing server-side code.
If you need a flexible, fast-to-deploy backend with support for scalability and automation, the Xano + n8n combination is an excellent choice.
What Is Xano?
Xano is a cloud platform for visually building backends and APIs. Under the hood, it runs on PostgreSQL, while on the surface it offers a powerful API Builder for creating logic, DB operations, and integrations — all without writing code.

n8n + Appwrite: An Open-Source Firebase Alternative for Self-Hosting
We’ve already explored Supabase and Firebase — now it’s time to look at Appwrite, a powerful and fully open-source BaaS platform designed for self-hosting and complete data control.
If you want to build a backend on your own infrastructure, Appwrite can be the perfect partner in combination with n8n.
What Is Appwrite?
Appwrite is a full-featured Backend as a Service (BaaS) platform with open-source code. It provides REST APIs for most features a modern application needs:

n8n + Firebase: NoSQL, Realtime Database, and Cloud Functions for Dynamic Apps
After reviewing Supabase and its PostgreSQL-based architecture, let’s turn to another powerful BaaS platform — Firebase by Google. Firebase takes a completely different approach: NoSQL, real-time data sync, and deep integration with the Google Cloud ecosystem.
If your app needs real-time updates, schema flexibility, and strong mobile support, the Firebase + n8n combo might become your key automation tool.

n8n and the World of Databases: Why Automating Backends and BaaS Matters
In our previous article series, we explored the worlds of monitoring and logging, as well as how n8n helps automate routine tasks by connecting various web services. But what if your data isn’t in Google Sheets or a CRM, but instead lives in structured storage — databases or cloud-based backend platforms?
That’s where n8n truly shines — as a bridge between data and action.
