In a context where workflow automation becomes a lever for performance and agility, n8n is generating growing interest among IT and business teams. This open source low-code platform combines over 1,100 integrations and the possibility to self-host complex workflows, all while offering an intuitive visual builder.
Compared to proprietary solutions like Zapier or Make, it promises maximum flexibility and full control. Yet, constraints related to the learning curve, cloud usage, and the “Sustainable Use” license temper this enthusiasm. This article provides a structured analysis and concrete criteria for choosing the right tool for each context.
Why Choose n8n?
n8n delivers unparalleled flexibility thanks to its open source nature and self-hosting capabilities. It allows you to create, deploy, and scale workflows with full control over your infrastructure.
Self-Hosting and Flexible Architecture
n8n can be deployed on Docker or Kubernetes, giving you the freedom to choose the infrastructure that best fits your organization’s needs. Thanks to this modularity, IT teams retain control over network configuration, resource management, and security policies. Unlike proprietary cloud platforms, this technical independence minimizes vendor lock-in risks.
A mid-sized logistics company implemented n8n on a private Kubernetes cluster. This example shows how self-hosting helped control workflow latency by placing them physically closer to their internal ERP. The responsiveness gain was deemed critical for parcel tracking operations.
The deployed architecture relies on isolated containers for each execution node, ensuring horizontal scalability. Product teams were thus able to add new workflows without impacting the performance of existing processes.
Extensibility and Customization via Custom Nodes
n8n offers a catalog of over 1,100 integration nodes, plus the ability to develop custom nodes in TypeScript. This extensibility makes it easy to connect to internal APIs, specialized databases, or third-party services. Developers can therefore meet precise business requirements without sacrificing maintainability.
In an industrial SME, a custom connector was developed to interface with an OPC-UA system on production machines. This example demonstrates n8n’s ability to adapt to industrial protocols, which enabled automated alerts in case of temperature deviations on production lines.
By combining standard nodes with custom-developed modules, teams can quickly iterate on new use cases. The open source community also contributes to enriching the catalog and sharing proven patterns.
Security and Operational Control
With self-hosting, all data remains within your company’s infrastructure, avoiding gray areas related to handling sensitive data on a third-party cloud. n8n supports OAuth2 authentication, API Key, or Basic Auth, and integrates seamlessly with secret management systems like Vault.
Granular user permission settings and detailed execution logs help prevent malicious use and facilitate internal audits.
Limitations and Constraints of n8n
Despite its strengths, n8n presents operational challenges and functional limitations. Certain obstacles may slow its adoption in complex environments.
Learning Curve and Skill Building
n8n’s visual interface simplifies the construction of standard workflows, but integrating advanced logic requires a solid understanding of triggers, JSON, and error handling. IT teams must master node internals to optimize automation robustness.
Advanced configuration of a switch or loop in n8n sometimes involves writing JavaScript functions, which requires development skills. In a heterogeneous team context, training support may be essential to ensure smooth adoption.
Without experienced resources, some pilot projects may suffer delays or encounter hard-to-diagnose bugs, particularly in multipart scenarios with advanced error management.
Cloud Limitations and AI Features
The n8n cloud version offers a hosted solution, but it is still less mature than competitors like Make or Zapier in terms of SLA availability and automatic scalability. Redundancy and high-availability options are limited, which can be problematic for 24/7 critical workflows.
Regarding AI, n8n includes nodes to call external LLMs, but fine-grained orchestration of inference chains and API quota management remain manual. Pre-configured templates for generating AI agents are fewer than on specialized platforms.
The lack of dedicated AI monitoring and fine quota settings can lead to instability, sometimes forcing teams to opt for an on-premises deployment to gain reliability.
Impacts of the “Sustainable Use” License
Since the introduction of the “Sustainable Use” license, commercial use of n8n is subject to certain restrictions, notably on the number of active workflows and execution frequency. Teams must assess whether the modified AGPL meets their legal and financial constraints.
The implications of this license require ongoing legal monitoring and regular review of the terms of use to avoid compliance issues or unexpected overcharging.

Concrete Use Cases with n8n
n8n demonstrates versatility across diverse business scenarios. Whether orchestrating processes, managing AI agents, or building data pipelines, the platform adapts to numerous uses.
Business Process Automation
Invoice approval flows, order management, or CRM/ERP synchronization are perfect candidates for automation via n8n. Teams can design workflows triggered by webhooks or scheduled times and map data precisely between different systems.
A small trading company in spare parts set up a workflow to automatically extract supplier invoices, send them to an OCR tool, then import the validated data into its ERP. This example demonstrates a 60% reduction in processing time and fewer data entry errors.
Exception handling is managed by error handling nodes that send Slack alerts to managers, ensuring proactive monitoring.
AI Agent Orchestration
n8n allows you to manage sequences of API calls to language models to generate summaries, analyze sentiment, or produce automated responses. It becomes possible to create chatbots or support agents capable of multi-step orchestration.
Prompt and result traceability is maintained in JSON storage, facilitating post-analysis and model tuning.
Integration Pipelines and Lightweight ETL
To build data pipelines, n8n can ingest streams via REST API or FTP, transform data into JSON, and load it into a warehouse or data lake. Filtering, aggregation, or cleansing operations run in Function or Code nodes.
Workflows can be scheduled according to precise SLAs and monitored via third-party hooks, providing satisfactory robustness for medium volumes. Data pipelines can thus ensure timely delivery of insights.
Criteria for Choosing Between n8n, Zapier, and Make
The choice of an automation platform depends on budget, governance requirements, and workflow complexity. Each solution comes with trade-offs that must be carefully evaluated.
Budget and Total Cost of Ownership
Zapier and Make operate on SaaS models with pricing based on the number of executions and connectors. As an open-source solution, n8n does not incur a total cost of ownership associated with hosting, maintenance, and operational upkeep.
Infrastructure costs can vary depending on whether you choose a public cloud, a local provider, or on-premise servers. It’s important to compare these recurring expenses with SaaS packages to identify the economic balance point.
For high volumes or very frequent workflows, the self-hosted option can be more cost-effective over the long term, especially if internal IT resources are already available.
Governance and Compliance
Regulated industries (finance, healthcare, public administration) require strict data management and audit capabilities. Self-hosted n8n offers full control over logs and data location. Zapier and Make may require specific subcontracting clauses.
A cantonal bank evaluated these platforms before choosing a hybrid solution: Zapier for non-critical processes, and on-premise n8n for workflows involving customer data. This example shows how to segment use according to compliance requirements.
Defining access rules, SSL certificates, and fine-grained execution traceability are critical criteria to prevent governance breaches.
Workflow Complexity and Scalability
For simple cases like email or social media synchronization, Zapier and Make are often sufficient. As soon as workflows involve loops, complex conditions, or thousands of daily transactions, n8n’s robustness and flexibility are preferable.
Make offers a user-friendly visual builder but can show limitations with nested workflows. Thanks to its code-first approach and timezone management, n8n handles critical scenarios and multipart orchestration more effectively.
Scalability is also measured by the ability to integrate new business services without reinventing each workflow. n8n’s standardized REST APIs and webhooks facilitate this functional scaling.
Choosing the Platform That Will Boost Your Agility
n8n combines open source, flexibility, and control, making it ideal for demanding workflows and stringent governance constraints. Zapier and Make remain quick-to-deploy options for less complex needs.
Self-hosting can lower the total cost of ownership in the long term but requires internal expertise for maintenance and skill development. The Sustainable Use license invites you to anticipate usage volumes.
For advanced AI automations or modular data pipelines, n8n stands out for its ability to run custom code and orchestrate multiple sequences robustly.
