Insights, guides, and stories about building and scaling products with no-code tools — faster, smarter, and without traditional coding.
n8n is an open-source workflow automation tool for developers who want control without heavy coding, a key point in many n8n reviews. Unlike drag-and-drop platforms targeting non-technical users, n8n shines by allowing embedded JavaScript and custom code where needed for greater flexibility.
Its self-hosted setup means no recurring SaaS fees and full ownership of your automation stack—perfect for teams that want flexibility and privacy combined.
By 2024, running your own automation platform is easier than ever. Thanks to Docker and container tech, tools like n8n install quickly on your personal or cloud servers—often in under 10 minutes for a smooth n8n Docker installation process.
This slashes monthly fees you’d pay on cloud platforms and gives you total control over data and customization.
If you have basic cloud skills, self-hosting cuts costs dramatically without sacrificing power. For example, a $5/month Hetzner VPS can run n8n smoothly versus $20+ per month on hosted alternatives. That delta matters when you scale workflows or run multiple automations continuously.
Self-hosting is not just about cost; it’s about owning your automation edge. The next step? Master straightforward setup and protect your systems with solid reverse proxies and HTTPS.
Installing n8n is a matter of a few Docker commands. You spin up the container, and your workflow editor is accessible via a web interface on local or remote ports. For production, a reverse proxy (like nginx) is standard—it secures traffic using HTTPS and forwards requests smoothly to n8n, making a reliable n8n webhook reverse proxy setup important.
Certificate management can be outsourced to providers like Let’s Encrypt or managed through proxy services, taking the complexity off your hands. The whole install can be production-ready in well under an hour.
n8n stands out for its deep JavaScript integration. You write JavaScript directly inside nodes or in dedicated "Code nodes." This means transforming JSON responses or tweaking data flows happens with native JS syntax, not a limited builder UI or proprietary scripts.
Bonus: In self-hosted versions, you can import npm packages inside code nodes—adding an entire JavaScript ecosystem to your workflow. That’s rare for low-code platforms and gives your automation tons of flexibility with n8n JavaScript integration.
These code nodes run sandboxed to keep your server secure—no direct file system or free reign network access—so you get power without risk.
Since early 2023, n8n supports Python via Pyodide, which runs Python inside JavaScript environments by compiling to WebAssembly. This is more resource-heavy and needs code blocks specifically, but it broadens your automation toolbox with n8n Python code execution.
If you need Python-specific libraries or syntax beyond JavaScript, this is your in-platform solution—no need to cobble together external services or custom scripts.
APIs are automation’s backbone, and n8n nails it with HTTP request nodes. A slick feature: copy-paste your existing cURL commands directly into these nodes. No rewriting, minimal friction.
Secure credential storage lets you save API keys or tokens once and reuse them across many workflows securely. This makes connecting to third-party APIs—from web scrapers such as ScrapeNinja API integration to CRM systems—fast and manageable.
Self-hosting isn’t without its learning curve, especially with OAuth integrations like Google’s APIs. Unlike cloud SaaS platforms where OAuth setup happens behind the scenes, you must manually register your n8n instance in Google Cloud Console, configure scopes, and manage credentials with Google OAuth setup for n8n.
This step requires patience and some comfort with Google’s developer tools. But once done, it unlocks powerful secure connections that cloud vendors often oversimplify at a premium.
n8n splits into Community and Enterprise Editions, both self-hosted. Community Edition is free, covers core features, and fits most internal or business automations. Enterprise adds advanced options but often isn’t worth extra cost for day-to-day needs.
Self-hosting overall slashes recurring fees typical of cloud automation providers, which charge by usage—the number of tasks or compute time. For example, n8n Cloud’s entry plan starts at $20/month, but unlike competitors billing per action, it keeps pricing flat regardless of workflow complexity in an n8n pricing comparison.
Hosting costs shape your bottom line more than you think. Hetzner leads with $5/month VMs (4GB RAM, 2 vCPUs) while DigitalOcean or Linode charge around $24 for similar specs. For startups and small teams, this delta can mean months of runway or the ability to add more automations without breaking the bank, making Hetzner cloud hosting for n8n highly recommended.
Choosing the right host means balancing cost, uptime, and support. If your budget is lean, smart selection here is non-negotiable.
n8n is designed for developers and users comfortable with some coding, particularly JavaScript, as it allows embedded code to customize workflows. However, it offers a low-code environment that may be accessible with learning, unlike purely no-code platforms.
n8n allows secure credential storage for API keys and tokens, enabling safe reuse across workflows. This approach secures connections to third-party services without risking sensitive data exposure.
Self-hosting n8n provides full control over your automation environment, eliminates recurring SaaS fees, and enhances privacy and customization options, key reasons highlighted in many n8n reviews.
Yes, since early 2023, n8n supports Python code execution via Pyodide, enabling Python scripts to run inside the JavaScript environment, which broadens automation possibilities beyond JavaScript.
Setting up OAuth, such as Google OAuth, requires manual steps in the Google Cloud Console, including registering your n8n instance and configuring scopes. This process can be technically demanding compared to cloud SaaS platforms.
n8n nails the sweet spot for teams wanting open-source workflow automation with deep JavaScript power and emerging Python support for n8n reviews. Self-hosting lets you ditch SaaS fees, lock down your data, and flexibly customize automations at scale.
Sure, there’s a technical step up—especially around OAuth and infrastructure setup—but that’s the tradeoff for control and cost efficiency. If you’re ready to build smart, sexily lean automations, n8n is your toolkit (n8n reviews).
