About
n8n (pronounced "n-eight-n") has rapidly become the preferred automation tool for developers and privacy-conscious businesses. Headquartered in Berlin, it distinguishes itself from Zapier by being "fair-code" (source-available), allowing users to host the platform on their own servers for free or use the managed cloud version for a fee. This self-hosting capability is a massive advantage for European companies that need to strictly adhere to GDPR by keeping data within their own infrastructure.
The platform uses a node-based visual interface where you connect different apps via wires to create workflows. Unlike many no-code tools that hide complexity, n8n embraces it, allowing users to write custom JavaScript within nodes for infinite flexibility. This makes it significantly more powerful than standard automation tools for complex data transformation tasks.
n8n supports hundreds of integrations (nodes) out of the box, from Google Sheets and Slack to Telegram and PostgreSQL. Because it can be self-hosted, it has no "per-task" pricing limits in the free version—you are only limited by your own server's performance. For technical teams who find Zapier too expensive or limiting, n8n is the ultimate alternative.
