n8n

n8n is an open-source workflow automation platform that connects your apps and services with a visual node-based editor. Think of it as a self-hostable alternative to Zapier and Make, but with the ability to add custom JavaScript or Python code at any step. n8n offers 400+ integrations with popular services including Slack, Gmail, Google Sheets, Notion, Airtable, PostgreSQL, Stripe, GitHub, and more. The visual workflow builder lets you drag and connect nodes, with each node representing a trigger, action, or transformation. What sets n8n apart is its code flexibility: you can write custom functions, make HTTP requests, parse data with expressions, and handle complex branching logic that visual-only tools struggle with. n8n supports webhooks, scheduled triggers, polling, and event-based execution. Error handling includes retry logic, error workflows, and notifications. The self-hosted version is completely free with no limits on workflows or executions, and you can run it via Docker or npm. n8n Cloud offers a managed experience with team collaboration, execution history, and uptime monitoring. For developers and technical teams who need automation power beyond what Zapier offers, n8n provides the perfect balance of visual simplicity and code-level control.
