n8n
n8n.io
Fair-code workflow automation platform — visually connect apps and APIs like Zapier, but self-hostable with no per-task pricing.
Why it is useful
n8n combines a drag-and-drop workflow builder with the ability to drop into actual JavaScript/Python code for custom logic, giving it more flexibility than most no-code automation tools. Self-hosting removes the per-execution costs that make Zapier expensive at scale, and it ships with hundreds of pre-built integration nodes.
