// EDITOR'S TAKE

n8n is the closest overall, pairing hundreds of prebuilt integrations with JavaScript and Python nodes for the parts no connector covers, though its fair-code licence restricts commercial resale. Windmill fits better if you think in scripts rather than canvases, turning TypeScript or Python files into workflows and internal UIs, while Activepieces stays firmly no-code and is the easiest of the three to hand to non-engineers.
