// EDITOR'S TAKE
Activepieces is closest in spirit, with a no-code canvas, AI steps and human-approval pieces you can drop into a flow. n8n has far more connectors and raw power but its node graph assumes some engineering comfort, and Automatisch is cleaner to run with a much thinner integration catalogue.
