// EDITOR'S TAKE
n8n is the closest thing to Zapier here, pairing a visual canvas with hundreds of integrations and a JavaScript escape hatch, though its fair-code licence limits what you can resell. Activepieces is the gentler option for non-technical users, while Windmill and Kestra are developer orchestrators that trade point-and-click ease for scripting and scheduling rigour.
