Why self-host or switch automation platforms? More →
Zapier, Make and similar tools charge by task or operation. High-volume workflows get expensive fast, and your business data flows through a third-party cloud.
Open-source automation tools (n8n, Activepieces, Node-RED, Windmill, Automatisch and others) can run on your own server. You keep credentials and payloads inside your network.
Every listing states its licence carefully — including fair-code and source-available licences that are not OSI open source — so you know what you can self-host and what needs a commercial agreement.
