Node-RED
Fully open-source, flow-based programming that runs on hardware as small as a Raspberry Pi.

sovereigntyNode-RED is a mature, Apache-2.0 flow-based automation tool built on Node.js. You wire together "nodes" in a browser editor to move and transform data between APIs, webhooks, MQTT, databases, and thousands of community-contributed integrations. It is the most sovereign option here on licensing and hardware: it runs locally, stores flows as open JSON files, and is light enough for a Raspberry Pi. Its roots are in IoT and event automation rather than SaaS-to-SaaS connectors.

What it does well
- +Fully open-source under Apache-2.0, an OSI-approved license
- +Runs entirely locally on modest hardware, including a Raspberry Pi
- +Flows are stored as open JSON files you own and can version-control
- +Huge library of community nodes and a long, stable track record
- +Excellent for IoT, webhooks, MQTT, and custom logic
Where it falls short
- −Flow-based, developer-leaning model; less turnkey than Zapier's app-picker for connecting SaaS tools
- −Many SaaS integrations rely on community nodes that vary in quality and maintenance
- −You maintain the runtime, updates, and any exposed endpoints yourself
- −Building polished multi-app business automations takes more effort than a no-code UI
