Market and trust evidence

Edition not yet matched

No exact skills.sh identity match is available for this repository. Repository adoption and freshness remain visible above; install momentum is not inferred.

Trust analysis is a screening signal, not a security warranty. Read the ranking and trust methodology.

In practice

Written by AI from this repository’s README · medium confidence

Gluing devices, APIs and services together normally means writing and hosting bespoke integration code.

Use it when

When you want to build event driven flows visually and run them on a local Node.js runtime.

Not the right pick when

The README covers only quick start and development steps, so real documentation lives on the separate nodered.org site.

Capabilities

  • low code programming for event driven applications
  • browser based editor opened at http://localhost:1880
  • installed globally with npm and started with the node-red command
  • library of custom nodes, shared flows and node collections
  • buildable from source with npm ci, npm run build and npm start

Cost: Free and open source
