For example In other words, Can we able to run on different ports The application running in http://127.0.0.1:1880/ and the other in http://127.0.0.1:1881/

That has already been answered. By giving each instance its own userDir (-u) they each have their own settings file and catalogue.json file.

When running multiple instances, you need to use different workspaces (default is .node-red in your user dir) using the -u DIRECTORY parameter when starting Node-RED (depending on how you start it, of course).

If you want Node-RED to load a catalog from http://localhost:1880/catalogue.json then you need to do something to set that up http endpoint. The palette.catalogues setting assumes your are providing URLs. One option to make that catalogue available would be to use the httpStatic setting - that can…

I have given, but still, it didn't work out Please find screenshots below [image] [image] [image]

the httpStatic property should be set to the directory containing catalogue.json - not the file itself.

[image] knolleary: directory containing You mean I just need to give for httpStatic in settings.js file as below httpStatic: 'C:/Users/usre/.node-red/static/'

Yes. Sorry, I see I got my instructions wrong previously. I have edited that reply to correct it.
