thanks a lot @TotallyInformation , I've spent time searching in the forum and I found a similar discussion

[https://discourse.nodered.org/t/node-red-use-as-a-full-stack-backend/50392/15?u=xtwiny](https://discourse.nodered.org/t/node-red-use-as-a-full-stack-backend/50392/15)

my question is: can node-red REST API handle a million users or more but must use multiple instances?  
can you explain to me how it's done?  
I searched for node-red multiple instances and i found something like that  
node-red -p 1881 -u /home/_ **/** _/_ **/** _  
node-red -p 1882 -u /home/_ **/** _/_ **/** _  
node-red -p 1883 -u /home/_ **/** _/_ **/** _  
is thats mean i make different clone my node-red API in many folders and make it working in different paths?  
if its a true, how it does working?  
if solving is correct , how can i do that?
