Could you please help me getting Remix IDE run in an offline environment? I've researched that way from google but found no answers for it.
Yes, you can use it. Check out here.
You can connect it to a wide range of VMs, testnets, RPCs, even some L2 !
I find it very useful because it has access to my computer's file system. No need to connect buggy Remix-D anymore, and you can use it even offline without a connection !
I still wonder why not so many people use the Desktop version !
