I'm using NativeRest. It's working in offline mode, you can use only local workspaces (scratchpad). And it also uses less than 10 MB of RAM.

NativeRest is currently actively developing and GraphQL support will of course be added in the future. There will also be a version for Mac.

Yes, cloud workspaces are supported, but if user doesn't create them or login, then no data will be sent to the servers.

NativeRest is a lightweight REST client and does not require a login.

Try NativeRest, if you use Windows
