This is one of those deals that you don't realise you need until you actually start to use it!
I normally spin up a WP instance for testing using an old domain name or on local and whilst it doesn't take that long, it can be long enough to interrupt my workflow.
InstaWP is the answer! Today i've spun up 3 new sites to compare and test 3 different products and it took just moments.
I'm looking forward to diving deeper into the features such as templates, must say i'm very impressed!
