You can actually develop offline in Roblox Studio, the only thing you can’t do is test the game. I think SharkBlox did cover this, I’m not to sure!
I don’t think Sharkblox has covered this, at least, not yet.
He has, I saw a video of him testing Roblox Studio while being offline.
Roblox studio can be used offline, it’s just putting it into a front end, safe to use profit is difficult.
