> The name is just for identification
That’s precisely what they’d dislike about it. You’d be creating “brand confusion” by using their trademark in your own name. You couldn’t make “My Cola (Recreating Coke)” without getting an expensive and inconvenient letter from their legal team.
It's also worse than that. It uses the Raycast logo directly in the launcher itself. Which is odd because just above this, OP says:
"I've actually thought about that before; I've tried to be extremely clear in the project's README with a disclaimer that this is a non-commercial hobby project and is not affiliated with the official Raycast team in any way."
Clearly a bright kid, but that's quite a fumble. Among my ideas for being extremely clear about not being affiliated with Raycast I would have to say using their name and using their logo together would be the worst way to communicate that.
It's worse than that -- "Recreating Raycast" is just the blog post title, the project is called "raycast-linux".
