This Week in StartupBase #28
Last Thursday, I launched MacBase, a place to discover the best Mac apps.
In its first week, 161 apps were listed, about 230 people signed up, and the domain rating went from 0 to 44.
Built a Mac app, or building one? List it for free and get a backlink. You can even ask Claude or ChatGPT to list it for you.
