Kaff is like Goodreads, but for coffee shops. Log the spots you visit, rate them, and say what you really thought. Follow friends and fellow coffee people, and your feed turns into a running list of where everyone’s drinking and what’s actually worth the trip. Coffee, matcha & everything else counts. Rate the cortado, the ceremonial matcha, the weird lavender latte. If it’s in a cup, it belongs here. WHAT YOU CAN DO Rate and review independent coffee shops with honest takes Follow friends and see their latest finds in your feed Build your coffee passport, a record of every shop you’ve been to Browse the map to see what’s near you Add a shop that’s missing so it’s here for everyone WHY KAFF Kaff started as a group chat called Latte Raters, where friends swapped coffee shop finds. Then one of them asked, “why don’t you just build it?” So we did. It’s all about independent shops, so you won’t find a large chain. The ratings come from real people with real opinions. Made in SoCal. Pull up a seat.
