Co•fé - Find your place. Find your people. Working from cafés should be the best part of remote work. Most days, it's not quite there. You're not sure if your laptop is welcome. You bought one coffee two hours ago and you're thinking about it. You're working. People are around. But you're still on your own. A friend lives ten minutes away - you haven't seen each other in weeks. No big problems. Just small things that make the day feel harder than it needs to. Co•fé gives you one simple thing: a way to show you're here - and choose how open you are to others, right now. No planning. No messaging strangers. No performance. FIND YOUR SPOT Cafés where your laptop is genuinely welcome - with Wi-Fi, power, and coworking details verified by people who actually work there. Not Google reviews. Real information. KNOW WHO'S AROUND See when friends check in nearby. Know when someone you know is at the café down the street. No coordination needed. Just awareness - and the option to join. SAY HI Not a message. Not a match. Just a signal. One tap that says: I'm here, you're here, come say hello if you want. The rest happens face to face - or it doesn't. Either way, no one's left on read. OPEN TO A HELLO Choose to be visible to other people working nearby. It's not a friend request - it's a signal that you're around. You decide each time you check in. GROUPS Join or create a group for your coworking crew, study group, or neighbourhood regulars. Simple containers that help the right people find each other - no feeds, no chat. ADD ANY CAFÉ Co•fé is community-driven. Every place added by people who work there. Add your favourite café, rate it, share photos, and help others find their next spot. Everything is opt-in. You choose when you're visible and to whom. Built by people who love cafés. For everyone who does too. Available in English, German, French, Italian, and Spanish.
