oneorzero

oneorzero is a binary signal service. A node is a single switch that holds one value - 0 or 1. You flip it, and everyone subscribed knows instantly. That's the whole idea. No feeds, no messages, no noise. One bit, delivered fast. WHAT YOU CAN DO • Create nodes - each one is a live boolean register with its own UID • Flip a node to 0 or 1 with one tap • Subscribe to any node by UID and watch it change in real time • Get a push notification the moment a node you follow flips • Name your nodes - names sync across your devices • Make a node private and share access with a token only you control FOR BUILDERS Every node is also an API endpoint. Flip it with a curl request, subscribe via Server-Sent Events or WebSocket, or register a webhook and get an HMAC-signed POST on every change. Telegram integration included. Full docs at oneorzero.one. WHAT PEOPLE USE IT FOR • Server up / server down • Stream is live / stream ended • Door open / door closed • Kettle is on, deploy finished, gate unlocked, anything binary • A quiet "I'm home safe" between two people - one tap, no conversation WHY IT'S DIFFERENT Most services deliver messages. oneorzero delivers state. A subscriber always sees the current value on connect, then every change as it happens - over push, SSE, WebSocket, or webhook. Free plan includes 10 nodes and 50,000 push notifications per month. No ads, no tracking, no analytics. Your signal history is kept for 7 days, then deleted. Sometimes one bit is all you need.
