CyberPub is a temporary, anonymous 1:1 web chat styled like a cyberpunk bar. Step in, grab a private table for two, chat, and once you leave, the conversation vanishes without a trace. No public profiles, no history, and no permanent message database. Powered by Supabase and Web Crypto API, it features a rolling buffer of the last 10 messages, sector rooms, and an immersive sci-fi vibe.
