Nixvoid - Anonymous, zero-registration encrypted real-time chat.

Nixvoid is a web-based, zero-footprint chat platform. No phone numbers, no emails, no sign-ups. Connect instantly and chat anonymously. Every message is secured purely client-side using native Web Crypto API (AES-GCM 256-bit). Once read, messages auto-destruct in 10 seconds and are permanently wiped from the DOM and our signaling servers. Features include Ghost Mode, Incognito Read, and customizable themes—all stored strictly in your local browser. Complete privacy by design.

Hi Product Hunt! 👋 I’m the solo developer behind Nixvoid. I built this because I grew tired of "secure" messaging apps demanding my phone number, email, and accessing my contacts before letting me talk to anyone. Nixvoid is an experiment in extreme minimalism and zero-knowledge architecture. There is no user database. Encryption (AES-GCM 256-bit) happens purely in your browser via the Web Crypto API, and the backend server only acts as a dumb transit layer for the ciphertext. To combat physical device snooping (the "Analog Hole"), messages automatically self-destruct 10 seconds after rendering. We also have "Ghost Mode" (no typing indicators) and "Incognito Read" (no read receipts). I'd love for the PH community to try breaking it, test the UI, or give me harsh feedback on the concept! I'll be here all day answering your questions.
