Why Nebuchat?

We've reimagined secure messaging with privacy at its core. No compromises, no backdoors, simple true security.

End-to-End Encryption

Every message is encrypted from sender to receiver using AES-256 encryption protocols. Only you and your recipient can read your conversations.

Decentralized Servers

Host your own server. No central authority means no single point of failure or surveillance.

No Account Registration

Communicate without sharing personal information. No email, no phone number, just a unique ChatID for connect chats.

Secret Key Protection

Messages remain encrypted until the correct secret key is entered. Even if your device is compromised, your conversations stay secure.

How End-to-End Encryption Works

See for yourself how Nebuchat keeps your messages secure from prying eyes.

Secure Communication Flow

When you send a message with Nebuchat, it's encrypted on your device using AES-256 before being sent to the recipient. Only the intended recipient with the correct secret key can decrypt and read the message.
