How Svellora Works
Svellora makes private conversations effortless. Unlike traditional messaging apps that require phone numbers, email addresses, and lengthy sign-up processes, Svellora strips everything down to what matters most: your conversation.
Here is how it works in three simple steps:
- Create a Room — Click "Create New Room" and choose any display name you like. Svellora generates a unique, randomized room code instantly.
- Share the Code — Send the five-character room code to the person you want to chat with. They can join from any device with a modern web browser.
- Start Talking — Once both of you are in the room, end-to-end encryption activates automatically. Your messages are encrypted in your browser before they ever leave your device.
When you are done, simply close the tab. The room, the messages, and all encryption keys are destroyed permanently. There is nothing to delete, no history to clear, and no trace left behind.
Key Features
End-to-End Encrypted
Svellora uses the Web Crypto API built into modern browsers to implement Elliptic Curve Diffie-Hellman (ECDH) key exchange. Each participant generates a unique key pair when they join a room. The browsers exchange public keys and derive a shared secret that is used to encrypt every message with AES-GCM. The server never has access to your encryption keys and can only see encrypted ciphertext — it is mathematically impossible for anyone, including Svellora's own servers, to read your messages.
No Account Required
There is no sign-up form, no email verification, and no phone number linking. You never create a username or password. Just pick a temporary display name for the current session and start chatting. Your identity remains completely under your control, and Svellora never collects or stores any personally identifiable information.
Completely Anonymous
Svellora does not track IP addresses, device fingerprints, or browsing behavior. There are no analytics cookies following you around the web. The platform is designed from the ground up to know as little about you as possible — because true privacy means the service itself cannot compromise your anonymity, even if compelled to do so.
Ephemeral by Design
Unlike other messaging platforms that store your messages on cloud servers indefinitely, Svellora has no database at all. Messages exist only in active browser memory and are relayed in real time through encrypted WebSocket connections. The moment both participants close their browser tabs, the chat room and all associated data are permanently and irrecoverably destroyed.
Real-Time Messaging
Built on WebSocket technology, Svellora delivers messages with sub-50-millisecond latency. You will see typing indicators, read receipts, and instant message delivery — all the responsiveness of a modern chat app, with none of the privacy trade-offs. The experience feels as fast and fluid as any mainstream messaging platform.
Why Choose Svellora?
Privacy First
In an era where every message, photo, and call is logged, analyzed, and monetized by big tech companies, Svellora offers a fundamentally different approach. We believe privacy is not about hiding secrets — it is about protecting intimacy. Whether you are discussing sensitive business matters, sharing personal thoughts with a close friend, or simply want a conversation that is not being harvested for advertising data, Svellora provides a safe digital space.
Instant Connections
There is no app to download, no software to install, and no permissions to grant. Svellora runs entirely in your web browser on any device — desktop, laptop, tablet, or phone. Create a room in under two seconds and start a conversation immediately. The five-character room codes are short enough to share via text, email, or even verbally.
Open and Transparent
Svellora's encryption implementation uses well-established, browser-native cryptographic primitives. We do not rely on proprietary encryption protocols or closed-source libraries. The entire encryption process — key generation, key exchange, message encryption, and message decryption — happens transparently in your browser using standard Web Crypto APIs.
How to Get Started
Getting started with Svellora takes less than ten seconds:
- Visit svellora-chat.vercel.app from any modern web browser
- Enter any display name you prefer — it does not need to be your real name
- Click "Create New Room" to generate a new private room with a unique code
- Share the room code with the person you want to chat with
- Your partner enters the code on Svellora and clicks "Join Room"
- End-to-end encryption activates automatically — start your private conversation
That is it. No verification emails, no CAPTCHA challenges, no terms of service to scroll through. Just a private room for two people to talk.
Security and Privacy
Svellora's security architecture is built on several core principles:
- Zero-knowledge design — The server facilitates connections but cannot access message content
- Browser-native cryptography — All encryption uses the Web Crypto API (ECDH + AES-GCM)
- No persistent storage — No databases, no message logs, no user records
- Ephemeral keys — New encryption keys are generated for every session and destroyed when the session ends
- No tracking — No cookies, no fingerprinting, no behavioral analytics
- Minimal metadata — The server processes only what is needed for real-time message relay
Every design decision in Svellora prioritizes user privacy. We cannot read your messages, we do not store your messages, and we have no way to recover them after a session ends.
Frequently Asked Questions
Is Svellora really free to use?
Yes, Svellora is completely free. There are no hidden costs, premium tiers, or in-app purchases. Simply visit the website, create or join a room, and start chatting.
Do I need to create an account?
No. Svellora requires zero signup. You do not need an email address, phone number, or any personal information. Just pick a display name, create a room, and share the code with your chat partner.
How does the encryption work?
Svellora uses browser-native Web Crypto API to generate ECDH key pairs directly in your browser. When two users join a room, their browsers exchange public keys and derive a shared secret. All messages are encrypted locally before transmission using AES-GCM, so the server only ever sees encrypted ciphertext.
Are my messages stored on any server?
No. Svellora does not use any database. Messages exist only in active browser memory and are relayed in real time. The moment both participants close their tabs, the chat room and all its contents are permanently destroyed.
How many people can join a room?
Each Svellora room supports exactly two participants for intimate, focused 1-on-1 conversations. This design ensures maximum privacy and the strongest possible end-to-end encryption.
What browsers does Svellora support?
Svellora works on all modern browsers that support the Web Crypto API, including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Brave. Both desktop and mobile browsers are fully supported.
