End-to-end encrypted
Audio and messages are encrypted on your device and only decrypted at the recipient. Your keys never leave your devices.
Peer-to-peer · End-to-end encrypted
Nexyn connects you directly — device to device. No central server stores your conversations, because none ever gets to see them.
Open beta · free · Windows & Linux
Live
This many people are currently connected to the Nexyn network — live, straight from the relay.

A quick look — decentralized, encrypted, yours.
What sets Nexyn apart
Most voice apps route everything through their servers. Nexyn flips that around: the technology is built so that eavesdropping isn’t even possible.
Audio and messages are encrypted on your device and only decrypted at the recipient. Your keys never leave your devices.
Your audio travels via WebRTC straight to the other side instead of through a mixing server — less latency and no central point that could listen in.
The signaling server only brokers the connection setup. It never gets to see content, keys or conversation data.
If the current host leaves, another device takes over automatically — no central authority, no downtime for everyone else.
Real-time noise suppression filters keyboard, fans and background noise right on the device — without the detour through a cloud.
Themes, custom color schemes, avatars, push-to-talk or voice activation. Nexyn adapts to you — not the other way around.
A closer look
One tidy window for everything — no nested menus, no learning curve.
Voice and text channels, the online list and jumping into a conversation — all in a single window. One click on a voice channel connects you instantly, with no call ceremony.
Every voice channel has its text channels right beside it. Shared links turn into clean preview cards with title, description and image — sharing explains itself.
Up to 48 kHz, plus noise and echo suppression, a noise gate, automatic gain and an AI noise filter (RNNoise) — all on-device and each toggle on its own.
Ready-made themes like Nexyn, Midnight Purple, Ember or Matrix — or build your own color scheme, export it as a file and share it with others.
Pick from colorful avatar presets — others see it in the voice HUD, in channels and in chat. And the interface comes in five languages: German, English, Spanish, French, Russian.
One-to-one chats are end-to-end encrypted straight between you, with read receipts. And before you trust someone, you compare their device fingerprint and safety number (Signal-style) — so “verified” really means verified.
Roles with fine-grained permissions, tiered verification, invite links with QR code, expiry and usage limits, a dedicated ban overview — and a tamper-evident moderation log that can’t be quietly rewritten after the fact.
How it works
Three steps, one principle: brokering and content are strictly separated. Whoever connects you doesn’t listen in.
Two clients exchange only the technical info they need to find each other, via the zero-knowledge relay — encrypted.
Once the handshake is done, WebRTC connects the devices directly. From that moment the relay is out of the loop.
Audio and chat flow end-to-end encrypted directly between you. No one in between can listen — not even us.
How it compares
An honest comparison with Discord and TeamSpeak — on what we care about: privacy, control, no lock-in.

FAQ
Answered briefly and honestly.
During the open beta, Nexyn is free — just download and use it.
Windows 10 and 11 as well as Linux (as an AppImage). Both get automatic updates.
Yes. Audio and messages are encrypted with libsodium on your device and only decrypted at the recipient — your keys never leave your devices.
No. The relay is zero-knowledge and only brokers the connection setup. Audio then flows directly between participants (P2P) — the server never gets to see any content.
No, no sign-up is required to get started — download, launch, connect.
No. Nexyn is peer-to-peer — there’s no server to rent or run. One device hosts the session, and if it leaves, another takes over automatically.
Get started
Download Nexyn, launch it, connect. Updates arrive automatically.
