Like Discord. Without the lag, ads, or bloat.
Real-time voice and chat for gamers, teams and communities, built native on a Rust core.
Built for real conversations.
Servers, channels, voice rooms and direct messages in one native app.
The problem
If your voice app is fighting you, switch.
Most communication tools were built for everything except real conversation. Three things people put up with that they should not have to.
Voice lag costs you the round.
Your callouts arrive after the gunfight and your reactions land a step late. Voice should be instant, not an echo of what already happened.
Your chat app should not eat 560 MB of RAM.
Most chat apps run a hidden browser engine. We measured Discord at about 560 MB idle. You pay for it in frames, fan noise and battery for every minute the app is open.
Your DMs are not actually private.
On most chat apps the server can read every message you send. Mods, admins, operators, advertisers: somebody is in the loop. Private should mean private.
What we built
Four decisions that shape the app.
Each one with the figure or the standard behind it. The details live on the feature pages.
- Low-latency voiceVoice over QUIC with frames down to 5 ms on the Low Latency preset, jitter buffering and packet-loss recovery.QUIC
- Private by defaultVoice is keyed by MLS 1.0 on a hybrid post-quantum ciphersuite. Direct messages use HPKE with hybrid X25519 + ML-KEM-768. Server channels run over encrypted transport.MLS, PQ hybrid
- Featherweight clientA Flutter interface on a Rust core for Windows, macOS, Linux and Android, and iOS via TestFlight. No Electron, no hidden browser engine, a fraction of the memory.Native
- Built for reliabilityAutomatic reconnection and connection migration keep you connected. QUIC handles a switch from Wi-Fi to mobile without dropping the call.Always connected
Voice, privacy and memory, measured
Voice that arrives on time.
Voice over QUIC. Frames down to 5 ms on the Low Latency preset, with jitter buffering and packet-loss recovery.
- Encrypted delivery over QUIC, no head-of-line blocking
- 48 kHz audio
- Large rooms without losing quality
Your conversations. Your data. Always.
Direct messages and voice calls are end-to-end encrypted, so the server never sees your messages or hears your calls. Voice runs on MLS 1.0 (RFC 9420): every frame is authenticated under an MLS-derived key, and keys rotate on every join and leave. Server channels are protected with transport encryption.
- E2E encrypted DMs and voice, keys never leave your device
- MLS voice: every frame authenticated, forward secrecy on join and leave
- No data harvesting, no ad targeting, no selling your info
- Account data hosted in the EU, voice E2E encrypted across every region

Read the methodologyBuilt for
Whatever you are here for, we built for it.
One app, three groups it was made for. Pick the one that sounds like you.
Competitive gamers
Win the round, not the lag
- 5 ms voice frames on the Low Latency preset
- Packet-loss recovery built into QUIC
- Native client with no browser engine underneath
Communities
Run your space, your way
- Servers, channels, roles, custom emoji
- Moderation tools with a role hierarchy
- Public discovery and invite links with limits
Teams and developers
Talk privately, anywhere
- E2E encrypted DMs and voice by default
- EU-hosted account data, a growing voice network
- File sharing and full-text search
- Frame size on the Low Latency preset; other presets use larger frames. Measured end-to-end latency depends on your route to the region.
- Idle memory, measured 2026-04-26 on Windows 11 with the friends list open, conservative end of five runs. Method and all runs: measurement methodology.
- Region list is deployment configuration, last confirmed 2026-06-14 and updated with each release. It is not a live status feed. Account data is hosted in the EU; voice is end-to-end encrypted on every region.
