Crystal-clear P2P voice

Everything you actually use
Full-featured. Still weighs nothing.
Not a stripped-down toy — the stuff you reach for on a raid night, minus the bloat, the ads, and the launcher that eats a gigabyte before you say a word.
Push-to-talk
Hold to speak, release for silence. No open-mic keyboard clatter, no breathing into the void mid-clutch.
Global mute & deafen
Cut your mic or drop all incoming audio without alt-tabbing. The hotkeys fire even when LightVC isn't the focused window.

Text chat with history
Drop links, callouts, and coordinates in the room. Messages stick around, so whoever joins late can scroll back and catch up.
Image & file sharing
Paste a screenshot of that impossible boss, or send a config straight into chat — up to 50 MB a file. Thumbnails show inline; click to open full-size.
Screen sharing
Show your run, your build, or the bug you swear isn't your fault. One click opens a share right in your browser, tied to the same room.
Where the megabytes went (nowhere)
Native code. Your audio never touches a server.
LightVC is written in Go and draws its own window — no Chromium, no Electron, no 300 MB of browser stuffed inside a chat app. That's why it starts instantly and sips memory.
- Peer-to-peer & encrypted. Voice runs directly between friends over SRTP. The signaling server only trades the handshake — it can't hear you.
- No account, no tracking. Your group joins with one shared invite secret. That's the whole login — nothing to sign up for.
- Runs on a potato. Old laptop, budget build, streaming rig already maxed — LightVC leaves the headroom for the game.
