SocketSVC

Proximity voice chat for Minecraft, carried over WebSockets instead of UDP. Players hear each other based on how close they are in-game, and there is no second port to punch through your firewall — voice rides the same kind of connection your browser already uses for HTTPS.

What to install

Every player needs the client mod. The server needs one of the server-side pieces.

	Install	Guide
Client	mods/ — Fabric, Quilt, NeoForge or Forge	Installation
Server (plugin)	plugins/ — Paper, Purpur or Folia	Server setup
Server (mod)	mods/ — Fabric, Quilt, NeoForge or Forge	Server setup
Proxy (optional)	plugins/ — Velocity, BungeeCord or Waterfall	Proxy relay

Fabric and Quilt need Fabric API. Mod Menu is optional.

You can also use voice in singleplayer — open a world to LAN and the client hosts the voice server itself. See LAN and singleplayer.

Why WebSocket instead of UDP

• Nothing extra to forward. The voice connection starts as an ordinary HTTP upgrade, so a reverse proxy, Cloudflare Tunnel, ngrok, or a Docker/Pterodactyl panel carries it with no extra configuration.
• Real wss:// encryption from the TLS termination you already run.
• One socket. Audio, the player roster, speaker snapshots and status updates all share a single connection.
• One public port for a whole network. The proxy relay fronts every backend, so per-backend voice ports stay internal.

Features

Voice

• Proximity audio with distance falloff and left/right panning
• Push-to-talk or voice activation, mute and deafen
• Per-player volume, so you can turn one person down without turning everyone down
• Opus audio with a jitter buffer and packet-loss concealment, plus automatic reconnect

Audio quality

• Noise suppression (RNNoise, with optional DeepFilterNet downloaded on demand)
• Echo cancellation, automatic gain and limiting
• Headphone spatial audio

More than talking

• Voice groups — named channels you join from the in-game menu
• Soundboard — play local clips to nearby players
• Instruments — MIDI keyboard, line-in, drum machine and loop station
• Head animation that follows the speaker's voice
• Custom icon packs, including animated ones

Quality of life

• A voice-chat badge next to servers in the multiplayer list, so you know before you join
• Works alongside Simple Voice Chat and Plasmo Voice — keep either installed, and each server gets the right one
• In-game updater that installs a new build on your next restart
• Available in 10 languages, following your Minecraft language setting

The Paper plugin and the proxy plugin are one jar each and work across all of the above. Builds marked beta are built against a beta loader release, not a beta of SocketSVC.

Getting started

1. Put the client jar in mods/, and the server jar in plugins/ or mods/.
2. Start the server once — it writes config.yml (Paper) or socketsvc-server.yml (server mod).
3. Set public-url to an address your players can reach, then /ssvc-server reload.

Everything else has a default that works on LAN. For a public server behind TLS, see Server configuration; for a network, see Proxy configuration.

Press V in game to open settings, B to talk, G for voice groups. Full list under Controls.

For developers

SocketSVC exposes a spatial speaker API so your own plugin or mod can place audio in the world — music, PA announcements, named in-world speakers.

• Spatial audio API
• API reference — client, Paper, server mod and proxy
• Voice protocol
