Jamie Pine — the dev behind Spacedrive — built Voicebox, and it added 629 stars in a single day on its way to 43K. It’s an open-source desktop voice studio (Tauri Rust shell + React + FastAPI sidecar) that kills two subscriptions at once: ElevenLabs for voice generation, WisprFlow for dictation. Everything runs on your machine. No cloud, no per-character billing, MIT license.
What it does
Clone a voice from a few seconds of audio. Generate speech in 23 languages across 7 TTS engines — Qwen3-TTS, Chatterbox, Kokoro and more. Press a global hotkey and dictate into any text field on your Mac or PC. A bundled local LLM polishes your words and keeps per-profile personas.
The MCP server is the real story
Voicebox ships a built-in MCP server, so any MCP-aware agent — Claude Code, Cursor, Cline — can speak in your cloned voice, transcribe audio, and browse voice profiles. Your coding agent announcing a failed build in your own voice is one config file away.
Voice and agents are the two hottest threads in AI right now. Voicebox sits exactly at the knot — that’s why it’s trending.
