Voicebox

Free, local ElevenLabs alternative with voice cloning and a stories editor

Voicebox is an open-source desktop voice synthesis studio that runs entirely on your local machine — no subscriptions, no API keys, no data leaving your device. It bundles five TTS engines (Qwen3-TTS, LuxTTS, and Chatterbox variants) covering 23 languages, giving you ElevenLabs-grade capabilities at zero recurring cost. The standout features are voice cloning from audio samples in seconds, a multi-track Stories Editor for composing podcasts and dialogue scenes, eight post-processing audio effects (pitch shift, reverb, delay, compression), and smart auto-chunking that handles up to 50,000 characters with crossfaded seams. Built-in Whisper transcription rounds out the workflow. A full REST API means you can wire Voicebox into any downstream pipeline or custom integration. Technically it's a Tauri desktop shell (Rust) wrapping a React frontend and Python FastAPI backend. GPU acceleration supports Apple Silicon via MLX, NVIDIA via CUDA, AMD via ROCm, and Windows via DirectML. The MIT license and local-first architecture make it especially compelling for any use case where sending voice data to the cloud is a concern.

Panel Reviews

The Builder

Developer Perspective

Ship

“Five TTS engines under one roof, a full REST API, and Tauri + Python FastAPI architecture that's easy to extend. The auto-chunking to 50k characters and crossfading solve the real pain of long-form voice generation. This is the local voice stack I've been waiting for.”

The Skeptic

Reality Check

Skip

“Running five different TTS engines locally means significant disk and RAM footprints. Quality will still trail ElevenLabs' latest models for professional use cases. The stories editor sounds great in theory but multi-track voice timelines are notoriously fiddly — wait for v1.0 stability.”

The Futurist

Big Picture

Ship

“Voicebox signals the commoditization of ElevenLabs-quality voice synthesis. When creators can clone voices, build multi-character audio dramas, and deploy via REST API for zero per-character cost, the economics of audio content production change fundamentally. This is that inflection point.”

“The Stories Editor alone is worth it — composing multi-voice podcast conversations in a timeline without a cloud subscription is a dream. Voice cloning from samples, eight audio effects, and 23-language support make this my new go-to for any audio content work. It ships today.”
