| API | The App development workflow starts a local API on port 8000 alongside a web UI on port 3000, and the Python app can mount a FastAPI realtime API. | The backend exposes HTTP endpoints for health, models, presets, conversion, and updates, plus a WebSocket endpoint for real-time audio. |
| Integrations | Official download materials link Google Colab, Pinokio and Hugging Face as cloud or one-click launch options. | The README documents ONNX Runtime, PyTorch, RVC, and GitHub Releases for updates; it does not list third-party conferencing integrations. |
| License | The source code and model weights are released under the permissive MIT license, including modification, redistribution and commercial use subject to the project terms. | The repository is distributed under the MIT License. |
| Platforms | The download page lists desktop apps for Windows 10/11, macOS 12+ on Apple Silicon or Intel, and Linux, plus a Gradio WebUI. | The README documents Windows setup and says other platforms use manual setup; its Makefile supports POSIX shells or WSL. |
| Product | Applio is an open-source AI voice conversion suite for creating covers, training custom voice models, and converting voices in real time. | OpenVoiceChanger is a self-hosted web application for real-time AI voice conversion using ONNX or RVC models. |

In their own words
Applio
Applio is an open-source AI voice conversion suite for making covers, training custom voice models, and changing voices in real time. It can convert recorded audio with ready-made models, plus pitch tuning, cleanup, upscaling, and batch processing. Live conversion is intended for songs, streams, and calls. Model tools include training, a voice blender, text-to-speech, and an audio analyzer for dataset readiness. Applio supports Linux, macOS, Windows, web, and self-hosted use; Google Colab, Pinokio, and Hugging Face are also listed as ways to run it. Its plan is free, with no accounts or paywalls. The MIT license permits personal, research, and commercial use. The maker says audio and models remain on the device unless shared, and core features do not require an account, telemetry, or cloud dependency. Documentation recommends an Nvidia RTX 20-series GPU or newer for local voice training; most modern computers can handle inference with existing models.
