Choose Chatterbox-TTS-Server if…
- License: Chatterbox-TTS-Server is MIT, Kokoro-FastAPI is Apache-2.0.
- Requirements: Python 3.10 needed for pre-built wheels; avoid Python >=3.11 due to lack of support.; Ensure hardware and driver meets the Hardware Compatibility Matrix requirements..
- Tags unique to Chatterbox-TTS-Server: ai, api-server, audio-generation, chatterbox.
- Chatterbox-TTS-Server ships Docker support for self-hosted deployment.
- You need a self-hosted Text-to-Speech service that supports advanced features like voice cloning.
When NOT to use Chatterbox-TTS-Server
- When only pre-built wheels and no flexibility with Python versions is required (strictly follows Python 3.10).
- If your hardware or OS lacks support detailed in the compatibility matrix, like unsupported GPUs/CPU setups.
- For projects requiring minimal dependencies without manual handling of installation intricacies.
Choose Kokoro-FastAPI if…
- License: Kokoro-FastAPI is Apache-2.0, Chatterbox-TTS-Server is MIT.
- Requirements: Min 4 GB RAM; Requires Docker; Hardware-specific Docker images are provided for CUDA, ROCm (experimental), and CPU support.; Users without supported GPUs can still utilize the service via a CPU image..
- Tags unique to Kokoro-FastAPI: docker, kokoro tts, multi-gpu support, openai-compatible-api.
- You require a solution that can auto-download models and run natively on Apple Silicon (MPS) with support via UV.
When NOT to use Kokoro-FastAPI
- If your hardware is not supported by the provided Docker images, for example, if you do not have a compatible NVIDIA, AMD GPU or CPU setup.
- You are looking for non-Dockerized solutions. Kokoro-FastAPI focuses on containerization and might not fit environments that strictly avoid containers.
