Choose Kokoro-FastAPI if…
- License: Kokoro-FastAPI is Apache-2.0, chatterbox-tts-api is AGPL-3.0.
- 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: fastapi, 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.
Choose chatterbox-tts-api if…
- License: chatterbox-tts-api is AGPL-3.0, Kokoro-FastAPI is Apache-2.0.
- Requirements: Requires a local setup environment that supports CUDA for optimal performance; Docker can simplify deployment..
- Tags unique to chatterbox-tts-api: ai, chatgpt, chatterbox, cuda.
- When you need a self-hosted solution that mirrors the functionality of ElevenLabs or other proprietary TTS services and requires compatibility with existing ecosystems like Open WebUI or AnythingLLM.
When NOT to use chatterbox-tts-api
- If you require integrations specific to ElevenLabs' proprietary voice models as Chatterbox-TTS-API, despite its capabilities, does not directly support their unique voice libraries.
- For users needing a fully managed service without the complexities of local deployment and maintenance, like that offered by cloud-based TTS providers.
