Choose dia if…
- Tags unique to dia: dialogue-generation, tts.
- When you require precise control over voice and script in the creation of highly realistic dialogues
- More GitHub stars (19k vs 5.5k) - visibility, not fit.
When NOT to use dia
- If your setup lacks a GPU, as Dia has not yet added CPU support
- In scenarios where immediate real-time performance is critical since the first run could be longer due to additional codec downloads
Choose Kokoro-FastAPI if…
- 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, fastapi, kokoro tts, multi-gpu support.
- 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.
