ComfyUI-KittenTTS and ComfyUI-ChatterboxTTS
Both tools offer different text-to-speech (TTS) models as ComfyUI custom nodes: KittenTTS is an ultra-lightweight, CPU/CUDA compatible model, while ChatterboxTTS is described as a production-grade, open-source model; therefore, they are competitors offering distinct TTS capabilities for ComfyUI workflows.
