Chatterbox TTS vs Real-ESRGAN
Both stand on image upscaling software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Open source APILinuxMac+2
Chatterbox offers several open-source model choices, with documented installation paths and device options. Generated files carry a PerTh watermark, and Resemble says its voice generation is no longer a commercial product.
