It offers a web interface and command-line inference capabilities; pick Dot if local, JavaScript-based all-in-one solution for Text-To-Speech, RAG models, and working with LLMs. [ChatTTS](https://2noise.com) reports 40k GitHub stars, 4.3k forks, and 60 open issues, last pushed Apr 10, 2026. [Dot](https://dotapp.uk/) has 1.9k stars, 109 forks, and 14 open issues, last pushed Dec 9, 2024.
