Luker

Luker is an open-source LLM frontend forked from SillyTavern, aimed at power users who prioritize performance, customizability, and API clarity.

It improves on the original with a cleaner API design and stronger extension capabilities. Patch-first persistence (chat append/patch, metadata/state patch, and settings patch) avoids repeated full‑save payloads, greatly improving storage efficiency. The backend owns the generation lifecycle, including reconnect‑safe persistence, making interactions more stable.

Advantages include high extensibility, efficient persistence, and suitability for further development or deep customization. However, as an early‑stage project, it may have limited documentation and community support. Regular users might need extra time to learn the configuration. As an open‑source tool, it is free to deploy on your own infrastructure, but requires some technical skill such as command‑line usage and editing configuration files.

Luker is designed for power users and developers who enjoy tweaking their LLM frontend. It is not ideal for those seeking a plug‑and‑play chat experience without any setup hassle.
