Open-source LLM chat frontend for power users with character cards, lorebooks, extensions, and support for many model backends.
SillyTavern is a free, open-source frontend for interacting with LLM backends, popular for character chat and long-form roleplay. It provides a rich chat UI with character cards, prompt controls, and an extensions ecosystem. Core features include “World Info” (lorebooks/memory books) for dynamically injecting context into prompts and STscript/Quick Replies for automation-like macros and scripted actions. SillyTavern is licensed under AGPL-3.0 and is typically self-hosted or run locally, connecting to external model providers or local inference stacks rather than running models itself.
