SillyTavern is a free, open-source (AGPL-3.0), locally-installed/self-hosted web frontend for interacting with large language models, originally forked from TavernAI in 2023 and now a large community project. It provides a single unified interface for both cloud and local LLM backends and is heavily used for character-based chat and roleplay, with advanced features like character cards, world info/lorebooks, group chats, prompt/preset management, extensions, and optional image generation and TTS. It hosts no AI service itself and tracks no user data, so users bring their own API keys (or run fully local models). Under Chat Completion mode users pick a source (OpenAI, Claude/Anthropic, Google AI Studio/Vertex, OpenRouter, Mistral, DeepSeek, Cohere, Perplexity, xAI Grok, Groq, Fireworks, AI21, etc.) and paste their own key, or choose "Custom (OpenAI-compatible)" to set an arbitrary base URL plus key for services like LM Studio, LiteLLM, LocalAI, and Ollama. Actively maintained with frequent releases (v1.18.0 in May 2026).

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
