Chats

Chats, published as Sdcb Chats, is an open source large model front end and AI gateway written in C# and TypeScript by .NET developer Zhou Jie. Organisations deploy it on their own infrastructure, connect it to more than 22 model providers, and give staff one chat interface while keeping their data in house. Supported providers include Azure AI Foundry, OpenAI, Anthropic, Google, DeepSeek, OpenRouter, Ollama, x.ai, GitHub Models and many Chinese platforms such as Alibaba Bailian, Tencent Hunyuan, Baidu Qianfan and Zhipu. It is aimed at companies and technical teams that want private deployment with central control. The gateway speaks the Chat Completions, Anthropic Messages, Responses and Gemini protocols, so tools such as Claude Code can connect through it. A Docker sandboxed code interpreter adds a browser, code execution and Excel tooling. Request Trace follows inbound and outbound calls for debugging. Storage options cover SQLite, SQL Server and PostgreSQL, with files on local disk, S3, Alibaba OSS or Azure Blob. Administration includes permissions, balance controls, rate limiting and auditing, Keycloak single sign on and SMS code login, and it handles vision input and image generation. The software is free under the Apache License 2.0. It installs with one Docker command or as native executables for eight Windows, Linux and macOS platforms. There is no paid tier or hosted plan; costs are the underlying model providers and the user's own hosting. Version 1.17 shipped in August 2026, and a published 2.0 roadmap shifts the focus to agents, with persistent Docker workspaces, publishing sites to a subdomain, and agents that ask clarifying questions. The main site is in Chinese with an English version available.
