Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
内置 RAG 与智能体的 AI 原生 Postgres 后端
每个项目都运行独立隔离的 PostgreSQL 实例,具备行级安全,并配备托管认证、对象存储与实时订阅——没有共享逻辑数据库,也就没有嘈杂邻居风险。
上传 PDF、图片、Office 文件或网址,Powabase 会自动提取、切块、向量化并建立索引。支持 BM25、pgvector、混合检索、多模态索引与重排序模型。
用多个 LLM、知识库和工具定义 ReAct 风格的智能体。运行结果通过 SSE 流式返回,会话保存在你项目的 Postgres 中,敏感工具调用可加入人工审批。
拖拽并连接触发器、条件、智能体、HTTP 调用、代码等积木,组装多步骤工作流,也可让自然语言副驾驶代为设计流程。部署后即可变为 HTTP 端点。

免费 / 开源Focuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
专项更强强烈专注于注重隐私的文件聊天与本地 RAG 管道,但提供较少的通用聊天 UI 功能。

免费 / 开源Mastra is an open-source TypeScript framework for building, deploying, and observing AI agents and workflows. It gives JavaScript developers typed agents, durable workflows, memory, MCP tool support, and built-in observability so prototypes can scale into production.
