Alternatives to Open WebUI
Self-hosted chat UI for local and API models
Open WebUI ranks #7 of 7 in Local LLM runners, with an Alt Score of 66. It is licensed under Open WebUI License (BSD-3-Clause-based with branding restriction), open source with paid hosting from Free and available on Linux, Windows, macOS and Web. 12 of 12 checklist rows are verified against a public source.
Individuals, teams, and enterprises who want a private, self-hosted chat interface for LLMs instead of relying on cloud AI providers, as well as developers who want to extend or customize their AI stack.
A ChatGPT-like web UI that connects to Ollama or any OpenAI-compatible API, with built-in RAG over your own documents, multi-user support with role-based access control, and the ability to run entirely offline. It also supports web search integration, image generation, voice/video calling, and a plugin system for custom tools and functions.
You deploy Open WebUI yourself (via Docker, pip, or Kubernetes), pointing it at one or more model backends such as Ollama or an OpenAI-compatible API. A FastAPI backend with a Svelte frontend handles chat, user accounts, and document retrieval, storing data in SQLite or PostgreSQL.
