LM Studio vs Open WebUI

LM Studio

• Running open models privately on a Mac, Windows or Linux computer
• Developers who want a local OpenAI-like endpoint for their own tools
• Agent work on code and documents with open models, through Bionic

Open WebUI

• Teams that want a chat interface running on their own infrastructure
• Using local models from Ollama through a browser interface
• Organizations that need SSO, roles and on-premises or air-gapped deployment

LM Studio

• LM Studio itself is desktop only; on iPhone and iPad its models are reached through the separate Locally app. Intel-based Macs are not supported.
• Local models need capable hardware: the docs recommend 16GB of RAM or more, and on Windows at least 4GB of dedicated VRAM.
• The paid plans cover cloud models in LM Studio Bionic, a separate app; cloud use needs an LM Studio account with available credits.
• LM Link is in preview and free for now; LM Studio says free and paid LM Link plans will follow at general availability.

Open WebUI

• There is no hosted service: you install and run it yourself with Docker, pip or Kubernetes, and supply your own models or provider API keys.
• Since v0.6.6 the license is not OSI-approved open source: deployments with more than 50 users must keep the Open WebUI branding unless they hold an enterprise license.
• The desktop app for macOS, Windows and Linux is labeled early alpha, and the docs point production deployments to Docker or Python.
• Enterprise license prices are not published, and licenses are sold only to registered organizations, not individuals.

LM Studio

Local model runner

Downloads and runs open models such as gpt-oss, Qwen, Gemma and DeepSeek on your own hardware with llama.cpp, plus Apple's MLX on Apple Silicon Macs.

Offline chat with documents

Chat and document chat (RAG) run on the device. The docs say nothing entered into a local chat or dropped into it as a document leaves the machine.

Local API server and SDKs

Serves models on OpenAI-like endpoints on localhost or the local network, with Python and TypeScript SDKs, the lms command line tool and the headless llmster daemon for servers.

MCP client

MCP servers can be installed in LM Studio so that local models can call the tools they provide.

LM Link

Links your own machines over an end-to-end encrypted connection built on Tailscale, so a model on a remote device can be used as if local, including from an iPhone through the Locally app. In preview.

LM Studio Bionic agent

A separate app that works on code and on documents, slides and spreadsheets inside projects, using local models, LM Link models or cloud models billed in credits.

Open WebUI

Any model in one interface

Chats with Ollama, OpenAI, Anthropic or any OpenAI-compatible provider. You can switch models mid-conversation or run two side by side to compare their answers.

Knowledge bases and RAG

Upload files and build knowledge bases searched with hybrid BM25 and vector search, or inject whole documents. The docs list 13 vector databases and 8 extraction engines.

Web search and code execution

Models can search the web and cite sources, and run Python in the browser or through Open Terminal, which gives the model a real terminal and filesystem to work in.

Tools, functions and MCP

Extend it with Python tools and pipelines, MCP servers and OpenAPI endpoints, or install prompts, models, tools and functions shared by the community.

Multi-user access control

Roles, groups and per-model permissions, with SSO through OIDC or LDAP, SCIM 2.0 provisioning and API keys for programmatic access.

Channels and notes

Channels are shared spaces where teammates and @-tagged models post in one timeline. Notes is an editor whose pages can be attached to a chat as context.
