Open WebUI

Open WebUI is a self-hosted chat interface that puts local models served by Ollama or llama.cpp and hosted model APIs behind one web app, with user accounts, knowledge and RAG, tools and MCP, SSO, LDAP, RBAC, and SCIM. It is free to use as-is under its own license, which keeps the branding above 50 users; enterprise licenses add white-labeling and support.

The 30-Second Take

Pick Open WebUI if chats and documents must stay on your own servers and staff want any model in one interface.

It puts local models and hosted APIs behind one web app, with SSO, SCIM and an audit log, free to use as-is. Above 50 users its license keeps the Open WebUI branding without an enterprise license.

Best fit
IT and platform teams that must keep chat data in their own infrastructure and want local and hosted models in one assistant.
Main constraint
Your team hosts, secures, and upgrades it, and the branding stays above 50 users without an enterprise license.
First move
Run it on Postgres with SSO and the audit log on for one team, and test each upgrade on a staging copy first.

Why

Watch the upgrades: practitioners report regressions, and one multi-replica deployment rolled v0.12.0 back after memory grew to 8 to 11 GB. The audit log is off by default, and your team hosts and patches it.

Comparisons

How does Open WebUI compare with the alternatives?

  1. Open WebUI vs ChatGPT

    • AI Assistants

    Run Open WebUI when chats must stay on your servers and you want any model in one interface. Buy ChatGPT Business or Enterprise when you would rather pay per seat than host and patch an assistant.

  2. Open WebUI vs Claude

    • AI Assistants

    Run Open WebUI to host any model, Claude included, on your own infrastructure. Buy Claude Team or Enterprise when Anthropic's assistant, its apps, and its admin controls matter more than running the interface yourself.

What business and product leaders should verify before rolling it out across teams.

Sourced from Open WebUI documentation

How you buy it

Free to use as-is

Free under its own license; enterprise licenses are quoted from the expected end-user count.

Source 1, Open WebUI, Enterprise: EnterpriseSource 4, Open WebUI, License: License

Details

Open WebUI is free to use as-is, with no enterprise agreement, under its own license: BSD-3 with a branding clause since v0.6.6. Enterprise licenses add white-labeling, rebranding, enterprise-only features such as Terminals, and dedicated support, quoted from the expected end-user count. Open WebUI publishes no license price.

Cost drivers

Your servers and keys

You run the app, its database, and Redis; model makers bill tokens on your keys.

Source 1, Open WebUI, Enterprise: EnterpriseSource 4, Open WebUI, License: License

Details

Your servers and your models drive cost: you run the app, its database, and Redis once there is more than one replica, and each model maker bills its tokens on your keys, or local models run on your hardware. The branding must stay unless a deployment has 50 or fewer users in a rolling 30-day period, written permission, or an enterprise license. Open WebUI publishes no usage metering or overage terms.

Where it runs

Your infrastructure

On-premise, private cloud, hybrid, or air-gapped; you own the database and its retention.

Source 1, Open WebUI, Enterprise: EnterpriseSource 2, Open WebUI, Enterprise security: Enterprise security

Details

On your infrastructure: on-premise, in a private cloud, hybrid, or air-gapped, from Python on VMs, managed containers, or Kubernetes with Helm. Data stays in your infrastructure unless you connect external model APIs, and you own the database and its retention policies.

What to verify

Audit log off by default

The request audit log stays at AUDIT_LOG_LEVEL=NONE until you set it.

Source 2, Open WebUI, Enterprise security: Enterprise securitySource 3, Open WebUI, Environment configuration: Environment configuration

Details

SSO through OIDC and OAuth 2.0, LDAP and Active Directory, and RBAC are built in, and SCIM 2.0 is included in the free edition. The request audit log is off by default (AUDIT_LOG_LEVEL=NONE) until you set it. Compliance certifications such as SOC 2 apply to your own deployment, and the software itself carries none. DEFAULT_MODELS pre-selects a set of models on a new chat, and a user's own default model takes precedence.

Signals

What is the current evidence saying about Open WebUI?

A current read of what people running Open WebUI for themselves, their teams, and their companies report publicly, with each finding linked to its sources.

How this figure is made

Current sentiment

Positive, mixed and negative sources

Teams running Open WebUI for an organization mostly report problems: upgrade regressions are raised in 8 sources, feature gaps in 14, and performance at scale in 7, from KION GROUP's 40,000-user deployment to a three-replica rollback from v0.12.0. 2 of the 4 who describe a choice of chat interface kept Open WebUI.

Run a pilot on your team's recurring tasks to measure how often answers are used without rework.

FootprintOpen WebUI across the AI Knowledge Work stack. Bar height is its role on each layer.

  1. Assist

    1. AI assistant: Core

      AI assistant, core. General assistance is Open WebUI's primary role: a web chat with history, search, per-model prompts, and agents with bound tools and knowledge, on whichever models the team connects.

  2. Find

    1. Web research: Supports

      Web research, supports. Built-in tools and web search integrations, such as a self-hosted SearXNG, let models look things up during a chat. A dedicated answer engine still owns cited research workflows.

    2. Enterprise search: Supports

      Enterprise search, supports. Knowledge and RAG over uploaded documents support 13 vector databases and 8 extraction engines with hybrid search, governed by group permissions. Search across every company app stays with an enterprise search product.

  3. Create

    1. Documents: Touches

      Documents, touches. Chats and Notes draft text, while the team's documents and wiki stay in its own workspace tools.

    2. Meeting notes: Touches

      Meeting notes, touches. Open WebUI documents no meeting capture: it works on chats, notes, and documents, and recording meetings stays with a meeting notes product.

  4. Analyze

    1. Data analysis: Touches

      Data analysis, touches. Open Terminal provides a sandboxed environment for code execution in chats, while governed analytics on the company's data stays with an analytics tool.

  5. Automate

    1. Automation: Supports

      Automation, supports. Built-in tools, MCP servers, sub-agents, timers, and automations let models act on their own. Deterministic automation across many apps runs in a workflow automation product such as n8n.
