Open WebUI and AnythingLLM are two self-hosted interfaces for language models that answer questions about documents, run agents and address local as well as external models. They target different forms of use: Open WebUI the central server operation for many users, AnythingLLM getting started with a desktop app and small teams on a Docker instance.

This article compares both by the criteria that matter in operation: license, deployment form, sign-in and permissions, knowledge base, models and agents, telemetry, security advisories and cost. The information comes from the GitHub API, license files and vendor documentation as of 21 October 2026.

Short answer

Rule of thumb: Open WebUI for a central platform with many users, SSO, groups and knowledge bases. AnythingLLM for getting started with the desktop app, small teams without a connection to identity management, and free branding under MIT (Docker version).

Brief overview of both tools

Open WebUI (formerly Ollama WebUI) is a self-hosted web interface that originally emerged for connecting to Ollama and now also addresses OpenAI-compatible servers and other providers. Features and deployment options are described on the page Open WebUI at WZ-IT. How Open WebUI can be connected to Nextcloud with file permissions is shown in the article Connecting Open WebUI to Nextcloud: RAG with ACLs.

AnythingLLM describes itself as an all-in-one application for chat with documents, agents and RAG, as a desktop app and as a Docker server. The page AnythingLLM at WZ-IT describes installation and operation.

Basic data at a glance

License and branding

AnythingLLM is under the MIT license. The file has 20 lines and contains no branding requirement and no user limit; the repository has no ee or enterprise directory. The terms for self-hosted operation describe only the core as MIT and provide for service levels for self-hosted operation only through a separate enterprise agreement. The desktop subscription AnythingLLM Pro (lifts daily limits of the Magic features) and the hosted cloud are paid. The desktop app is governed by its own terms of use (as of 14 July 2025): use for personal and internal business purposes, no redistribution, no derivatives, no SaaS.

Open WebUI has been under the Open WebUI License since version 0.6.6: BSD-3-Clause plus clause 4. The clause prohibits changing, removing, obscuring or replacing the "Open WebUI" branding. Exempt are at most 50 end users within any rolling 30-day period, prior written permission from the rights holder or a signed enterprise license. With unchanged branding, commercial use is also permitted according to the license page, with no cap for internal deployments. White-label and co-branding require an enterprise license. The Terminals service for Open Terminal is in a separate repository under the Open WebUI Enterprise License.

The license history of Open WebUI: MIT up to version 0.5.4, BSD-3-Clause for 0.5.5 to 0.6.5, and the Open WebUI License from 0.6.6 (release of 5 May 2025); the code up to and including 0.6.5 remains under BSD-3-Clause. License history, the 50-user threshold and the enterprise license are explained in the article Open WebUI License and Branding.

Operation: server, desktop and architecture

The multi-user mode of AnythingLLM is available only in the Docker version and cannot be undone after it is switched on. AVX2 is a requirement on x86 hosts because of LanceDB; with another vector database it does not apply. The Helm chart in the repository carries appVersion 1.85.0 and therefore does not match version 1.18.0. For Open WebUI, the default vector database ChromaDB is not suitable for multiple workers or replicas according to the scaling documentation.

Sign-in, SSO and permissions

According to the docs, the Manager role in AnythingLLM manages everything except the settings for LLM, embedder and vector database; in the code, event logs, API keys, agent and MCP configuration, embed widgets and further system settings are additionally reserved for admins. For the Enterprise cloud tier, the vendor lists "SSO, RBAC, and more" without details. In Open WebUI, the documentation does not label any of the sign-in methods as an enterprise feature; the README lists LDAP, SSO and SCIM under "Enterprise Authentication & Provisioning".

Knowledge base and RAG

AnythingLLM assigns documents to a workspace; whoever sees the workspace sees all embedded documents. For sources with file permissions, the permission check belongs before the vector search, see Connecting Open WebUI to Nextcloud.

Models, agents and MCP

The plugin ecosystems are built differently: Open WebUI is extended on the server with Python, AnythingLLM is extended through MCP, Agent Flows and custom JavaScript skills.

Telemetry and data flow

Security advisories of the last twelve months

Published GitHub security advisories from 21 Oct 2025 to 21 Oct 2026:

The number says nothing about the quality of a project. It shows how much was reported and published. For both: apply updates promptly and do not expose the instance to the internet without sign-in. The AnythingLLM security policy excludes, among others, SSRF via web scraper and collector against internal hosts, SSRF via service URLs configured by the administrator, reports about agent tools enabled by the administrator and reports without password protection or multi-user mode as valid reports.

Vendor, support and cost

The AnythingLLM cloud instance runs isolated per customer, has no built-in model and supports neither MCP nor custom agents. Vendor prices: as of 21 October 2026.

Which tool for which use

AnythingLLM alternatives

AnythingLLM reaches its limits for teams in three places: sign-in and permissions (local accounts, three fixed roles, no groups; OIDC, LDAP, SAML and SCIM are not described in the docs), sources with document permissions (no permission sync) and operating several instances (the docs advise against horizontal scaling with SQLite). Depending on the case, these alternatives come into question:

The detailed comparisons: Open WebUI vs LibreChat, LibreChat vs AnythingLLM and Open WebUI vs Onyx. All six platforms are in the overview Open WebUI alternatives.

Combining both

In some environments both run in parallel: Open WebUI as the central platform for many users, AnythingLLM Desktop as a single-seat tool for analyses on the laptop. Both address the same model servers, for example Ollama or vLLM, and therefore share the GPU resources. Credentials and documents stay separate.

Should Open WebUI answer questions about your own documents, with sources and per-person permissions?

GDPR and data protection

With self-hosting, accounts, chats and documents stay in your own infrastructure, in a data center in the EU or in Germany. Whether prompts and document excerpts leave the premises is decided by the choice of models: local models via Ollama or vLLM and models at providers in Germany keep the data path in the country, connections to US providers send prompts there. In addition there are the outbound connections from the section Telemetry and data flow, which can be switched off or limited by firewall. On professional secrecy and Section 203 of the German Criminal Code (StGB), see the overview AI platforms for businesses compared; this article is not legal advice.

Common misconceptions

• "Open WebUI is MIT-licensed." No. Since version 0.6.6 the Open WebUI License with a branding clause applies; only AnythingLLM is under MIT (repository and Docker version; the desktop app has its own terms of use).
• "AnythingLLM is only a desktop app." No. There is a Docker version with multi-user operation, roles and invitations.
• "AnythingLLM offers SSO via OIDC or LDAP." Not in the documentation. There are local accounts and Simple SSO Passthrough, in which an upstream system generates login links.
• "Open WebUI needs Ollama." No, Open WebUI also talks to OpenAI-compatible servers, and Ollama is optional.
• "Self-hosted means no outbound connection." AnythingLLM sends telemetry to PostHog and downloads models from a CDN, Open WebUI checks for updates. Both can be switched off.
• "Both take over file permissions from the source systems." No. AnythingLLM has no permission sync, and for Open WebUI it is not documented.

Data and methodology

As of: 21 October 2026. The data basis is the GitHub API (license, version, stars, published security advisories), the LICENSE files of the repositories, the documentation of Open WebUI and AnythingLLM, and the AnythingLLM pricing page. Stars are rounded and change daily. Statements with "not described in the docs" mean that the documentation does not describe the feature; the function may exist in the code. The connector list of AnythingLLM comes from the source code, not from an official list. The advisories cover the period from 21 October 2025 to 21 October 2026.

How WZ-IT works

WZ-IT runs Open WebUI as an AI platform: your own instance with models operated in Germany by German providers, SSO and a Section 203 supplementary agreement, from EUR 149.90 net per month. The Open WebUI branding stays visible, WZ-IT does not present Open WebUI as its own product; we clarify license questions such as the branding clause before rollout. WZ-IT runs AnythingLLM as managed hosting in German data centers, with a data processing agreement. We also install both platforms in your infrastructure, for example on Hetzner or Proxmox, and connect sign-in to Keycloak or Authentik (LDAP, SAML, OAuth). Monitoring runs with Uptime Kuma and Grafana.
