Langdock vs Open WebUI

Langdock

• European companies rolling out AI to every employee under GDPR
• Organizations that want several model providers behind one admin console
• Teams building internal agents and automations on company tools

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

Langdock

• There is no free plan; the 7-day trial comes with €5 of AI model credits.
• Prices are in euros and exclude VAT. The per-seat price falls in volume tiers, and annual billing is 20% cheaper than monthly.
• Seats with hosted models are subject to fair-use limits; the Business Max seat at €99 gives five times the usage of a Standard seat.
• The mobile apps cover Chat and Agents only. Workflows and workspace settings need the web or desktop app.

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.

Langdock

Model-agnostic chat

One chat interface for leading models from several providers. Seats can include hosted models under fair-use limits, or the workspace can bring its own model keys.

Agents

Custom AI agents for recurring tasks that work with connected tools and documents. A Governance add-on lets admins review, approve, flag or disable any agent.

Workflows

AI automations with unlimited steps under fair use. Chat & Agents includes 2,500 workflow runs a month, and larger packages are sold per workspace.

Integrations

57 integrations with 754 native actions, including Google Drive, Notion, Slack, Salesforce, Jira and Confluence, plus custom integrations and MCP.

API

A single EU-hosted API for the leading models, billed per token and separately from seat pricing.

Admin controls and deployment

SSO, SCIM and SAML on the Business plan, custom branding, and a dedicated or on-premise deployment for organizations with 1,000 or more seats.

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.
