GILD verdict
Pick Open WebUI when chats must stay in your infrastructure and Claude should sit beside local and other hosted models.
You host and upgrade it. Claude is the better choice when staff want Anthropic's own apps and connectors and a vendor-run service is worth seats plus usage at API rates. At 200 users Claude needs Enterprise, since Team stops at 150 seats.
GILD found no named team that has published choosing between them; Public Storage runs Claude as its main model inside Open WebUI, in Open WebUI's own undated customer story. Open WebUI is an interface you host for any model, and Claude is Anthropic's assistant sold by the seat. Open WebUI runs on your servers on your own keys at no license cost while the branding stays. Claude Team covers 2 to 150 seats with SSO, and Enterprise adds SCIM, audit logs, the Compliance API, and custom retention, with all usage billed at API rates.
Choosing between Open WebUI and Claude
Choose Open WebUI if
- Chats and documents must stay in your own infrastructure, including air-gapped networks.
- Staff should reach Claude through the API beside local and other hosted models in one interface.
- A team can host, patch, and upgrade the app and its database.
Choose Claude if
- Staff prefer Anthropic's own apps, projects, and connectors to a self-hosted interface.
- Nobody should run an assistant, and per-seat pricing with usage at API rates fits the budget.
- Security needs audit logs and the Compliance API from the vendor, on Enterprise.

What practitioners report, side by side
Each product's figures come from its own practitioners, for the group you pick.
Overall signal
Leaders and teams rate Claude +44, 118 points above Open WebUI at −74. Most of the gap is in complaints, with 28 of Open WebUI's 35 sources negative against 2 of Claude's 28.

Each of Open WebUI's authors wrote one source here, so each source is one vote.
A lead of a fifth of the votes reads positive and a lead of half strong positive, with the same lines below zero. The dots show each source, positive, mixed, negative. Run a pilot on your team's recurring tasks to measure how often answers are used without rework.
