What Open WebUI does well
- It is multi-user from day one, with roles, groups and per-resource permissions, single sign-on and automated user provisioning.
- It runs wherever Docker, Kubernetes or Python does: macOS, Linux and Windows.
- Retrieval is built in, with vector search or full-document context, hybrid BM25 search and reranking.
- It connects to Ollama and any OpenAI-compatible API, so one interface fronts local and hosted models.
- Anyone can use, modify and redistribute it, and its code up to v0.6.5 remains BSD-3-Clause.
Switching from Open WebUI
01
Install ToolPiper
Free, with no account. It runs on Apple Silicon Macs with macOS 26 or later.
02
Adopt the models behind it
An Open WebUI server holds no models. If Ollama was its backend, ToolPiper finds that library and asks once to adopt it. Each GGUF is hardlinked into its own store, so nothing is copied or downloaded again.
03
Export your chats first
Your conversations live in Open WebUI's data volume. Export the ones you want to keep from its interface before you remove the container.
Common questions
Is Open WebUI free?
Yes. Open WebUI is free to use as it comes, at home and at work. Its enterprise license, for white-labeling and rebranding, is sold by contact with no published price, as read on 2026-10-09.
Is Open WebUI free for commercial use?
Yes. Its license page says you can use, modify and redistribute it for any purpose. The one condition, from v0.6.6, is that the Open WebUI branding stays visible unless you have 50 or fewer users in a 30-day period, written permission as a contributor, or an enterprise license.
Is ToolPiper free?
Yes. The whole runner is free with no account and no caps: the llama.cpp engine, unlimited model downloads, the local OpenAI-compatible API, all speech and the MCP host. Paid plans start at $10/mo with Pro, which adds browser automation, files and Git, and RAG over your files.
Does Open WebUI need Docker?
Not strictly. Docker is the install its docs call officially supported and recommended for most users. It also installs with pip or on Kubernetes, and an early alpha desktop app runs it without Docker. ToolPiper is a native Mac app with no container to run.
Does Open WebUI run models itself?
The Open WebUI server does not: it connects to Ollama or any OpenAI-compatible API, so a working setup is the interface plus a model server. Its early alpha desktop app adds an optional built-in llama.cpp engine. ToolPiper runs llama.cpp inside the app.
Can I keep my models and chats?
If you ran Open WebUI as a server, your models were never inside it. They belong to the backend it pointed at, and when that is Ollama, ToolPiper adopts the library in place. Your conversations live in Open WebUI's data volume, so export the ones you want from its interface before you remove it.
