* fix(middleware): replace BaseHTTPMiddleware HTTP middlewares with pure ASGI implementations
Starlette's BaseHTTPMiddleware (and the @app.middleware('http')
decorator that uses it) wraps the downstream app in an anyio task
group whose cancel scope tears down the inner task on every exit —
client disconnect, response complete, or any outer middleware bailing.
That CancelledError gets injected into whatever the inner task was
awaiting, so DB queries, embedding calls, and other long awaits get
killed mid-flight. Under aiosqlite the cleanup path then logs a
multi-page `terminate_force_close() not implemented` traceback at
ERROR for every cancelled DB call.
Open WebUI had four such middlewares stacked
(`commit_session_after_request`, `check_url`, `inspect_websocket`,
`RedirectMiddleware`) so a single cancellation would compound through
all four.
Move the four middlewares to a new `open_webui.utils.asgi_middleware`
module as plain ASGI classes (`__call__(scope, receive, send)`):
* `CommitSessionMiddleware` — was `commit_session_after_request`;
now also rolls back if commit fails
before releasing the connection.
* `AuthTokenMiddleware` — was `check_url`; sets request.state
token + enable_api_keys + stamps
X-Process-Time via a wrapped send.
* `WebsocketUpgradeGuardMiddleware`
— was `inspect_websocket`; rejects
/ws/socket.io HTTP requests that
claim transport=websocket without a
proper Upgrade/Connection header.
* `RedirectMiddleware` — was the BaseHTTPMiddleware subclass;
same /watch + share-target rewrites.
Pure ASGI does not introduce a cancel scope around the downstream app,
so client disconnects propagate via `receive()` (the way ASGI was
designed) instead of being injected as CancelledError. Middleware
ordering is preserved.
https://claude.ai/code/session_01JSr4NZSskEUQvoJnavVXh8
* fix(middleware): CommitSessionMiddleware — rollback on downstream error, never commit failed requests
The first cut put commit() in a finally block, which meant that even
when a downstream handler raised, the middleware would still commit
whatever partial sync writes that handler had made before the
failure. That regressed the previous BaseHTTPMiddleware semantics
where commit only ran on the success path.
Restructure the failure handling:
* Downstream raised → rollback any pending sync work, release the
connection, re-raise so the outer error middleware turns it into
an error response. We never commit a request that did not complete.
* Downstream returned → commit. On commit failure, log loudly,
rollback, and re-raise. ScopedSession.remove() always runs in
finally so the connection cannot leak.
Document the inherent pure-ASGI limitation explicitly: by the time
`await self.app(...)` returns the response messages have already
been emitted, so a commit failure can no longer change what the
client sees on the wire. Buffering the response to gate it on commit
success would break streaming responses (chat completions, SSE) which
are core to Open WebUI; the trade-off is intentional. Routes that
need commit-before-send must manage the sync session explicitly.
Also drop unused `typing` imports flagged by review.

How to Install 🚀
Installation via Python pip 🐍
Open WebUI can be installed using pip, the Python package installer. Before proceeding, ensure you're using Python 3.11 to avoid compatibility issues.
-
Install Open WebUI: Open your terminal and run the following command to install Open WebUI:
pip install open-webui -
Running Open WebUI: After installation, you can start Open WebUI by executing:
open-webui serve
This will start the Open WebUI server, which you can access at http://localhost:8080
Quick Start with Docker 🐳
Note
Please note that for certain Docker environments, additional configurations might be needed. If you encounter any connection issues, our detailed guide on Open WebUI Documentation is ready to assist you.
Warning
When using Docker to install Open WebUI, make sure to include the
-v open-webui:/app/backend/datain your Docker command. This step is crucial as it ensures your database is properly mounted and prevents any loss of data.
Tip
If you wish to utilize Open WebUI with Ollama included or CUDA acceleration, we recommend utilizing our official images tagged with either
:cudaor:ollama. To enable CUDA, you must install the Nvidia CUDA container toolkit on your Linux/WSL system.
Installation with Default Configuration
-
If Ollama is on your computer, use this command:
docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main -
If Ollama is on a Different Server, use this command:
To connect to Ollama on another server, change the
OLLAMA_BASE_URLto the server's URL:docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=https://example.com -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main -
To run Open WebUI with Nvidia GPU support, use this command:
docker run -d -p 3000:8080 --gpus all --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:cuda
Installation for OpenAI API Usage Only
-
If you're only using OpenAI API, use this command:
docker run -d -p 3000:8080 -e OPENAI_API_KEY=your_secret_key -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main
Installing Open WebUI with Bundled Ollama Support
This installation method uses a single container image that bundles Open WebUI with Ollama, allowing for a streamlined setup via a single command. Choose the appropriate command based on your hardware setup:
-
With GPU Support: Utilize GPU resources by running the following command:
docker run -d -p 3000:8080 --gpus=all -v ollama:/root/.ollama -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:ollama -
For CPU Only: If you're not using a GPU, use this command instead:
docker run -d -p 3000:8080 -v ollama:/root/.ollama -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:ollama
Both commands facilitate a built-in, hassle-free installation of both Open WebUI and Ollama, ensuring that you can get everything up and running swiftly.
After installation, you can access Open WebUI at http://localhost:3000. Enjoy! 😄
Other Installation Methods
We offer various installation alternatives, including non-Docker native installation methods, Docker Compose, Kustomize, and Helm. Visit our Open WebUI Documentation or join our Discord community for comprehensive guidance.
Troubleshooting
Encountering connection issues? Our Open WebUI Documentation has got you covered. For further assistance and to join our vibrant community, visit the Open WebUI Discord.
Open WebUI: Server Connection Error
If you're experiencing connection issues, it’s often due to the WebUI docker container not being able to reach the Ollama server at 127.0.0.1:11434 (host.docker.internal:11434) inside the container . Use the --network=host flag in your docker command to resolve this. Note that the port changes from 3000 to 8080, resulting in the link: http://localhost:8080.
Example Docker Command:
docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always ghcr.io/open-webui/open-webui:main
Keeping Your Docker Installation Up-to-Date
Check our Updating Guide available in our Open WebUI Documentation.
Using the Dev Branch 🌙
Warning
The
:devbranch contains the latest unstable features and changes. Use it at your own risk as it may have bugs or incomplete features.
If you want to try out the latest bleeding-edge features and are okay with occasional instability, you can use the :dev tag like this:
docker run -d -p 3000:8080 -v open-webui:/app/backend/data --name open-webui --add-host=host.docker.internal:host-gateway --restart always ghcr.io/open-webui/open-webui:dev
Offline Mode
If you are running Open WebUI in an offline environment, you can set the HF_HUB_OFFLINE environment variable to 1 to prevent attempts to download models from the internet.
export HF_HUB_OFFLINE=1
