An online AI image search engine based on the Clip model and Qdrant vector database. Supports keyword search and similar image search.
- Use the Clip model to generate 768-dimensional vectors for each image as the basis for search. No need for manual annotation or classification, unlimited classification categories.
- OCR Text search is supported, use PaddleOCR to extract text from images and use BERT to generate text vectors for search.
- Use Qdrant vector database for efficient vector search.

| Hardware | Minimum | Recommended |
|---|---|---|
| CPU | X86_64 or ARM64 CPU, 2 cores or more | 4 cores or more |
| RAM | 4GB or more | 8GB or more |
| Storage | 10GB or more for libraries, models, and datas | 50GB or more, SSD is recommended |
| GPU | Not required | CUDA supported GPU for acceleration, 4GB of VRAM or more |
- For local deployment: Python 3.10 ~ Python 3.12, with uv package manager installed.
- For Docker deployment: Docker and Docker Compose (For CUDA users,
nvidia-container-runtimeis required) or equivalent container runtime.
In most cases, we recommend using the Qdrant database to store metadata. The Qdrant database provides efficient retrieval performance, flexible scalability, and better data security.
Please deploy the Qdrant database according to the Qdrant documentation. It is recommended to use Docker for deployment.
If you don't want to deploy Qdrant yourself, you can use the online service provided by Qdrant.
Local file storage directly stores image metadata (including feature vectors, etc.) in a local SQLite database. It is only recommended for small-scale deployments or development deployments.
Local file storage does not require an additional database deployment process, but has the following disadvantages:
- Local storage does not index and optimize vectors, so the time complexity of all searches is
O(n). Therefore, if the data scale is large, the performance of search and indexing will decrease. - Using local file storage will make NekoImageGallery stateful, so it will lose horizontal scalability.
- When you want to migrate to Qdrant database for storage, the indexed metadata may be difficult to migrate directly.
Note
This tutorial is for NekoImageGallery v1.4.0 and later, in which we switch to uv as package manager. If you are
using an earlier version, please refer to the README file in the corresponding version tag.
- Clone the project directory to your own PC or server, then checkout to a specific version tag (like
v1.4.0). - Install the required dependencies:
uv sync --no-dev --extra cpu # For CPU-only deployment uv sync --no-dev --extra cu124 # For CUDA v12.4 deployment uv sync --no-dev --extra cu118 # For CUDA v11.8 deployment
Note
- It's required to specify the
--extraoption to install the correct dependencies. If you don't specify the--extraoption, PyTorch and its related dependencies will not be installed. - If you want to use CUDA acceleration for inference, be sure to choose a CUDA-supported extra variant in this
step (We suggest using
cu124unless your platform doesn't support cuda12+). After installation, you can usetorch.cuda.is_available()to confirm whether CUDA is available. - If you are developing or testing, you can sync without
--no-devswitch to install dependencies required for developing, testing and linting.
- Modify the project configuration file inside
config/, you can editdefault.envdirectly, but it's recommended to create a new file namedlocal.envand override the configuration indefault.env. - Run this application:
You can use
uv run main.py
--hostto specify the IP address you want to bind to (default is 0.0.0.0) and--portto specify the port you want to bind to (default is 8000).
You can see all available commands and options by runninguv run main.py --help. - (Optional) Deploy the front-end application: NekoImageGallery.App is a simple web front-end application for this project. If you want to deploy it, please refer to its deployment documentation.
NekoImageGallery's docker image are built and released on Docker Hub, including serval variants:

Supports CPU inferencing | ) |
edgeneko/neko-image-gallery:<version>-cpu-arm |
(Alpha) Supports CPU inferencing on ARM64(aarch64) devices | ) |
Where <version> is the version number or version alias of NekoImageGallery, as follows:
| Version | Description |
|---|---|
latest |
The latest stable version of NekoImageGallery |
v*.*.* / v*.* |
The specific version number (correspond to Git tags) |
edge |
The latest development version of NekoImageGallery, may contain unstable features and breaking changes |
In each image, we have bundled the necessary dependencies, openai/clip-vit-large-patch14 model
weights, bert-base-chinese model weights and easy-paddle-ocr models to provide a complete and ready-to-use image.
The images uses /opt/NekoImageGallery/static as volume to store image files, mount it to your own volume or directory
if local storage is required.
For configuration, we suggest using environment variables to override the default configuration. Secrets (like API tokens) can be provided by docker secrets.
If you want to use CUDA acceleration, you need to install nvidia-container-runtime on your system. Please refer to
the official documentation for installation.

- Download the
docker-compose.ymlfile from repository.# For cuda deployment (default) wget https://raw.githubusercontent.com/hv0905/NekoImageGallery/master/docker-compose.yml # For CPU-only deployment wget https://raw.githubusercontent.com/hv0905/NekoImageGallery/master/docker-compose-cpu.yml && mv docker-compose-cpu.yml docker-compose.yml
- Modify the docker-compose.yml file as needed
- Run the following command to start the server:
# start in foreground docker compose up # start in background(detached mode) docker compose up -d
There are serval ways to upload images to NekoImageGallery
- Through the web interface: You can use the web interface to upload images to the server. The web interface is provided by NekoImageGallery.App. Make sure you have enabled the Admin API and set your Admin Token in the configuration file.
- Through local indexing: This is suitable for local deployment or when the images you want to upload are already on the
server.
Use the following command to index your local image directory:
The above command will recursively upload all images in the specified directory and its subdirectories to the server. You can also specify categories/starred for images you upload, see
python main.py local-index <path-to-your-image-directory>
python main.py local-index --helpfor more information. - Through the API: You can use the upload API provided by NekoImageGallery to upload images. By using this method, the
server can prevent saving the image files locally but only store their URLs and metadata.
Make sure you have enabled the Admin API and set your Admin Token in the configuration file.
This method is suitable for automated image uploading or sync NekoImageGallery with external systems. Checkout API documentation for more information.
The API documentation is provided by FastAPI's built-in Swagger UI. You can access the API documentation by visiting
the /docs or /redoc path of the server.
Those project works with NekoImageGallery :D
There are many ways to contribute to the project: logging bugs, submitting pull requests, reporting issues, and creating suggestions.
Even if you with push access on the repository, you should create a personal feature branches when you need them. This keeps the main repository clean and your workflow cruft out of sight.
We're also interested in your feedback on the future of this project. You can submit a suggestion or feature request through the issue tracker. To make this process more effective, we're asking that these include more information to help define them more clearly.
