Asynchronous API for downloading images, tags, and metadata from image board sites (e.g., Danbooru, Safebooru, Yandere). Ignore the downloaded files.

Installation

pip install waifuboard

Requires: Python >= 3.9

Supported platforms and features

Platform Posts (download) Pools (download)
Danbooru
Safebooru
Yandere
Other platforms ... ...

Usage

Create a client (e.g., DanbooruClient) and call the download method of the corresponding component, such as client.posts.download(...) or client.pools.download(...). For parameters, please refer to the download method docstrings in the code.

import asyncio
from waifuboard import DanbooruClient


async def main():
    # Create a client, which will be used to interact with the API
	client = DanbooruClient(
        max_clients=8,  # The maximum number of clients to create, which is used to limit the upper limit of the global concurrent request count. If it is None or a non-positive number, the limit is not applied
        directory="./downloads",  # The root directory for storing files of the current client platform
        proxy_url="http://127.0.0.1:7890",  # The URL used to connect to the proxy server. The scheme must be one of "http", "https", "socks5", "socks5h", and the form is {scheme}://{[username]:[password]@}{host}:{port}/ or {scheme}://{host}:{port}/, for example "http://127.0.0.1:8080/"
        proxy_auth=None,  # Any proxy authentication information, in the format of a two-tuple of (username, password). Can be bytes type or str type containing only ASCII characters. Note: The auth parameter parsed from proxy_url is used first. If no auth is parsed from proxy_url and proxy_auth is not None, the proxy_auth parameter is used to add authentication credentials to proxy_url
        proxy_headers=None,  # Any HTTP header information for proxy requests. For example, {"Proxy-Authorization": "Basic <username>:<password>"}
        proxy_ssl_context=None,  # The SSL context used to verify the connection to the proxy server. If not specified, the default httpcore.default_ssl_context() is used
        max_connections=100,  # The maximum number of concurrent connections that can be established
        max_keepalive_connections=20,  # The number of long connections that can be maintained below this value. This value should be less than or equal to max_connections
        keepalive_expiry=30.0,  # The time limit for idle long connections (in seconds)
        max_attempt_number=5,  # The maximum number of attempts
        default_headers=True,  # Whether to set default browser headers
        logger_level=logging.INFO,  # The log level
    )

	# Download posts
	await client.posts.download(
		limit=200,
        all_page=True,
		tags="k-on!",
		save_raws=True,
		save_tags=True,
	)

	# Download pools
	await client.pools.download(
		limit=1000,
		query={
            'search[name_matches]': 'k-on!',
        },
        all_page=True,
		save_raws=True,
		save_tags=True,
	)


if __name__ == "__main__":
	asyncio.run(main())

If this project is helpful to you, a small star would be the unwavering motivation for me to keep the project open-source.

Download directory structure

Directory tree:

{directory}/
└─ {Platform}/
	└─ {Component}/
		└─ task/
			├─ images/
			│  └─ ...
			├─ tags/
			│  └─ ...
			└─ raws/
				└─ ...

where task is the unique identifier for the download task (e.g., post ID, pool ID).

Contributing

Contributions are welcome. To add new platforms or features:

  • Architecture

    • Platforms should inherit from waifuboard.booru.Booru (Base Client) and set the appropriate base_url and components.
    • Features/endpoints (e.g., Posts, Pools) should inherit from waifuboard.booru.BooruComponent (Base Component) and implement the download(...) interface consistent with existing platforms.
    • Reuse helpers from Booru (e.g., concurrent_fetch_page, concurrent_download_file, concurrent_save_raws, concurrent_save_tags).
  • GitHub workflow

    1. Fork this repository to your account.
    2. Create a new branch for your change: git checkout -b feat/<short-name>.
    3. Implement your platform/component and add minimal docs in this README.
    4. Run a quick local test to ensure basic functionality works.
    5. Commit and push your branch: git push origin feat/<short-name>.
    6. Open a Pull Request to main with a concise description (what/why/how to test).

Guidelines

  • Keep public APIs consistent with existing ones (method names, parameters, return types).
  • Add docstrings to new methods, especially download(...) parameters and behavior.
  • Follow the existing code style and logging patterns.
  • Avoid breaking changes; if unavoidable, call them out clearly in the PR.
