dicebear-core 10.2.0rc1

Unique avatars from dozens of styles — deterministic, customizable, vector-based.

DiceBear Core (Python)

Deterministic, customizable, vector-based avatars — the Python port of the DiceBear core engine. It produces byte-identical SVG output to the reference JavaScript implementation (@dicebear/core) for the same style definition and options.

This package contains only the rendering engine. Avatar style definitions ship separately as language-agnostic JSON via dicebear-styles (or any other source of a DiceBear style definition).

Installation

pip install dicebear-core

Requires Python 3.10 or newer.

Usage

import json
from importlib.resources import files

from dicebear import Avatar

# Load a style definition (here from the dicebear-styles package).
style = json.loads(
    files("dicebear_styles").joinpath("adventurer.json").read_text("utf-8")
)

avatar = Avatar(style, {"seed": "John"})

avatar.to_string()    # the SVG markup
avatar.to_data_uri()  # data:image/svg+xml;charset=utf-8,...
avatar.to_json()      # {"svg": ..., "options": {...resolved options...}}

Avatar accepts either a raw style-definition dict or a Style instance, plus an optional options dict:

from dicebear import Avatar, Style

style = Style(style_data)
Avatar(style, {"seed": "John", "size": 128, "backgroundColor": ["b6e3f4"]})

Development

This package lives in the DiceBear monorepo under src/python/core. See CONTRIBUTING.md in the repository root for the full workflow.

cd src/python/core
pip install -e ".[dev]"
ruff check .
mypy src
pytest

The decisive check is tests/test_parity.py, which asserts byte-identical output against the shared fixtures in tests/fixtures/parity/ (generated from the JavaScript reference).
