codezoom 2.0.1

Multi-level code structure explorer — interactive drill-down HTML visualizations

codezoom

Multi-level code structure explorer — interactive drill-down HTML visualizations.

codezoom generates a standalone HTML file that lets you explore a project's structure at multiple levels of detail:

1. External dependencies — direct and transitive packages from pyproject.toml + uv.lock
2. Package hierarchy — sub-packages and modules (via pydeps or file-tree fallback)
3. Module internals — functions and classes extracted from the AST
4. Class internals — methods and their call relationships

Click any node to drill down. Use breadcrumb navigation to go back up.

Examples

External dependencies (Python)	External dependencies (Java)
Project submodules	A submodule's children
Single-file view (Python)	Single-file view (Java)

Installation

Installing codezoom with uv

uv tool install codezoom

Installing codezoom with pip

pip install codezoom

Installing codezoom from source

git clone https://github.com/apposed/codezoom
uv tool install --with-editable codezoom codezoom

When installed in this fashion, changes to the codezoom source code will be immediately reflected when running codezoom from the command line.

Using codezoom as a dependency

uv add codezoom

or

pixi add --pypi codezoom

Usage

codezoom /path/to/project                     # auto-detect, output to codezoom.html
codezoom /path/to/project -o output.html      # custom output path
codezoom /path/to/project --name "My Project" # custom display name
codezoom /path/to/project --open              # open in browser after generating

Also works as a module:

python -m codezoom /path/to/project

Requirements

• Python 3.11+
• No mandatory runtime dependencies beyond the standard library
• Optional: pydeps for richer module-level import analysis (falls back to file-tree scanning without it)

Per-project configuration

Projects can include a .codezoom.toml or a [tool.codezoom] section in pyproject.toml:

[tool.codezoom]
exclude = ["tests", "docs", "__pycache__"]

The exclude list is passed to pydeps via -xx to omit modules from the hierarchy.
