importlab
A library to calculate python dependency graphs.
Decision gist · record as of 2026-08-14
Yes, if you need import graph analysis for a static analysis tool and can tolerate an unmaintained package. The library is stable and has no known vulnerabilities, but the abandoned status means no future updates or support. Suitable for projects that have already integrated it or need this specific functionality and can accept the maintenance risk.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6 or later.
- The package is archived and unmaintained, so compatibility with future Python versions is not guaranteed.
- Low friction to install.

What it is and what it does
Importlab is a library that analyzes Python source files to automatically infer their import dependencies and construct a dependency graph. It is designed primarily as a library for static analysis tools that need to process files in a specific order—ensuring each file's dependencies are analyzed before the file itself. The package includes cycle detection and ships with a command-line tool for inspecting import information.
The library depends only on networkx for graph operations and has low installation friction. However, the project is archived and abandoned, with no updates since 2024-05-03 and no active maintenance. While it remains functional for its original purpose, users should be aware that bugs will not be fixed and compatibility with future Python versions is uncertain.
Use it for
- Integrate with static analysis tools to ensure files are processed in correct dependency order
- Detect circular imports in a Python codebase to identify problematic dependency patterns
- Generate import dependency graphs for visualization or documentation of project structure
- Determine optimal file processing order for batch analysis tools that work on one file at a time

Before you install
Low friction to install. The package is abandoned (last commit 2024-05-03, repository archived) and has not been updated in over a year, so expect no maintenance or bug fixes going forward.
Requires Python 3.6 or later. The package is archived and unmaintained, so compatibility with future Python versions is not guaranteed.
