objectgraph
A basic graph library
Decision gist · record as of 2026-08-14
Yes, if you need a lightweight, permissively licensed graph library for Python 3.10+. The single dependency, Production/Stable status, and zero known vulnerabilities make it low-risk. The aging maintenance status (no release in 266 days) is a minor concern for a stable library but worth monitoring if you plan long-term use. Suitable for small to medium graph use cases; verify performance characteristics for larger workloads.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction; single lightweight dependency on typing_extensions.
- Maintenance status is aging—last commit was 2026-01-02 and no release in 266 days—but the codebase is marked Production/Stable and supports current Python versions through 3.15.

Verify before relying

# Add nodes and edges via the graph API- Whether the graph implementation is optimized for large-scale use or primarily suited to small to medium graphs.
- Performance characteristics compared to other graph libraries or whether benchmarks exist.
- Whether the 'identifier' attribute requirement for nodes imposes practical constraints on object types.
What it is and what it does
Objectgraph is a graph library for Python 3 that lets you represent directed graphs where nodes are arbitrary objects (identified by a hashable 'identifier' attribute) and edges can carry arbitrary attributes. The library uses a non-standard edge model: multiple edges between the same pair of nodes are allowed, but edges with identical attributes are automatically collapsed into a single edge, reducing redundancy.
The package is a complete rewrite of the ObjectGraph class from altgraph, built from scratch for Python 3 with full test coverage. It depends only on typing_extensions and supports Python 3.10 through 3.15, including free-threading support in Python 3. The codebase is marked Production/Stable and has been actively maintained since its initial release in 2019, though recent activity has slowed.
Use it for
- Build dependency graphs or call graphs where you need to track relationships between arbitrary Python objects.
- Model network topologies or system architectures where nodes represent entities and edges represent connections with metadata.
- Analyze object relationships in memory profiling or debugging tools that need to represent object references.
- Implement graph-based algorithms on custom domain objects without writing graph infrastructure from scratch.
