archinfo
Classes with architecture-specific information useful to other projects.
Decision gist · record as of 2026-08-14
Yes. archinfo is a lightweight, actively maintained library with zero dependencies, permissive licensing, and no known vulnerabilities. Install it if you are building or using cross-architecture tools that need programmatic access to architecture-specific metadata. It is not a general-purpose utility; install only if your project actually needs this information.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.12 or later.
- Low install friction with no runtime dependencies.
- Active maintenance: last commit 2026-08-14, released 2026-08-05.

What it is and what it does
archinfo is a library that encapsulates architecture-specific information into reusable classes. It was designed to support cross-architecture tools by providing a consistent, programmatic interface to CPU architecture details—instruction set properties, register layouts, calling conventions, and other platform-specific metadata. Rather than hardcoding architecture details throughout a tool, developers can query archinfo for the information they need.
The package has no runtime dependencies and is lightweight, making it suitable for embedding in larger analysis or reverse-engineering frameworks. It supports modern Python versions (3.12+) and has been actively maintained since its initial release in 2015.
Use it for
- Query CPU architecture properties in binary analysis or emulation tools that need to adapt behavior per target platform.
- Build cross-platform reverse-engineering frameworks that require programmatic access to architecture-specific metadata.
- Retrieve calling convention and ABI details for a given processor architecture in static analysis.
- Integrate architecture metadata into dynamic analysis or symbolic execution engines.
- Support architecture-agnostic tool development by centralizing platform-specific information.
