AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

debugpy is a Debug Adapter Protocol implementation for Python that enables remote debugging of Python scripts and modules through standard debugger clients.

Low friction: pure Python wheel with no runtime dependencies. Active maintenance with recent releases (73 days since last update).

MIT license permits unrestricted use, modification, and distribution in both open and closed-source projects with minimal obligations.

Usage

pip install debugpy

import debugpy
debugpy.listen(("localhost", 5678))
debugpy.wait_for_client()
# Your code here

Requires Python 3.8 or later; a debugger client must be configured to connect to the listening host and port.

Verdict: debugpy is a stable, actively maintained debugger with zero known vulnerabilities, no dependencies, and permissive licensing. It supports Python 3.8–3.14 on Windows, macOS, and Linux.

Needs verification

Whether the debugger supports all Python 3.14 features or if there are known compatibility gaps.
Performance overhead or resource consumption when debugging large or long-running applications.
Whether subprocess debugging is enabled by default or requires explicit configuration.
