You insert `web_pdb.set_trace()` into your code, and when execution reaches that point, a web UI opens on a configurable port (default 5555) where you can step through code, inspect variables, and run PDB commands. The interface shows the current file with breakpoint markers, local and global variables, and command history.\n\nSince v2.0, Web-PDB has no external dependencies beyond Python's standard library (it uses asyncio for the HTTP server). It works with Python's built-in `breakpoint()` function via the `PYTHONBREAKPOINT` environment variable, and includes a `catch_post_mortem()` context manager for automatic post-mortem debugging on unhandled exceptions. The project is in minimum maintenance mode\u2014bug fixes and Python version compatibility are prioritized, but new features are not actively developed.","worth_installing":"Yes, if you need remote or browser-based debugging of Python scripts. The zero runtime dependencies, recent maintenance, and permissive license make it a low-risk addition. Not suitable if you require active feature development or need to debug in environments where a separate HTTP server thread is problematic (e.g., some serverless runtimes). Single-session browser limitation is a minor gotcha for team debugging."},"id":"web-pdb","links":{"html":"https://skillfed.io/packages/web-pdb","md":"https://skillfed.io/packages/web-pdb.md","pypi":"https://pypi.org/project/web-pdb/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-21","license_spdx":null,"license_treatment":"permissive","name":"web-pdb","python_support":"supports_current","summary":"Web interface for Python's built-in PDB debugger"},"popularity":{"monthly_downloads":82641,"position":14148,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.1"}
