## What it is
wdb is a browser-based Python debugger built on a client-server architecture using WebSockets, with the server implemented in Tornado. It provides step-by-step debugging, breakpoints, in-program code execution, and code injection to pause running processes, fully supporting multithreaded and multiprocess programs.

## Use cases
- debug python programs in a browser instead of pdb
- step through python code with breakpoints from a web interface
- debug multithreaded or multiprocess python applications
- remotely debug a python process running on another machine
- pause a running python process via code injection
- trace exceptions in python code automatically

## When to choose
- you want a graphical, browser-based alternative to pdb
- you need to debug multithreaded or multiprocess python programs
- you want to debug a program on one machine from a browser on another
- you need to pause and inspect an already-running python process

## When to avoid
- you need a debugger for languages other than python
- you want an actively developed tool with recent updates and modern python support
- you prefer a terminal-based debugger like pdb or ipdb
- you need debugging inside an IDE with integrated tooling
