Rubber Duck
Overview
Rubber Duck is an AI chatbot designed to assist developers with debugging by providing a virtual rubber duck to talk through code issues. Based on the classic rubber duck debugging method, it engages in conversational dialogue to help users articulate and solve programming problems. The tool is currently available as a web application, offering a simple, distraction-free interface for focused problem-solving.

What readers ask us about Rubber Duck
What is Rubber Duck?
A browser chatbot for thinking out loud about a bug: you describe the problem and the code, and it asks questions and offers possibilities rather than silently fixing anything.
Who is it for?
Developers stuck on something, where the value is articulating the problem clearly enough to see it — which is what the rubber duck method has always done.
What does it cost?
No figure is given in our directory entry, so none is claimed. Ask the maintainer what it costs, if anything.
What can it not do?
Run your code. It cannot see the stack trace you did not paste or the state you did not describe, so it reasons about what you tell it, which means the quality of the answer tracks the quality of your explanation.
Use cases
Explaining a bug out loud
Writing the problem down for someone else is what makes the answer obvious, and a chatbot is a patient listener.
Getting unstuck on a stack trace
Asking what a specific error usually means shortens the search through documentation.
Sanity-checking an approach
Describing a plan and being asked why is a cheap way to notice the assumption you skipped.
Alternatives
- A general chat assistant — Broader and equally unable to run your code.
- A colleague — Better judgement, and they are busy.
- A debugging tool in your editor — Sees the actual state, and only after you have a hypothesis.

What to pin down beforehand
Paste enough context
The answer is only as good as the code and the error you include. Leave out the environment and you get a generic reply.
Treat suggestions as hypotheses
It cannot test anything, so every proposed cause needs checking against the actual runtime.
