The full story

matplotlib-cpp is a header-only C++ plotting library that wraps Python's matplotlib, with about 4,800 stars on GitHub. Its author wrote it at university; most users are academics, and over the years a backlog of hundreds of issues and pull requests built up that the author no longer had the energy to work through.

The author handed the project to Claude and reports that it fixed every open issue. The repository was updated on 9 November 2026 and its README now documents constraints such as string x-axis labels and headless saving.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
