Xkcd #2347 lived in my head, so I built the dependency tower for real
I finally got tired of XKCD #2347 living rent-free in my head, so I built Stacktower: a tool that takes any real package’s dependency graph and turns it into an actual tower of bricks. Along the way I had to wrestle some surprisingly spicy problems. Full blog post here: https://stacktower.io The result is half visualization tool, half love letter to the chaos of modern dependency trees. Open-source, works with PyPI, Cargo, npm, and more. Code: https://github.com/matzehuels/stacktower
In plain words
Stacktower visualizes software package dependency graphs as brick towers, inspired by the XKCD #2347 comic about dependency complexity. It works with multiple package managers including PyPI, Cargo, and npm, transforming abstract dependency trees into concrete visual representations. Designed for developers who want to understand and explore the intricate relationships between packages in their projects, the open-source tool combines visualization with accessibility across different programming ecosystems.

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it.

Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
