Stacktower
XKCD-inspired dependency analysis for your GitHub repo
Stacktower turns any repo into the dependency tower from XKCD #2347 — then finds the blocks about to crumble. Vuln & health checks, tower diffs on PRs, README embeds, and an AI agent that audits your dependencies and tells you what to fix. OSS CLI included.
This all started with a blog post — "What happens when you take an XKCD joke too literally" — where I turned the famous dependency-tower comic into a real visualization experiment. The post landed far better than I expected (#1 on r/programming), which made me think: maybe this shouldn't just stay a fun side project.
So I turned Stacktower into a real developer tool. What it does today:
Paste any repo or package, get its tower — Python, JS, Rust, Go, Ruby, PHP, Java. No signup to try.
Vulnerabilities, license issues, and abandoned packages flagged right on the blocks holding you up.
An AI agent that reads how you actually use each dependency and recommends what to upgrade, replace, or remove.
A GitHub Action that posts tower diffs on PRs.
The CLI is fully open source (Apache-2.0).
