Auto-Unpublish NPM Packages Published Outside CI

A lot of vendors and open-source projects shared guidance on protecting users from downloading malicious NPM packages after the Shai-Hulud campaign — but almost nothing focused on protecting maintainers from accidentally (or maliciously) publishing them. So we built a small tool that continuously monitors your NPM packages and automatically unpublishes any version not produced by your CI workflow.

Auto-Unpublish NPM Packages Published Outside CI launched on November 27, 2025 with 6 votes, #2,995 of 9,796 launches that month and more than 75% of that year's launches.

  • Publish from GitHub Actions using multi-factor authentication2022 · github.com · ▲72

    The backstory about this GitHub Action: I discussed with an open-source maintainer why they publish npm packages from their local machine and do not use CI/CD pipelines. They said publishing should require human intervention and want to continue using multi-factor authentication to publish to the npm registry. This led to building the wait-for-secrets GitHub Action. It prints a URL in the build log and waits for secrets to be entered using a browser. Once entered, the workflow continues, and secrets can be used in future steps. The latest release of "eslint-plugin-react" to the npm…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
