I made a new PostCSS plugin for the new CSS `corner-shape: squircle`. It creates smooth corners like in iOS (and nature). The plugin adjusts `border-radius` for squircle geometry and can add `corner-shape` automatically. github.com/postcss/postcs…
If you also want to support our work, we accept donations via opencollective.com/postcss or github.com/sponsors/ai/
Big news for PostCSS: CodeRabbit is sponsoring us with $500/month. This support lets us start preparing PostCSS 9. We’ll also use their AI agent to review PRs and catch issues before merge. Thank you, @coderabbitai, for supporting open source.
langflow. bun. ant-design. nuxt. vue. mermaid. pnpm. trpc. Over 600,000 GitHub stars between them, and CodeRabbit reviews it all, for free. Next stop: more than $10M into OSS over the next year, counted at what it costs us. Heres the how and why 👇 coderabbit.ai/blog/coderabbi…
We woke up to many new followers after the @rails and @AmandaBPerino announcement. Let us introduce ourselves. We're a design and engineering consultancy for devtools, AI, and cybersecurity startups, with a strong focus on Ruby and Rails. We authored and/or maintain 120+ open source tools, including @any_cable, Yabeda, Inertia Rails, TestProf, and @PostCSS. And we're hosting the second edition of our annual Ruby conference in San Francisco this November 10–12. The first two days are for technical talks and networking sessions, and the third day is for fun community events. More info: sfruby.com
Popular npm packages Keyv and Cacheable were hijacked, and malicious versions containing a malware were released to steal users’ access tokens. Protect your packages from the same fate with my guide, based on maintaining PostCSS and 100+ other projects: evilmartians.com/chronicles/the…
We updated our "Writing PostCSS plugin" guide to force protection against supply chain attack postcss.org/docs/writing-a…
We recommends following this guide for all PostCSS plugins to protect ecosystem from supply chain attacks
My new article is out! A systematic guide to releasing npm packages as safely as possible in 2026 (with a Skill to quickly apply the practices to your own open source projects). Not just “do X”, I cover real attacks and explain how each defense helps. evilmartians.com/chronicles/the…
The unsung heroes of our time. @43081j from the e18e.dev community cut 1 MB from caniuse-lite. With 700M installs per month, that saves around 700 TB of global internet traffic every month. github.com/browserslist/c…
Here is my post where I share how to create a perfect README.md for your open source project (sharing what I learned creating PostCSS, etc) evilmartians.com/chronicles/how…
I met @andreysitnik (creator of PostCSS, autoprefixer, size-limit) at my first ever conference. His talk was "how to make your open source project popular". Having a good README (beautiful and useful) is key.
You can also support PostCSS and our work around supply chain risks in open source by GitHub Sponsors github.com/sponsors/ai/

Celebrating my birthday today: 39. If you’d like to support my work (npm supply chain attack research and trying to fix social media with Slow Reader), I’d be truly grateful for a GitHub Sponsors donation. github.com/sponsors/ai/
Oh wow, @Amplify just sent me $50 through GitHub Sponsors. Huge thanks! Now I can get that screwdriver for the house that’s been sitting on my wishlist. github.com/sponsors/ai/
Supply chain attacks can’t be solved with one silver bullet. They need a systemic approach. For every dev layer (not just npm, but CI, Docker, and your editor) ask 4 questions: 1. How can we reduce dependencies? 2. Isolation 3. Update control 4. Review Thread ↓
