# Interfaces The Design Engineering Magazine by [Jakub Krehel](https://x.com/jakubkrehel). This is the markdown version of [https://interfaces.dev](https://interfaces.dev). Subscribe at https://interfaces.dev/#subscribe. ## What makes an interface feel great? I think a lot about what makes an interface feel great. When you go from using a good product to a great one, you can feel the difference. It's often hard to point to what makes the difference though. It's usually not a single thing, but instead a lot of small things that add up. In the age of artificial intelligence, speed alone is no longer an advantage. When most things can be replicated with a single prompt, just building something isn't enough. Products that stand out and last are built extremely well, with intent and extraordinary care. That's what Interfaces focuses on. Read by designers, engineers and design engineers at companies like Anthropic, Vercel, Stripe, Cursor, Figma, Microsoft, Google, Meta, Ramp, Shopify, Lovable, Cognition, Mercor, Profound, Polymarket. ## About Interfaces Design engineering is growing in popularity, but learning about it is still surprisingly difficult. The best information is scattered across blog posts, courses, tweets and all other corners of the internet. I write about a number of design engineering topics on my personal website and my posts have been read more than 1,000,000 times. Interfaces brings all of those topics together in one place, where I share everything I know and continue to learn about design engineering and building great interfaces. Interfaces is a completely custom-built digital magazine. Each issue is a deep dive into a specific topic and combines writing, interactive demos and code snippets. ## What you'll get A subscription gives you access to every Interfaces issue, plus the full resources and tools library, agent skills and the private Discord community. - **New issue every month.** At least one new issue is released every month. - **Interactive demos.** Explore concepts through interactive demos instead of text alone. - **Source code.** Most examples and demos include the full source code. - **Agent skills.** Skills based on topics covered throughout the magazine. - **Resources and tools.** A curated library of design engineering resources and tools I use. - **Private Discord community.** Discuss issues, share your work and meet other design engineers. ## Every issue so far Each issue covers a different design engineering topic from start to finish.

I write articles about a variety of design engineering topics on my [personal website](https://jakub.kr) and I built [oklch.fyi](https://oklch.fyi), a popular tool dedicated to OKLCH colors. I care deeply about craft and quality and I like to make people feel something through my work. I'm obsessed with details and I spend an unreasonable amount of time making sure they feel right. Previously, I worked at OpenSea and a few [other companies](https://www.linkedin.com/in/jakubkrehel/). You might have seen some of my work on [Twitter](https://x.com/jakubkrehel) or my code on [GitHub](https://github.com/jakubkrehel). - [Blog](https://www.jakub.kr/): My personal website. - [oklch.fyi](https://www.oklch.fyi/): A guide to OKLCH colors. ## Read three issues for free Get a feel for Interfaces. These three free issues give you a glimpse into what the magazine is about and what an issue looks like. - [Understanding gradients](https://interfaces.dev/magazine/issues/understanding-gradients) ([markdown](https://interfaces.dev/issues-md/understanding-gradients)) - [How I use shared layout animations](https://interfaces.dev/magazine/issues/how-i-use-shared-layout-animations) ([markdown](https://interfaces.dev/issues-md/how-i-use-shared-layout-animations)) - [Details that make interfaces feel better](https://interfaces.dev/magazine/issues/details-that-make-interfaces-feel-better) ([markdown](https://interfaces.dev/issues-md/details-that-make-interfaces-feel-better)) ## Start building great interfaces today Quality matters more than it ever has in software.
