I reverse engineered top websites to build an animated UI library
Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback
I reverse engineered top websites to build an animated UI library launched on April 24, 2025 with 156 votes, #260 of 7,818 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This is a library of reusable animated UI components built with React and Framer Motion, created by reverse-engineering design patterns from popular websites like Clerk. It is designed for developers and design engineers who want to understand and implement sophisticated animations and component structures. The library provides ready-made components based on real-world examples from high-quality websites.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
