Julien Thibeaut

Design Engineer

Building software with a focus on design, detail, and function.

I'm building a design-engineering studio working with AI companies on interfaces, systems, and marketing sites.
Recent collaborations include: Cloudflare, LMArena, and Antimetal.

Some of my work:

prompt-kit – components for AI interfaces
zola – open-source chat app
motion-primitives – library of animated components
lab – archived prototypes and interface studies

I share notes and updates on X, and open-source code on Github.

I curate playlists every month and run every day.
