What is haydenbleasel?

This repository is a personal monorepo, essentially a single workspace where Hayden Bleasel keeps all of his personal projects organized together. Rather than scattering code across dozens of separate folders and setups, everything lives in one place. Hayden is a design engineer based in San Francisco who has built a number of well-known open source tools. He originally created projects like Streamdown, AI Elements, and Tersa while working at Vercel. Now he maintains a newer set of tools, including Ultracite, Files SDK, Batchwork, and Blume, and this monorepo serves as the home base for that ongoing work. The README itself is fairly minimal. It doesn't go into detail about how the monorepo is structured, what build tools it uses, or how to run the projects locally. Instead, it functions more like a hub: it lists the open source projects he's contributed to, links to his website and Twitter, and invites people to sponsor his work through GitHub Sponsors. For non-technical readers, the value here is mostly informational. If you're a founder, PM, or curious developer who has used one of his tools and wants to see what else he's working on, this repo is a starting point. It connects you to the individual projects he maintains, each of which has its own repository with its own documentation. The monorepo approach itself is a common pattern among developers who juggle multiple projects. It keeps related work in one spot, which can make it easier to share code between projects and maintain consistency. That said, the README doesn't explain the specific tradeoffs or tooling behind this setup, so anyone looking for technical detail would need to explore the code directly.
