Open source design infrastructure

Component libraries, developer tools, and color systems — built for the AI era. Free for everyone. Enterprise support when you need it.

Why we build this way

AI-first

Every component has llms.txt documentation. AI agents can discover, search, and use our tools natively. The API surface is designed for LLM comprehension.

Linux-native

Built on Linux, for Linux. Our themes run on Alacritty, i3, Sway, tmux, and Neovim. The same Base16 tokens that style our components style our desktops.

Zero dependencies

jera has no runtime dependencies. CSS is the library — Svelte wrappers are thin. gnosis-mcp needs only mcp + asyncpg. We don't ship what we don't own.

Open source

MIT licensed. Self-hosted on git.selify.ai, mirrored to Codeberg and GitHub. Enterprise support available for teams that need implementation help.
