How it works

Three steps from prompt to production code.

01
Connect the MCP URL
Drop one URL into Claude, Cursor, or any MCP-aware agent. Your API key gates access and meters usage.
02
Prompt for a component
Ask for a data table, a checkout, an entire dashboard. The agent calls get_registry_item and gets a resolved bundle.
03
Own the source
Real TypeScript lands in your repo — sub-components and npm deps included. No black-box dependency to upgrade or trust.
Why build69

A design system built for how you actually build now.

Own-the-code, always

No lock-in

Every component is pasted as plain source you can read, fork, and delete. There is no @build69/ui to install — just the files your agent wrote.

Five accent themes

Every surface re-tints from one OKLCH accent token.

282 components

Primitives to full page templates, across 18 categories — all on the same token language.

Metered by key

Free tier included. Usage is tracked per API key so you always know what your agents fetch.

Dark mode, for free

Every token has a tuned dark equivalent. Components adapt with zero extra work — try the toggle in the footer.

“Our agents ship UI that already matches the brand. Code review stopped being a design review.”
AMAna MoreauHead of Eng, Vela
“We deleted our component library and replaced it with a prompt. Onboarding a new app takes an afternoon.”
JTJordan TranFounder, Harbor
“The theming is the killer feature. One token flip and the whole product changes accent — light and dark.”
