Design engineering at Bolt: shipping components with AI agents

At Bolt, our core web platform, bolt.eu, serves up to 60M users a year across across 50+ markets and relies on a shared design system of more than 110 UI components. We updated our front-end pipeline so designers can ship working code directly into our production library using AI coding agents. By replacing informal handoffs with a unified review model, we reduced routine component delivery time from a week to an hour.
