Utopia

Utopia was an online platform for designing, coding, and shipping React applications, pairing a visual design tool with a code editor over one source of truth. A 2020 Seedcamp portfolio company, it was built in the open as the MIT-licensed concrete-utopia/utopia monorepo (3.8k stars) with a first-party utopia-api npm library. The project has been dormant since mid-2025, utopia.app now serves a parked placeholder page, and no network API was ever published.

Utopia is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, Design, Low-Code, and React.
