What It Does

Bolt.new, built by StackBlitz, runs a full development environment entirely in your browser using WebContainers. You describe an app in natural language and Bolt generates, installs dependencies, and runs the code—all client-side, with no server round-trips. The result is remarkably fast iteration.

Setup in 5 Minutes

in a modern browser (Chrome or Edge work best). - Sign up for a free account. - No installation is needed—the entire Node.js runtime runs inside your browser tab.

Try This

Type: "Create a to-do app with drag-and-drop reordering, dark mode toggle, and local storage persistence." Bolt generates the project in seconds. Drag items around to test the interaction. Then type: "Add a priority field (high, medium, low) with colour-coded labels." Watch it refactor the existing code live in the editor pane.

Follow Along

Follow Along — Build a Flashcard App. - Test the app: create a "Biology" category, add 5 flashcards, and flip through them. - Add a scoring feature: "Add a `Got it' and `Missed it' button on each card. Track my score and show a percentage at the end of each category." - Review the generated code in the editor pane—find the state management logic and understand how it tracks scores. - Download the project and run it locally to confirm it works outside Bolt's environment.
